重油催化裂化催化剂LDO-70的工业应用试验

INDUSTRIAL APPLICATION OF LDO-70 FCC CATALYST PROCESSING RESIDUE FEED

在中国石油辽河石化公司催化裂化装置上进行降低催化裂化汽油烯烃含量的重油裂化催化剂LDO-70的工业应用试验。结果表明,LDO-70催化剂具有较强的降烯烃能力,催化裂化汽油烯烃体积分数可以降低5百分点,辛烷值损失0.6个单位,较好地解决了降烯烃与保持辛烷值之间的矛盾;与装置原用催化剂相比较,在主要操作条件大致相同的情况下,汽油收率增加1.63百分点,油浆产率降低0.99百分点,焦炭产率减少0.50百分点,轻质油收率提高1.02百分点,产品分布得到有效改善。

LDO-70 catalyst was a catalyst developed for reducing olefin content of FCC gasoline. The commercial trial of LDO-70 catalyst was carried out successfully in the FCC unit of PetroChina Liaohe Petrochemical Company. Results showed that LDO 70 catalyst could significantly reduce the olefin content of FCC gasoline, when olefin content reduced 5 percentage points, the RON loss was only 0. 6 units. As compared with the base case under similar operation conditions, it can be seen that the yields of gasoline and light oil increased 1.63 and 1.02 percentage points,respectively;the yields of slurry oil and coke reduced 0.99 and 0.50 percentage points,respectively; the product distributions were improved significantly.
