摘要: Disclosed is a continuous process for preparing exo-THDCPD by isomerization of endo-THDCPD, which comprises passing endo-THDCPD and hydrogen gas successively through a first reaction zone filled with a hydrogenation protectant and a second reaction zone filled with an isomerization catalyst to perform a hydroisomerization reaction so as to obtain exo-THDCPD, wherein the hydrogenation protectant is a supported metal hydrogenation catalyst, and the isomerization catalyst is a metal-modified molecular sieve catalyst. The process can effectively convert endo-THDCPD to exo-THDCPD, with a conversion of greater than 86% and a target product selectivity of greater than 94%. This process is clean and green, and it can achieve a continuous operation of more than 2000 hours and has an industrial application prospect.

摘要: The present invention provides a process for preparing a catalytic cracking catalyst, which is characterized in that the process comprises: mixing raw materials including a rare earth-containing NaY molecular sieve obtained by contacting a NaY molecular sieve with a rare-earth salt solution or a mixed solution of rare-earth salt solution and ammonium salt solution, filtering, and water-washing, an inorganic oxide binder and a natural mineral, slurrying and shaping into shaped bodies; hydrothermally calcining shaped bodies in an atmosphere condition where a pressure is externally applied and an aqueous solution containing an acidic substance or an alkaline substance is extennally added; and then ammonium-exchanging to remove the alkali metal. The present invention optimizes and shortens the preparation process of the catalyst, which can reduce the preparation cost, and the prepared catalyst has excellent heavy oil conversion ability, higher gasoline and diesel yield, lower coke selectivity, and relatively reduces the used amount of the molecular sieve in the catalyst.

摘要: Disclosed is a catalytic cracking process and a catalyst system, the process comprising a step of contacting a cracking feedstock with a catalytic cracking catalyst in the presence of a radical initiator for reaction under catalytic cracking conditions; wherein the radical initiator comprises a dendritic polymer and/or a hyperbranched polymer, the dendritic polymer and the hyperbranched polymer each independently has a degree of branching of about 0.3-1, and the dendritic polymer and the hyperbranched polymer each independently has a weight average molecular weight of greater than about 1000. The catalytic cracking process is beneficial to enhancing and accelerating the free radical cracking of petroleum hydrocarbon and promoting the regulation of cracking activity and product distribution; by using the process disclosed herein, the conversion of catalytic cracking can be improved, the yields of ethylene and propylene can be increased, and the yield of coke can be reduced.
