Porous SAPO-34 molecular sieve membranes supported on α-Al 2 O 3 substrates have been successfully prepared by in-situ synthesis. It is found that several synthesis times are needed and the placement of the substrate in the autoclave is important to prepare a defect-free SAPO-34 membrane. The best ideal selectivity of H 2 /N 2 and CO 2 /N 2 of the membranes is 11.17 and 7.09 respectively. N-butane has a permeability of zero, indicating that the membranes are defect-free and the permeability mechanism through the membranes is molecular sieving.

Abstract The surface and bulk structure of a Ni67Zr33 amorphous alloy prepared by the rapid quenching method changes drastically after activation by air. The results of gas adsorption, XRD, XPS, SEM and TA show that the Ni67Zr33 amorphous alloy changed into a new type of supported catalyst with three clearly discernible parts arising from partial crystallization of the amorphous alloy, formation of zirconium oxide due to oxidation of Zr, and surface enrichment of Ni. The three parts are: a crystalline or partially crystalline core; a middle layer of porous support mainly composed of ZrO2 surrounding the core; and thirdly, a layer of surface segregated, active Ni. In the hydrogenation of styrene the catalyst exhibits high activity and exclusive selectivity of styrene to ethylbenzene when compared with a Ni/ZrO2 catalyst prepared by the conventional impregnation method. The physical and catalytic features of the catalyst can be regulated by the oxidation conditions.

Abstract The review begins by describing the catalytic research activities which have taken place in petroleum refining, petrochemicals, environmental protection and C 1 chemistry during the 1980s in the Peoples Republic of China. Four unique, commercialized, catalytic processes are described in detail, and eight catalytic processes and catalysts to which major improvements have been made are introduced. Finally, the prospects for catalytic research in the 1990s are forecast.

Abstract A modified batch gas sampling-carrier gas flow (BGS-CGF) microcalorimetric method is described and discussed. The values of the heats of differential adsorption of ammonia on ZSM-5 measured by this method agree well with those obtained from other calorimetric techniques. The differential and integral heats of adsorption of ammonia on SiO 2 -Al 2 O 3 , on zeolites and on some commercial catalysts were determined. The calorimetric measurements of ammonia adsorption were used to characterise the acidity of those samples. The acidity of the samples measured by the calorimetric method were correlated with their activities evaluated on a pulse reactor.

Biorefinery based on biomass resources is an important approach for the oil refining and petrochemical industry to achieve sustainable development. Two types of biorefinery suitable for China’s biomass resources are presented in this paper. With sorgo and cassava as raw material, an ethanol-biorefinery for the production of ethanol-gasoline and chemicals is explored, and with rape seed and cotton seed oil as raw material, a biodiesel-biorefinery for the production of biodiesel and chemicals is also explored. The associated problems and measures taken are discussed in the end.
