CC-20D催化剂的工业应用

Commercial Application of CC-20D Catalyst

长岭炼油厂生产的CC-20D型催化剂具有活性高、焦炭选择性好、重油裂化能力、抗重金属污染能力强等特点,用于玉门炼油厂500 kt/a FCC装置后,大幅度提高了柴汽比,由原来的0.68提高到0.73,柴油收率最高可达38％,汽油的RON值由使用前的87提高到89～90,装置操作平稳,流化正常。

CC - 20D catalyst with high activity, good coke selectivity, high cracking capacity of heavy oil and high heavy metal resistance etc. was used on 500 kt/a FCCU of Yumen General Petrochemical Works. It could significantly increase the ratio of diesel to gasoline from 0.68 to 0.73 with diesel yield up to 38 % , RON of gasoline from 87 to 89 - 90. The unit could run smoothly.
