• Reaction rate enhancement of three‐phase hydrogenation using the Taylor flow reactor

  Abstract A gas–liquid–solid three‐phase reaction was conducted in a Taylor flow reactor to improve the apparent reaction rate by enhancing the mass transfer rate of the gas component to the surface of the solid catalyst through the liquid. Hydrogenation of α‐methyl styrene (AMS) was the model reaction. The reactor was an aluminum tube with a length of 300 mm and an inner diameter of 4 mm. A thin alumina layer was formed on the inner wall and palladium was used as the catalyst. Hydrogen and AMS were introduced into a T‐joint installed at the upper stream of the reactor to form a gas–liquid Taylor flow. The AMS conversion obtained using the Taylor flow was higher than that obtained without the flow. To examine the effect of the hydrogen absorption promotion by the circulating flow in the AMS slug, the total flow rate of the reactants was varied whereas the length of the gas and liquid slugs was maintained. Although the absorption increased owing to the faster surface renewal, only a slight improvement was observed. Conversely, when the total flow rate was fixed and the ratio of the gas slug length to the liquid slug length was increased, the apparent reaction rate improved significantly. These results indicate that diffusion in the thin liquid film directly toward the solid catalyst on the reactor wall was dominant for enhancing the reaction rate.

  γ-ブチロラクトンから1,4-ブタンジオールへの液相水素化反応を、担持Pt触媒にZrO₂を添加した触媒を用いて行った。ZrO₂を添加したことで、水素活性能を有するPtの分散度が向上した。Pt/SiO₂に比べ、ZrO₂を添加した触媒では、収率が1 %から53.9 %に増加した。（触媒中のZrO₂含有量33 wt%）、一方、Pt分散度が同程度であるPt/Al₂O₃上では、収率が約6 %であった。この結果よりZrO₂を添加することはPtの分散度を向上させるのみではなく、カルボニル基を活性化させる効果もあるため、著しく活性が向上したと考察した。

  有機合成において重要な反応であるBV酸化ではこれまで酸化剤に主として有機過酸を用いていたが、副生成物として有機酸が生成する。そこで過酸の代わりに酸化剤として副生成物がH₂OであるH₂O₂、触媒としてH型βゼオライトの酸点でカルボニル基を活性化させることにより、環境に低負荷な反応を行うことができる。しかし、酸化剤に用いるH₂O₂水溶液に含まれるH₂Oが酸点と強く相互作用し触媒を被毒し、活性や選択性の低下が起こる。そこで本研究では、cyclohexanoneからε-caprolactoneへのBV酸化反応において、H₂O₂水溶液を半回分操作で導入し、選択率の向上を検討した。

  Kohno Sachiko, Maeda Tomohiro, Ichihashi Yuuichi, Nishiyama Satoru

  Al板上に無電解メッキでZnおよびCuを担持したwall型Cu-ZnO-Al2O3触媒を用いて水性ガスシフト反応を行い、Ceの添加効果を検討した。共沈法で粉末のCu-ZnO-Al2O3触媒を調製する際にCeを添加するとシフト反応の活性が増大し、高CO2濃度条件下での活性を抑制できる。無電解メッキ法によるwall型触媒においても、Ceの添加効果を検討した。得られた焼成前の触媒前期体にCeをディップコートすることで、活性が向上することがわかった。

• Selective reduction of crotonaldehyde over Zr/MCM-41 prepared by grafting method

  Nishiyama Hiroo, Izumi Akiko, Ichihashi Yuichi, Nishiyama Satoru, Tsuruya Shigeru

  MCM-41-supported zirconium catalysts were prepared by using surface reaction between zirconium alkoxide and hydroxyl groups on the surface of MCM-41. The concentration of surface hydroxyl groups was controlled by changing evacuaton temperature prior to the grafting. Selective reduction of crotonaldehyde was carried out over the Zr/MCM-41 catalysts. The yield of crotyl alcohol, which is a corresponding unsaturated alcohol from crotonaldehyde reduction, was strongly affected by the evacuation temperature. The concentration of surface hydroxyl groups on MCM-41 will influence the dispersion state of Zr of the Zr/MCM-41 catalysts prepared by the grafting method.

