The reckoning diagram of coke yield for domestic coal resource is obtained on basis of first-hand date of thermal test and analysis fo r20 coke ovens by almost ten years' work.
Increases in throughput, resid blending ratio and gasoline octane as well as drop in coke yield can be obtained after the catalyst mixing.
Additionally, adjusting the air flow to achieve a reasonable coke yield also increased the heat of cracking into a region also consistent with residual operation.
