The sustainable development of iron and steel enterprises is restricted by the coking resources, and the reasonable use of coking resources is a problem to be solved at present. This paper analyzes these problems that exist in the present research of coke reactivity, the effect of harmful elements on metallurgical properties of coke, testing methods and other aspects. The research status of high reactivity coke and waste plastics and coal co-coking are summarized, and the research emphasis are put forward： the reaction mechanism and the change of particle sizes of coke in blast furnace should be re-oriented. Put forward reasonable requests to the quality of coke. According to the different quality of coke, it should make reasonable distributing system.
