摘　　要：介绍了抚顺石油化工研究院开发的OCT-M催化裂化汽油选择性加氢脱硫技术及其在中国石油化工股份有限公司广州分公司0.20 Mt/a重油催化裂化汽油加氢装置进行首次工业应用试验的情况。该技术将催化裂化汽油切割为轻、重馏分,采用专门的催化剂对重馏分进行选择性加氢脱硫,脱硫后再与轻馏分调合,脱硫率高,汽油烯烃含量降低不大、抗爆指数损失小。工业应用初期标定结果表明:硫质量分数为400-600μg/g、烯烃体积分数为29.6％、研究法辛烷值92.4、马达法辛烷值81.0的重油催化裂化汽油经过该技术处理后。产物汽油硫质量分数为73-89μg/g、烯烃体积分数约21.8％,研究法辛烷值约90.5,马达法辛烷值约80.3,混合汽油质量收率为99.4％,达到了攻关指标。OGT-M FCC gasoline selective hydrodesulfurization technology developed by FRIPP and its first commercial application and, test in 4 000 b/d RFCC gasoline HDS unit of Guangzhou Company are expounded. Heavy distillates have been selectively hydrodesulfurized with the special catalyst and then the refined oil is blended with light distillates. So the technology is characterized by high desulfurization rate, less olefin reduction and low octane number loss. Initial evaluation result of the commercial application shows that with the new technology sulfur content in FCC gasoline has been decreased from 400 - 600 fjtg/g to 73 - 89 fig/g, olefin content decreased from 29.6% to 21.8%, RON dropped from 92.4 to 90.6, MON dropped from 81.0 to 80.3 and the mixed gasoline yield is 99.4%.
