With the increasing of the economy and population, the demand of the ethylene cracking raw material increased year by year, and the problem that the competing demands for ethylene cracking raw materialin our country became more obvious.As the ethylene cracking raw material, the hydrogenation tail oil was also becoming more and more valued.Advantages and problems in production of the hydrogenation tail oil as cracking raw material of the ethylene were summarized.The influence factors (such as raw material property, pyrolysis temperature, residence time, hydrocarbon pressure, metal catalysis) of coking process were introduced mainly.Besides, according to some domestic and overseas research achievements in this field in recent years, the corresponding inhibition measure which included raw materials and process conditions optimization technology, adding coking inhibitor technology, furnace tube surface pretreatment technology, new material furnace tube and enhancement of heat transfer in the furnace tube furnace tube technology during the process of cracking furnace coking were introduced especially. The measures will provide a reference for the invention of new inhibiting coking technology.
