Abstract: The feasibility of using semi-coke briquette as civil fuel was analysis from three aspects，semi-coke composition，molding technology and economy. In terms of composition，by comparing the indicators of current national standards for civil briquette with that of commercially available semi-coke products，it is found out that although the quality of semi-coke can be affected by various factors such as pyrolysis process，coal quality，particle size，etc.，the calorific value，total sulfur and volatile content indexes can always meet the corresponding requirements for the briquette coal. In terms of molding technology，the compound binder is mostly used in producing civil semi-coke making in conjunction with the cold-press molding technology of roller briquetting machine. The molded product is of good performance in combustion and pollutant emissions reduction. In terms of economy，the briquette is of considerable economic benefits under the current coal price system，no matter whether it is made from purchased semi-coke powder or made by a ranked coal clean conversion project which takes semi-coke civil briquette as its main product.
