摘要
在实验室采用板波纹规整填料型树脂催化剂对经固定床临氢醚化后的催化裂化轻汽油进行了深度醚化的催化精馏工艺研究。试验结果表明 ,催化裂化轻汽油经固定床临氢醚化和催化精馏深度醚化后 ,C5叔碳烯烃的总醚化率达 90 .6 % ,C6叔碳烯烃总醚化率达到 6 1.5 %。将深度醚化后的轻汽油与重汽油调合后与原催化裂化汽油比较 ,研究法及马达法辛烷值均提高了 2 .2个单位 ,饱和蒸气压由 75 .6kPa降低到 5 6 .7kPa ,总烯烃体积分数由 4 2 .4 %降到 2 9.6 % ,使催化裂化汽油的质量得到较好改善。
Using etherified light FCC naphtha (initial boiling point to 75℃ fraction) from a fixed-bed hydro-etherification reactor as feedstock, a catalytic distillation process for further deep etherification was studied in the laboratory over resin structured packing type catalyst. The result showed that the conversions of tertiary amylene and tertiary hexylene reached 90.6% and 61.5% respectively. Mixing the deep etherified oil into the heavy portion of FCC naphtha at a natural ratio and compared with the original full range FCC naphtha, the RON and MON of the mixture increased by 2.2 units , the vapor pressure decreased from 75.6kPa to 56.7kPa, and the content of olefin dropped from 42.4% to 29.6%. The FCC naphtha quality was improved.
