摘要：Delayed coking is an economic and practical technic for the conversion of residua to naphtha and diesel. In this work, a 10-lumped reaction scheme is applied to investigate the industrial delayed coking process. The feed is decomposed to four lumps, including saturate, aromatics, resin and asphaltenes, and the products are decomposed to six lumps according to the boiling points. Industrial data from a Chinese petroleum refinery are used to validate the model. It is shown that the proposed kinetic model is able to predict yields of delayed coking products at a wide range of feedstock properties. On the basis of this model, the feed distribution and reaction temperature of an industrial delayed coking process are optimized, which significantly increases the economic benefits.
