摘　　要：沈北/大庆减压渣油中含有丰富的微晶蜡。将渣油亚临界丙烷脱沥青得到轻脱油,再经酮苯脱油-白土精制生产高熔点微晶蜡。说明大庆、沈北混合原油减压渣油经脱沥青等系列工艺处理生产光亮油和微晶蜡的技术可行性,提出了大庆、沈北混合原油减压渣油综合利用的途径。There is abundant microcrystalline wax in Shenbei/Taqing vacuum residue oil. Light deasphalting oil is often obtained from vacuum residue oil by subcritical propane deaspbalting process, then microcrystalline wax with high melting point can be produced by butanone-toluene solvent deoiling and clay-treated refining. In this paper, the technical and economic feasibility of producing bright stock and microcrystalline wax from the vacuum residue of Daqing and Shenbei mixed crude by deasphalting etc. processes was discussed according to the pilot plant test results .Utilization ways of vacuum residue of Daqing and Shenbei mixed crude were put forward.
