Chemical Engineering,2013,120(8):10典型的流化催化裂化装置(FCC)每年可产生大约200t的干气,这种混合排放气通常作为炼油厂燃料而被烧掉。然而,该排放气中含有大约40t的乙烯,如制成汽油或柴油可具有更大的价值。美国霍尼韦尔国际公司(Honeywell)旗下的环球油品公司(UOP LLC)正在开发一项用乙烯生产汽车燃料的新工艺,单程转化率大于40%。
Chemical Engineering, 2013, 120 (8): 10 A typical FCCU produces approximately 200 tons of dry gas annually, which is commonly burned as refinery fuel. However, the vent gas contains about 40t of ethylene, which can be of greater value as gasoline or diesel. UOP LLC, a unit of the Honeywell unit in the United States, is developing a new process for producing motor fuels from ethylene with greater than 40% conversion per pass.
