法国石油研究院 (ＩＦＰ)开发了催化裂化 (ＦＣＣ)汽油超深度脱硫的Ｐｒｉｍｅ -Ｇ+ 工艺。脱丁烷后的ＦＣＣ汽油先进入一台反应器 ,在缓和条件下使二烯烃选择性加氢 ,将硫醇转化成重质含硫物质。选择性加氢反应器出来的物流再分离成ＦＣＣ轻石脑油 (ＬＣＮ)和ＦＣＣ重石脑油 (
The French Petroleum Institute (IFP) has developed the Prime-G + process for the ultra-deep desulfurization of FCC gasoline. The butane-fed FCC gasoline first enters a reactor, selectively hydrogenating the diolefins under mild conditions, and converting the mercaptans to heavy sulfur-containing substances. The stream from the selective hydrogenation reactor is then separated into FCC naphtha (LCN) and FCC heavy naphtha (
