为了减少汽车废气排放 ,石油炼油厂现在正面对新的汽油质量标准的挑战。炼油厂不仅要从流化床催化裂解器 (ＦＣＣ)中得到具有高选择性、高辛烷值良好的底部裂化的最优产出汽油 ,还要使生产的汽油能降低汽车的废气排放。其中最困难的部分之一是降低汽油中硫的含量。因为它能使汽
To reduce car emissions, oil refineries are now facing the challenge of new gasoline quality standards. Refiners not only need to get the best gasoline of high selectivity and high-octane bottom cracking from the FCC, but also make the produced gasoline reduce the emissions of vehicles. One of the most difficult parts is to reduce the sulfur content in gasoline. Because it can make steam
