摘要：
中国石油兰州化工研究中心等单位合作开发了催化裂化轻汽油醚化LNE 系列工艺技术，可满足生产乙醇汽油和非乙醇汽油炼油厂的不同技术需求。工业应用结果表明：LNE-1和LNE-2工艺的叔戊烯转化率分别为72.10%和91.41%，LNE-3工艺的叔戊烯预期转化率可达93%以上；在生产非乙醇汽油调合组分时，轻汽油经醚化后，RON提高2.2个单位；在生产乙醇汽油调合组分时，醚化产品油的RON可达100以上，是优质的高辛烷值汽油调合组分。

Abstract:
A series of technologies (LNE-1, LNE-2 and LNE-3) for FCC light naphtha etherification, jointly developed by Lanzhou Petrochemical Research Center of PetroChina and other institutes, were applied in refineries that produce ethanol gasoline or non-ethanol gasoline. The results show that the tertiary amylene conversions of the LNE-1 and LNE-2 technology are 72.10% and 91.41%, respectively and the expected tertiary amylene conversion of LNE-3 process is more than 93%. The research octane number (RON) of FCC light gasoline is improved by 2.2 units after etherification by LNE-2 technology and the product can be used as a non-ethanol gasoline blending component; while for ethanol gasoline blending component production, the RON of etherified product by LNE-3 technology reaches above 100.
Key words: FCC, light naphtha, etherification, industrial application
