Abstract: A large amount of semi-coke powder produced by the semi-coke industry in Shanbei has been used as a fuel for civil use. Based on the briquetting-coking process and the experiments of making formed-coke for gasification by using semi-coke powder from Shanbei mixed with coking coal, the effects of the proportion of fat coal or 1/3 coking coal to the formed-coke quality are researched. The effects of several binders to the formed-coke are also discussed in this paper. Semi-coke powder with fat coal or 1/3 coking coal can produce formed-coke with high quality for gasification.

Key words: semi-coke powder, gasification, formed-coke
