A coupled model of material flow and value flow was established to solve the selection problem of four typical coking modes under complex market environment. The input and output of the four modes and the corresponding value transfer process in different scenarios were analyzed, and the indicator of resource-added efficiency were compared. The results showed that the value-added efficiency of liquefied natural Gas (LNG)?tar?benzene processing mode was 3%~10% higher than that of other modes in historical scenarios. The descending order of added efficiency of the industrial chain extension were naphthalene and benzene separated from tar and crude benzene (32%), LNG from coke oven gas (21%), methanol from coke oven gas (1%). However, in the virtual scenario of upward economic status, the value-added efficiency of methanol from coke oven gas was 36%~50% higher than other measures.
