摘要： A solid heat carrier catalyst for thermal desorption of organic matter-contaminated soil and a method for preparing the same. A hollow alumina ball prepared by 3D printing is taken as a solid heat carrier, copper-nickel-vanadium composite oxide is taken as a catalytic active component, and vinyltriethoxysilane is taken as a masking agent. The ball has a diameter of 30 mm to 60 mm and a thickness of 1 mm to 2 mm. An outer surface of the ball is masked with the vinyltriethoxysilane; then the ball is pierced to make an inner surface thereof connected with the outside through channels; the ball is then immersed in a catalytic active component precursor solution; and finally, drying and calcination are performed to obtain the solid heat carrier catalyst for thermal desorption of organic matter-contaminated soil. This product is widely applicable to the field of thermal desorption of organic contaminants of soil.

摘要： In order to specify a catalytic converter, especially SCR catalytic converter, with maximum catalytic activity, this catalytic converter has at least one catalytically active component and additionally at least one porous inorganic filler component having meso- or macroporosity. The organic porous filler component has a proportion of about 5 to 50% by weight. More particularly, a diatomaceous earth or a pillared clay material is used as the porous inorganic filler component.

摘要： A method of preparing butadiene that includes supplying butene, oxygen, nitrogen, and steam into a reactor filled with a metal oxide catalyst, and performing an oxidative dehydrogenation reaction at a temperature of 300 to 450° C. as a reaction step; after the reaction step, maintaining supplying the butene, oxygen, nitrogen, and steam within a range within which the flow rate change of the butene, oxygen, nitrogen, and steam is less than ±40%, or stopping supplying the butene, and cooling the reactor to a temperature range of 200° C. or lower and higher than 70° C. as a first cooling step; and after the first cooling step, stopping supplying the butene, oxygen, nitrogen, and steam or stopping at least supplying the butene, and cooling the reactor to a temperature of 70° C. or lower as a second cooling step.
