【Abstract】 The research results and processes of microwave technology application in the various stages of catalyst preparation were summarized. Application in supporters preparation could strengthen pore structural and be favored to the formation of new textural characteristics. Microwave drying leaded to an decrease in catalysts crystallize mean size, and an increase in active components dispersion as well as the formation of active centers. The interaction between active components and supporters could be reinforced under microwave calcinations, and the specific surface area increased much more, so that exhibited higher catalytic activity and selectivity. The studies have shown that application of microwave technology in preparation of catalyst is a promising method of improving catalytic efficiency,saving energy and reducing costs.更多还原