• Hydrogen Transfer Activity of Tin-Incorporated Meso Porous Silica

  Nishiyama Satoru, Takagi Keiji, Izumida Hideaki, Ichihashi Yuichi, Tsuruya Shigeru

  Preparation procedure of Sn-incorporated in meso pores of MCM-41 has been studied for reduction of acetophenone to 1-phenylethanol. Tin was incorporated into the meso pores of MCM-41 by a template ion exchange (TIE in the following) method. Almost 20 wt% of Sn was loaded in the meso pores and ca. 70 % of template was still remained together. Calcination treatment to remove the residual template ions brought about significant collapse of the periodical hexagonal structure of MCM-41 and decrease of surface area because of heat of combustion of the template in the pores accompanying with sintering of incorporated tin. We have investigated the procedure to remove the template from the MCM-41 by rinsing with HCl before or after the tin incorporation to avoid vigorous exothermic combustion during the calcination. Almost 70-80 % of template was liberated by the rinse with HCl. The hexagonal structure and surface area were maintained after Sn incorporation. The rinse with HCl aqueous solution before the tin incorporation brought about an enhancement of specific activity, formation rate of 1-phenylethanol from acetophenone per incorporated amount of Sn. The rinse of HCl before the incorporation increased the specific activity by a factor of 2-3.

• Liquid-Phase Oxidation of Benzene over Vanadium Incorporated Heteropolyacid

  Sumimoto Shingo, Yamaguchi Shota, Ichihashi Yuichi, Nishiyama Satoru, Tsuruya Shigeru

  Phenol production in the chemical industry is currently carried out through the Cumene process in which three process steps are included and acetone is produced as a byproduct. Direct oxidation of benzene into phenol is desirable because one-step production of phenol is more economical. However the oxygenation of benzene has been known to be one of the most difficult oxidations. We have previously reported the liquid-phase oxidation of benzene to phenol with molecular oxygen under 4 atm at 303 K using V catalyst (V supported Al₂O₃ , V/Al₂O₃ ) in the presence of ascorbic acid as a reducing reagent for V species, although the leaching of V ions on Al₂O₃ was a serious problem of this reaction system. In this study, we have attempted the utilization of V incorporated heteropolyacid (V-HPA) as a catalyst. The V-HPA led to the remarkable decrease in the leaching of V ions and produced the similar amounts of phenol in comparison with that of the V/Al₂O₃ catalyst. We have also investigated the effect of the changing composition of the V-HPA. i.e., using NH₄⁺, Cs⁺ and Rb⁺ as a counter cation, and Mo and W as a polyanion. The V-HPA which is composed of Cs and Mo had the highest activity among the catalysts studied. The yield of phenol increased with the increase in the reaction time up to 1 h using the V-HPA catalyst composed of Cs and Mo, but leveled off with further increase in the reaction time. It seems that the redox cycle of the V species (V⁴⁺, V⁵⁺) participates during the oxidation of benzene.

• Synthesis of Lactone from Cyclic Ketone over Sn Supported Catalyst

  Kuwajima Masamichi, Ichihashi Yuichi, Nishiyama Satoru, Tsuruya Shigeru

  Baeyer Villiger oxidation of cyclohexanone to ε-caprolactone was studied over Sn/MCM-41 catalysts. Effects of Sn loading on MCM-41 and solvent were studied. Dependence of reaction temperature and H₂O₂ concentration were also investigated. The products were ε-caprolactone (the target molecule), δ-hexanolactone and γ-caprolactone. The yield and selectivity of ε-caprolactone were increased with the loading of Sn up to 15 wt% on Sn/MCM-41. At a higher loading, the yield and selectivity were decreased. The higher yield and selectivity of ε-caprolactone were observed in acetonitrile solvent than in MTBE, ethylene glycol or 1,4-dioxane. High reaction temperature and high concentration of H₂O₂ brought about decrease of the yield and selectivity of ε-caprolactone. The highest yield of ε-caprolactone (10 %) was obtained on 15 wt% Sn/MCM-41 at 343 K in acetonitrile at 2 of cyclohexanone/ H₂O₂ ratio.

