The coker gas oil from Daqing, Shengli, and Liaohe, which are three famous oil fields in China, are studied. The properties, chemical composition, and structural composition of coker gas oil from Daqing, Shengli, and Liaohe saturated hydrocarbon are analyzed. The results show that nitrogen and sulfur content in Daqing coker gas oil is the lowest, and saturated hydrocarbon content is the highest, and Daqing coker gas oil is the most easily processed raw material, and Liaohe coker gas oil mediates between two raw materials, but Shengli coker gas oil is the most difficult to process. By comparing with vacuum gas oil and nitrogen, sulfur content and carbon residue in the coker gas oils is higher and saturated hydrocarbon content is lower. Shengli coker gas oil is a somewhat inferior raw material. The factor of effecting on the processing and use of coker gas oil are analyzed, and the processing ways of coker gas oil are put forward.
