加氢裂化工艺是一种石油加工工艺,即在较高压力和较高温度的反应条件下,重质油在催化剂作用下发生加氢、裂化和异构化反应,转化为轻质油(汽油、煤油、柴油或催化裂化、裂解制烯烃的原料)的加工过程。它与催化裂化不同的是在催化裂化反应时同时伴随有烃类加氢反应。加氢裂化实质上是加氢和催化裂化过程的有机结合,能够使重质油通过催化 Hydrocracking is a petroleum processing process in which heavy oil undergoes hydrogenation, cracking and isomerization reactions under the action of a catalyst under the reaction conditions of higher pressure and higher temperature and is converted into light oil (gasoline , Kerosene, diesel or catalytic cracking, pyrolysis of olefin raw materials) process. It is different from the catalytic cracking in the catalytic cracking reaction accompanied by hydrocarbon hydrogenation reaction. Hydrocracking is essentially an organic combination of hydrogenation and catalytic cracking processes that enables heavy oil to pass through the catalyst
