摘　　要：针对目前我国消费柴汽比逐年下降的趋势,压减柴油、减油增化成为炼油企业调整的重要方向。在多产石脑油加氢裂化技术的基础上,通过对催化材料和工艺技术的创新,开发了劣质柴油加氢裂化多产高芳潜石脑油技术,通过制备具有丰富介孔结构和中强酸性的催化剂,在适宜的工况下可将柴油中的芳烃组分高效地转化为富含芳烃的汽油馏分。采用该技术处理中石油某炼油厂催化柴油和焦化柴油混合油,重石脑油收率最高达35%,芳潜为47%左右。China’s consumption ratio of diesel/gasoline ratio has dropped year by year, it becomes an important direction for refinery to reduce the yield of diesel oil, cut down the production of oil products and increase the production of chemical feedstocks.Based on the development of prolific naphtha hydrocracking technology and through the innovation of catalytic materials and process technology, the Petrochemical Research Institute of PetroChina Company Limited develops a technology for producing high aromatic latent naphtha through hydrocracking of inferior diesel oil.A kind of catalyst with rich mesopore structure and strong acidity can efficiently convert the aromatic components in diesel into gasoline fractions rich in aromatics under suitable working conditions.The yield of heavy naphtha is up to 35% and the aromatic potential is about 47% when this technology is applied to treat the mixed oil composing of catalytic diesel and coking diesel in a refinery of PetroChina.