• Enhanced Hydrogenation Activity of ZnO Catalyst Thermally Treated under UHV Atmosphere

  Kida Kohji, Takano Eigo, Ichihashi Yuichi, Nishiyama Satoru, Tsuruya Shigeru

  We have observed that activities of H₂-D₂ exchange reaction and 1,3-butadiene hydrogenation were enhanced on ZnO catalyst by thermal treatment under ultrahigh vacuum (UHV : pressure ≤ 10^-7 Pa). Temperature programmed desorption (TPD) of adsorbed H₂ was carried out over ZnO thermally treated under UHV and low vacuum (LV≈ 1 Pa). Hydrogen was adsorbed on the catalysts at room temperature or 473 K. On the LV-treated ZnO at 873 K (873-LV), two desorption peaks were observed at 650 and 800 K. On the UHV-treated ZnO at 873 K (873-UHV), a new desorption peak was observed in the range between 360 and 480 K in addition to the peaks observed on 873-LV. TPD over the surface on which H₂ and D₂ were co-adsorbed was carried out in order to determine whether each desorption peak came from dissociatively or molecularly adsorbed hydrogen. In the range between 360 and 480 K, remarkable desorpion peak of HD was observed on 873-UHV, whereas almost no desorption peak of HD was obserbed on 873-LV. The desorption peak of H₂ at 550 K was accompanied with HD desorption on 873-UHV in the case that the adsorption was carried out at 473 K. Therefore the desorption peaks at 360 and 550 K were ascribed to desorption of H₂ adsorbed on 873-UHV dissociatively. The desorption peak of H₂ at 620 K was not accompanied with HD desorption on 873-UHV in the case that the adsorption was carried out at room temperature. Therefore the peak at 620 K was ascribed to desorption of H₂ adsorbed on 873-UHV molecularly. These results suggest that new active sites which readily dissociate molecular H₂ were generated by the UHV-treatment of ZnO.

  Transparent TiO₂ thin film photocatalysts have been prepared on silica glass plate by an ionized cluster beam (ICB) method. In order to improve the electronic properties of these photocatalysts, transition metal ions V⁺, Cr⁺, Mn⁺, Fe⁺) were implanted into the TiO₂ thin films at high energy acceleration using an advanced metal ion-implantation technique. The combination of these ion beam techniques can allow us to prepare the TiO₂ thin film photocatalysts which can work effectively under visible light (λ > 450 nm) and/or solar light irradiation. The investigation using XAFS and ab initio molecular calculation suggests that the substitution of octahedrally coordinated Ti ions in TiO₂ lattice with implanted metal ions is important to modify TiO₂ to be able to adsorb visible light and operate under visible light irradiation.

  The titanium silicalite-2 (TS-2) catalyst exhibits a photoluminescence spectrum at around 450–550 nm as well as the distinct and characteristic photocatalytic activity towards the direct decomposition of NO into N₂, O₂ and N₂O at 295 K under UV irradiation. XAFS and photoluminescence investigations indicated that the charge transfer excited state of the titanium oxide moieties having a tetrahetral coordination plays a significant role in the photoluminescence and photocatalytic reactivities of the TS-2 catalyst.

• The Photocatalytic Reduction of CO2 with H2O on Titanium Oxide Catalysts.

