三种降低汽油烯烃含量裂化催化剂工业应用试验对比

COMMERCIAL COMPARISON OF THREE NAPHTHA OLEFIN REDUCTION CATALYSTS

在大连西太平洋石油化工有限公司重油催化裂化装置上进行了两种进口催化剂A和B及一种国产催化剂Orbit-3600B的工业应用试验。标定结果表明,石油化工科学研究院研制的Orbit-3600B催化剂的重油转化能力强,液体收率高,辛烷值高。与进口催化剂相比,汽油收率提高2.65～3.14个百分点,辛烷值提高约1个单位,总液体收率提高3.52～4.53个百分点。三种催化剂的降低汽油烯烃含量的能力相当,催化剂A、B和Orbit-3600B的汽油烯烃含量分别由使用常规裂化催化剂时的50％～55％降为38.8％,42.3％,38.5％。

Three catalysts, two imported catalysts A and B, and one domestic catalyst Orbit-3600B developed by Research Institute of Petroleum Processing were compared in a FCCU processing heavy oil in Dalian West Pacific Petrochemical Company. The test run results showed that Orbit-3600B had the advantages of high bottoms conversion ability, high liquid yield and higher naphtha octane number. Compared with the catalysts A and B, the naphtha yield increased by 2. 65 to 3.14 percentages, and the total yield of LPG, naphtha and LCO increased by 3. 52 to 4. 53 percentages. The olefin contents in naphtha using A, B and Orbit-3600B catalysts were reduced from 50% to 55% when using conventional catalyst to 38. 8% , 42. 3% and 38. 5% respectively.
