摘　　要：随着原油资源趋于重质化、劣质化,将渣油转化为清洁可运输燃料是当前石油炼制行业面临的挑战。渣油中含有大量杂质和沥青质,传统工艺加工困难,悬浮床加氢技术是目前渣油转化的重要手段,催化剂在工艺过程中占有重要地位。对悬浮床分散型钼基催化剂合成的温度、压力、晶化时间、表面活性剂等影响因素进行了详细综述,阐释了MoS_(2)催化剂活性位的形成和作用机理,及加氢裂化各反应过程的机理及规律。As crude oil resources tend to be heavy and inferior,converting residue into clean and transportable fuels is a challenge facing the current petroleum refining industry.Residual oil contain a lot of impurities and asphaltenes,which make the traditional processing difficult.Slurry bed hydrogenation technology is an important mean of residue conversion,and the catalyst plays an important role in the process.In this paper,the factors affecting the synthesis of dispersed molybdenum-based catalyst in suspended bed,such as temperature,pressure,crystallization time and surfactant,are discussed in detail.The formation and mechanism of active sites,and the mechanism and regularity of various hydrocracking processes are described.
