Based on an antifouling and liquid-improving mechanism, the additive JJZ-1 was developed. The experimental results indicated that the additive JJZ-1 had evident effect on antifouling and liquid improving. Adding 100 ~ 400 μg · g
−1
additive JJZ-1 into five vacuum residues, the formation of foul in coking furnace tube can effectively reduced by 0.21 ~ 0.22%. The liquid oil yield increased by 1.50 ~ 1.68% in the delayed coking process. The coke yield and gas yield decreased by 0.80 ~ 1.10% and 0.55 ~ 0.81%, respectively. The characteristics of JJZ-1 additive were analyzed, and the mechanism for antifouling and liquid-improving was discussed.
