Abstract: By comparing the characteristics of density, gelatine and asphaltene content of the raw material and ethylene cracking tar

in the current delayed coking unit, this paper analyzed the feasibility of processing ethylene cracking tar in the delayed coking unit,

pointed out the problems that may exist in the processing of ethylene cracking tarthrough theoretical analysis and non-isothermal

reaction thermogrgrication analysis, put forwardthe corresponding solutions, and forecastedthe prospect of ethylene tar processing in

delayed coking unit by economic analysis.