  Masakazu ANPO, Hiromi YAMASHITA, Shin-ichi KAWASAKI, Yuichi ICHIHASHI

  UV irradiation of active titanium oxide catalysts in the presence of CO₂ and H₂O at 275K led to the photocatalytic reduction of CO₂. The characteristic features of the photocatalytic reduction of CO₂ with H₂O on various types of active titanium oxide catalysts were investigated by in situ photoluminescence, UV-Vis, XAFS, ESR, FT-IR and XPS spectroscopic techniques.
  The reactions on TiO₂ powders and Ti/Si binary oxides prepared by the sol-gel method produced methane as the major product while, on the highly dispersed titanium oxide anchored on a porous glass and zeolites, the formations of CH₄, CH₃OH, C₂-compounds, and CO were observed as the major products. The yields of the photocatalytic reactions strongly depended on the type of catalysts, the value of CO₂/H₂O, and the reaction temperature. In situ spectroscopic studies of the system indicated that the photocatalytic reduction of CO₂ with H₂O is linked to a much higher reactivity of the charge transfer excited state, i.e., (Ti³⁺-O^-)^3* of the tetrahedral coordinated titanium oxides species formed on the surface. Based on the detection of reaction intermediate species such as Ti³⁺, H atoms, and C radicals, the reaction mechanism for the photocatalytic reduction of CO₂ with H₂O has been proposed on a molecular scale.

  We propose H₂-D₂ titration method for evaluation surfaces of metallic catalysts, and have been applied to a study on the surface reconstruction of Pd foil model catalysts modified by the UHV treatment for H₂-D₂ exchange reaction. The UHV treatment brought about the reconstructed surfaces of Pd foil catalysts, and the improvement of H₂-D₂ exchangeactivity and the decrease of activation energy. The H₂-D₂ titration over the UHV-treated Pd foil catalysts indicated that the number of strongly adsorbed hydrogen atom species was increased by the UHV treatment. These results strongly suggest that the UHV treatment generates the newly active sites on Pd foil catalysts. The SEM study also supported the surface reconstruction of the Pd foil catalysts by the UHV treatment. In this report, we introduce the high sensitivity of the H₂-D₂ titration for hydrogen activation sites over a low surface area metallic catalyst.

  光触媒反応用の反応器として光透過性のマイクロ流動層反応装置の設計を行った．光触媒反応器はスケールアップに際して反応器の容積を単純に増大させることができない．これは光が反応器内部まで透過することが困難なためである．代表者のグループの先行研究で外部からの照射によって2 mm程度しか光は透過できない．そこで薄型の光を透過できるマイクロ流動層を３Dプリンタによって作成した．流動層の設計はCADにより行い，反応器のディメンジョン，ガス吹き込みポートの数や配置などを変えて良好な流動状態が得られる反応器形状を検討した．マイクロ流動層の横幅を大きくするとガスの流れが両端部で不良となり，中央部のポテンシャルコアの寄与が極めて大きくなることがわかった．流動層の厚さについては，3 mmまでであれば，流動状態に大きな影響は与えないこともわかった．最小流動化速度は，用いたテスト用樹脂粒子のサイズ，密度から推算される理論値（1.06 cm/sec）に近いことも確認できた． 本マイクロ流動層に光応答型トレーサー粒子を用いて流動状態を実現した状態で，光の照射を行いトレーサー粒子の色の変化から粒子が受け取る光量を測定した．光照射面積および光源と流動層の距離を一定として実験を行った．粒子の受光速度の評価には粒子に含まれる色素が酸発生剤によるpHの変化によって変色するので，受光による酸発生の速度定数（k1）を解析から求め用いた．ガスの線速度を変えそれぞれの条件でk1の値を求めた．最小流動加速度付近では，流動状態があまり均一ではなく，マイクロ流動層内でのトレーサー粒子の運動が不均一であまり活発ではない．そのため流動層壁面での粒子の変色が早く見かけ上k1の値が大きく求められる．線速度を最小流動加速度の7倍程度にすることで流動状態が均一で安定となり，この値をもってマイクロ流動層の評価することができることがわかった．

