摘要：

The composition and properties of China coker gas oil are analyzed and studied. The factors of effecting on the reaction of coker gas oil and measures that should be adopted are discussed. Research results show that China coker gas oil contains 86.04-86.87% C and 11.96-13.72% H, with an H/C atom ratio of 1.7. China coker gas oil contains 51.1-68.3% of saturated hydrocarbon, 24.8-37.4% of aromatic hydrocarbon, 5.7-11.5% resin and no asphalt. The aromatic carbon rate is 14-20% and alkyl carbon rate is 58-71%. The total cycle number R-T is 2.1-2.5 and the aromatic cycle number R-A is 0.8-1.3, with R-A/R-N slightly more than 1. The nitrogen contents of China coker gas oil is a bit high, which is more than 0.35%, so denitrogen should be taken into account to enhance the blending ratio of coker gas oil in FCC feed.
