There is abundant microcrystalline wax in Shenbei/Taqing vacuum residue oil. Light deasphalting oil is often obtained from vacuum residue oil by subcritical propane deasphalting 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.