  本研究では、ベータゼオライト（HBEA）触媒上でのH2O2によるシクロヘキサノンのBaeyer-Villiger酸化（BV酸化）をモデル反応とし、マイクロ流動層型反応器により能動的に触媒、酸化剤、原料の共存時間を制御し、目的反応の維持と副反応の抑制を同時に達成する反応場の構築を目指している。 2021年度は、昨年度構築したマイクロ流動層型反応器をもちいて定常状態でのシクロヘキサノンのBV酸化を行った。従来のバッチ反応器によるBV酸化反応の結果と比較することで、マイクロ流動層型反応器が本反応に及ぼす影響について評価した。内径8 mmのガラスカラムをマイクロ流動層として用いて接触時間120 sでBV酸化を行ったところ、シクロヘキサノンの転化率は25%、目的生成物であるε-カプロラクトンの収率は7%を示した。また従来のバッチ反応器を用いたBV酸化では、同程度の転化率、収率を得るために6 hを要した。これら2つの反応器を用いた場合、触媒量と反応時間が異なるため、ε-カプロラクトンの生成速度（単位時間、単位触媒量あたりのε-カプロラクトンの生成量）を比較した。マイクロ流動層型反応器におけるε-カプロラクトンの生成速度は、バッチ反応器に比べて2.8倍高くなることがわかった。この優位性は、触媒層を流動化することで混合が迅速化されたこと、線速の増加により境膜拡散抵抗が減少したことなどにより発現したと考えられる。

• Selective reduction of diolefins over the metal catalysts surface-modified by UHV treatment

  In this study, the influence of surface structure has been investigated on the activity and selectivity of hydrogenation of 1,3-butadiene. Metal and metal oxide catalysts were thermally treated under ultrahigh vacuum (UHV<10^<-7> Pa) condition (the UHV treatment). The hydrogenation activity of 1,3-butadiene was markedly enhanced over supported Pd catalysts by the UHV treatment. The selectivity of 1-butene from 1,3-butadiene was increased by the UHV treatment. Thermodynamically, 2-butenes are more stable than 1-butene. The higher selectivity of 1-butene from 1,3-butadiene over the UHV-treated Pd catalysts strongly suggests that 1,2-addition of 1,3-butadiene proceeded preferentially at the initial stage of the hydrogenation. For the formation of 2-butenes, 1,4-addition of 1,3-butadiene was requested. The adsorption intermediate for 1,4-addition requires a more flat surface of Pd, like (111) basal plane. On a roughened surface, much more 1,2-addition will be expected than 1,4-addition. The high selectivity of 1-butene on the UHV-treated Pd catalysts indicates that the surface of Pd was roughened by the UHV treatment. These results show that the UHV treatment can modified the surface structure of metals and influenced the selectivity of terminal olefins. The activity on ZnO catalysts was also significantly enhanced by the UHV treatment. It is clearly indicated that the UHV treatment was also effective for the surface modification of the metal oxide catalysts.

  テンプレートイオン交換法(TIE法)を用いたMCM-41担持Sn酸化物触媒の調整 水熱合成直後のテンプレートを保持したMCM-41を用いて,含有するテンプレートとSnイオンを交換することでMCM-41メソ細孔内部に分散性良くSn活性点を形成させることを試みた。溶媒にはエタノールおよび希薄塩酸溶液を用いた。両溶媒共に効果的にSnとテンプレートが交換を起こしメソ細孔内にSnが導入された。テンプレートが除去されたことは,調製後の触媒のDTA-TG分析より確かめられた100%イオン交換されるのではないので,残存するテンプレートは空気流中焼成除去した。 アセトフェノンの液相還元反応 ステンレス製オートクレーブ中で2-プロパノールを遷元剤としてアセトフェノンの還元反応を行った。TIE相法で調製した触媒で,担持率15 wt%をSn担持率が超えると活性が急激に低下した。これは,残存テンプレートを除去する際に高温発熱でシンタリングしたためと思われる。焼成処理による除去ではなくHCl水溶液での化学処理でアルカリのテンプレートを除去することを試みた。HCl処理によって,単位Sn量当たりの活性(比活性)は増加した。 ベンズアルデヒド-アンモニア滴定法によるSn分散性の評価と活性 ベンズアルデヒドがZrやSn酸化物表面の塩基点と選択的に反応吸着することを利用して表面露出原子数(いわゆる分散度に準ずる値)を測定した。分散度の高いものほど生成物である1-フェニルエチルアルコール(1-PEA)が生成した。様々な調製法,テンプレート除去法の違いなどのパラメータが異なっていてもアンモニア滴定時に生成するベンゾニトリル量で一義的に整理することができる。これらの結果は,調製法などの差による活性の違いはSnの分散度の変化であることを示唆する。
