以水热法合成了铜磷铝分子筛（Cu-AIPO4-5），并用XRD，ICP，SEM，FT-IR，NH3-TPD，H2-TPR，ESR和N2吸附脱附等手段对样品进行了表征结果表明，所合成的Cu-AIPO4-5分子筛具有AFI拓扑结构，结晶度高，无结晶态杂质；Cu2+进入到分子筛的骨架结构中，并使其Lewis酸和Brosled酸中心数量增加，弱酸性中心大大增强，强酸性中心消失；样品中的Cu存在多种形式，以骨架Cu物种为主，还存在有骨架外Cuo和双核Cu物种，部分样品具有缺陷结构Cu-AIPO4-5分子筛中存在着骨架Cu和缺陷结构两种可能的活性中心，对苯液相氧化具有良好的催化性能，苯酚选择性可达96%，收率可达6.9%

Anthraquinone working solutions used in hydrogen peroxide manufacture were selected as the test system to investigate the flow pattern transition behavior of foaming system in the trickle bed reactor (TBR) with the method of measurement and analysis of the instantaneous pressure drop fluctuations. The boundaries and the corresponding flow map for the foaming system were established for TBR packed with different size particles. It was found that the size of particles shows significant effect on the flow regime distributions. A theoretical model proposed by Cheng and Yuan and an empirical correlation by Bartelmus and Janecki were used to predict boundaries of the flow pattern transition for anthraquinone working solutions. Comparison between estimation and experimental results showed that the predicted boundaries of Cheng and Yuan theoretical model are consistent with the observations in the present work.

以Cr（NO3）3为Cr源用水热法合成了Cr-AIPO4-5分子筛，并用CDE，FT-IR和CBH对分子筛进行了表征，结果表明，已进入到Cr-AIPO4-5分子筛骨架结构中；焙烧后分子筛样品的L酸中心和B酸中心数量均大幅度增加，Cr主要以Cr（V）形式存在,将分子筛样品用于催化H2O2氧化苯制苯酚反应，苯酚收率最高可达4.7%，选择性可达99.5%以上。非骨架Cr物种是导致H2O2无效分解和选择性下降的主要因素，而骨架Cr物种是反应的活性中心，提出了以骨架Cr过氧化物为中间物种的可能的反应机理，并用原位红外光谱初步验证了中间物种的存在。

Deactivated palladium catalysts in the hydrogenation of anthraquinone were regenerated with ethanol, nitric acid, hydrogen peroxide, boiling water and steam, respectively. The deactivated and regenerated catalysts were characterized by XPS, ICP, TG, FTIR, TPD, XRD, etc., and studied in the hydrogenation of anthraquinone. The results showed that the main cause of catalyst deactivation is the coverage of the active component by deposits. The treatments by hydrogen peroxide and boiling water can effectively regenerate the deactivated catalysts.Anthraquinone route, palladium catalyst, deactivation, regeneration

A new working solution consisting of 2-pentylanthraquinone (PAQ) and 6-pentyl 1, 2, 3, 4-tetrahydroantraquinone (4HPAQ) was hydrogenated and then oxidized by O2 to produce H2O2. The oxidation reaction was conducted in a well-stirred batch reactor at 30～50℃ and 0.10～0.20MPa. By measuring the concentrations of generated H2O2 by iodometry, the intrinsic kinetics for the gas-liquid oxidation of 6-pentyl-1, 2, 3, 4-tetra-hydroanthacene-9, 10-diol (4HPAQH2, the only hydrogenated product in the hydrogenated working solution) with molecular oxygen were studied. An exponential model was employed to describe the reaction rate and the kinetic parameters were obtained. The results show that the reaction rate is 0.7 and 1.4 order in the concentration of 4HPAQH2 and oxygen pressure, respectively, and the activation energy for oxidation is 41.3kJ/mol.
