重油高效转化关键技术的开发及应用

为了提高石油资源的利用率，促进重油高效转化以获取更多汽油和柴油等轻质油品，石油化工科学研究院（石科院）研究开发了重（渣）油加氢处理（RHT）技术及其与催化裂化（FCC）双向组合新工艺(RICP)等关键技术，显著提高了轻质油品收率。在RHT技术环节，石科院在保持原有重油加氢技术特点的基础上，开发了高效的新一代RHT系列催化剂和技术，其核心是大分子（沥青质、胶质等）加氢转化能力增强、小分子（多环芳烃）的进一步加氢饱和程度提升，增加加氢后重油的氢含量，同时伴随着金属杂质Ni和V、S和N的进一步脱除，对于提高杂质脱除率和延长装置运转周期，实现反应器和催化剂的高效利用，为催化裂化装置提供优质稳定的进料，生产更多、更优质的轻质产品发挥了重要作用。

DEVELOPMENT AND COMMERCIAL APPLICATION OF KEY TECHNOLOGY FOR EFFICIENT CONVERSION OF HEAVY OIL

To make full use of oil resources and obtain more light oil products,RIPP(Research Institute of Petroleum Processing) has developped RHT(Residue Hydrotreating Technology) and RICP(Residue hydrotreating Integrated with Catalytic cracking Process) key technology,an organic integration of RHT and RFCC,which can promote the heavy oil conversion and raise the light oil yield significantly.With regrad to RHT,on a basis of inheriting the advantages of RIPP’s existing technologies,a new generation of RHT series catalysts and technology has been developped,featuring with hydroconversion of more large molecular species(such as asphaltene and resin) and hydrosaturation of more cracked polyaromatics molecules along with enhanced capability of removing metals(Ni and V) and hetero atoms(S and N).Results from commercial application show that achievements including high removal rate of impurities,prolonged operation cycle,a highly efficient utilization of both the catalysts and the reactors,as well as providing high quanlity feedstock for FCC process are realized successfully.
