摘　　要：基于对渣油中沥青质存在形态和反应机理的深入研究,开发了渣油改质的高活性催化剂,提出了沥青质脱金属和高效轻质化的工艺技术。劣质渣油催化临氢热转化技术(RMX)利用高效传质的高压临氢鼓泡浆态床反应器和高活性催化剂,使劣质渣油在相对稳定的浆液体系中转化为轻质组分,其渣油轻质化率大于95%,沥青质轻质化率大于90%,金属脱除率大于99%。RMX技术作为劣质渣油改质平台技术,可与现有固定床加氢和催化裂化工艺组合;与现有的延迟焦化加工路线相比,RMX组合工艺的轻质油品或化工原料收率增加33.13百分点。RMX技术是适应炼油厂向化工转型发展、产品提质增效和结构调整的优选技术。The new process technology was proposed to remove the metal contaminants from asphaltene molecules and to convert them into light components based on the studies of morphology and reaction mechanism of asphaltene molecules,and the special catalyst with high activity was developed to upgrade asphaltene molecules.Residue upgrading to maximize asphaltene conversion technology(RMX)with high pressure bubble slurry reactor and high active catalyst was developed to convert inferior residue into light distillates yields over 95%,asphaltene molecules upgrading rate over 90%and metal removal rate over 99%.RMX was combined with fixed-bed hydroprocessing and fluid catalytic cracking to process vacuum residue to produce 33.13 percentage points more light transport fuel or chemical feedstocks than delayed coking process.RMX can be chosen to transform a refinery into a chemical complex and produce high profit products.
