催化裂化汽油轻馏分醚化提高汽油辛烷值

ETHERIFICATION OF FCC LIGHT GASOLINE FRACTION TO ENHANCE OCTANE NUMBER

在醚化催化剂的作用下,催化裂化汽油轻馏分与甲醇进行醚化反应,能使催化裂化汽油的研究法辛烷值增加0.5—2.6个单位,马达法辛烷值增加1.2—3.0个单位。

The light fraction of FCC gasoline was etherified with methanol over anetherification catalyst for the purpose of enhancing the octane number ofFCC gasoline.It showed that the research and motor octane number can beincreased by 0.5—2.6 and 1.2—3.0 respectively.
