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-ⅡS strong acid resin type etherification catalyst on the 500,000 t / a light gasoline etherification unit of PetroChina Lanzhou Petrochemical Company was evaluated based on the hydrodesulfurized catalytic light gasoline. The results showed that during the calibration period, the mass fraction of C5 and C6 tertiary-olefins in the raw materials were all lower than the designed values. The calibration values of the two conversion rates were 71.06% and 55.06% respectively, which reduced the olefin content of gasoline. Etherified gasoline octane calibration value of more than 98.9, an average increase of more than 4.6 units of raw materials.
