英文摘要： Based on the situation of coking industry in Shanxi province, following the principle of efficiently comprehensive utilization of coal, the coking coal with poor quality will be used as feedstock for coal blending and coking. The production of coke for gasification can rationally utilize the excess capacity of coke production, which is the important measure for the promoting innovation of coking industry. The researches on the optimization of the preparation process of coke for gasification according to the inherent correlations among coking conditions, coal structure evolution and gasification reactivity present the clear goals and great theoretical and practical significance. In light of the differences of metallurgical coke and gasification coke, the probably critical problems for the production of gasification coke using the existing coking equipment must be projected. Therefore, it is put forward to reveal the mechanisms of coal characteristics and coking conditions influencing on the yields and compositions of coking products; understand the inter-relations among the physical structure, chemical structure and mineral composition of gasification coke; know well the inherent correlation among the characteristics of coal, coking conditions, coke structure and reactivity; optimize the existing process of coke production for the purpose of the maximization benefit. According to the main factors influencing the gasification reactivity determined through experimental researches, the prediction model of coke gasification reactivity is optimized. It is sure that this project will supply a strongly theoretical base for developing the production of gasification coke bases on the existing coking equipment.
