美国莫比尔公司对催化裂化的一项重大改进——紧接式旋风分离器已经工业化,它可以消除提升管后的非选择性热裂化反应,最明显的效果是可以减少40％以上的干气组分(如甲烷和乙烷),提高汽油和馏分油收率以及汽油辛烷值,降低重燃料油收率。 One of the major improvements Catalytic Cracking at Mobil Corporation in the United States - the immediate cyclone has been industrialized to eliminate the non-selective thermal cracking reaction after riser tube. The most obvious effect is to reduce dry gas by more than 40% Components such as methane and ethane increase gasoline and distillate yields as well as gasoline octane numbers and reduce heavy fuel oil yields.
