摘要
以加氢脱硫后的催化裂化轻汽油为原料,评价了D 005-ⅡS强酸树脂型醚化催化剂在中国石油兰州石化公司50万t/a轻汽油醚化装置上的工业应用情况。结果表明,在标定期间,原料中C5,C6叔碳烯烃质量分数均低于设计值;二者转化率的标定值分别为71.06%,55.06%,降低了汽油烯烃含量。醚化汽油辛烷值的标定值达到98.9以上,较原料平均提高了4.6个单位。
The industrial application of D 005 - Ⅱ S strong acid resin catalyst for etherification in a 0.5Mt/a light gasoline etherification unit of Refinery of Lanzhou Petrochemical Company, PetroChina, was conducted with hydrodesulfurized catalytic cracking light gasoline as raw material. The results showed that the mass fraction of C5 and C6 tert - olefins in raw material was less than design value, the calibra- ted conversion values of the two tert - olefins reached 71.06% and 55.06% respectively, and the olefin content in gasoline decreased during the unit evaluation. The calibration value of octane number for etherified gasoline was over 98.9, increased 4.6 units compared with raw material.
