The experimental results show: delayed coking for coal tar can obtain higher fuel oil yield, lower wax oil yield and better products distribution.
实验结果表明：煤焦油延迟焦化可以得到较高的燃料油产率，较低的蜡油产率和较好的产品分布。

The change rule that coking yield and coke VCM increase as the coking period shortens in the commercial delayed coking unit has been calculated by the model.
应用该模型计算出工业焦化装置成焦周期缩短后，焦炭收率和焦炭挥发分增加的变化规律；

An additive to increase delayed coker yield has been prepared based on the mechanism of enhancing light oil yield and reducing the yields of coke and dry gas.
