摘　　要：为了提高催化裂化工艺中液化气、汽油和柴油的收率，减少焦炭生成，研究制备了CLK型减焦剂。采用MF—FCC多功能催化裂化实验装置，对在DVR—II型催化剂条件下的催化裂化产品分布进行评价。结果表明，添加减焦剂后重油转化率有明显的提高，汽油、柴油、液化气产率提高0．8％～1．2％，焦炭下降0．3％～1．2％。In order to increase the yield of liquefied gas, gasoline and diesel, decrease the yield of coke, the scorch retarder of CLK type is prepared. The catalytic cracking product distribution on the MF-FCC multi-function catalytic cracking device is evaluated under the condition of DVR- II catalyst. The result indicates that the conversion rate of heavy oil is improved obviously by adding the scorch retarder of CLK, the yield of gasoline, diesel and liquefied gas increases by 0.8% - 1.2%, the yield of coke decreases by 0.3% - 1.2%.
