摘要: The present disclosure discloses a supported polymetallic oxide tandem catalyst, preparation method and application thereof, a surface of the support is supported with an oxide of metal A and then with metal vanadate nano-particles; and the oxide of metal A serves as a direct dehydrogenation catalytic site, and the metal vanadate nano-particles serve as a selective hydrogen combustion site. In the application of the tandem catalyst, dehydrogenation site and selective hydrogen combustion site are coupled at the nano-scale, and this coupling mechanism shifts the reaction equilibrium to the alkenes through the selective combustion of byproduct hydrogen, which effectively surpasses the thermodynamic limit; and meanwhile, the combustion of hydrogen releases chemical energy, and provides heat energy through direct heating, enabling the self-heating operation of the reaction. The present disclosure has the outstanding advantages of high single-pass conversion rate of light alkanes and high selectivity towards target product alkenes.

摘要: A fluidized catalytic reactor decouples the catalyst regenerator temperature from the catalyst reactor residence time. Regenerated catalyst is cooled before it contacts reactant feed. The regenerated catalyst may be cooled by heat exchange with oxygen supply gas, spent catalyst or other materials. The process and apparatus are especially useful for fluidized endothermic catalytic reactions.

摘要: A catalyst containing LF-type B acid preparing ethylene using direct conversion of syngas is a composite catalyst and formed by compounding component A and component B in a mechanical mixing mode. The active ingredient of the component A is a metal oxide; the component B is a zeolite of MOR topology; and a weight ratio of the active ingredients in the component A to the component B is 0.1-20. The reaction process has an extremely high product yield and selectivity, with the selectivity for light olefin reaching 80-90%, wherein ethylene has high space time yield and can reach selectivity of 75-80%. Meanwhile, the selectivity for a methane side product is extremely low (
