Abstract：The briquetting mechanism of bio-briquette was investigated by a FTIR and SEM. The briquetting conditions of lignite/biomass was optimized by means of quadratic general rotary unitized design. A regression equation between ratio of rice husk and lignite and treatment time, treatment temperature and drop strength was proposed. The optimal processing parameters of bio-briquette are achieved as following: ratio of 27%～31%, treatment time of 20～21 min, treatment temperature of 146～153 ℃. Under high temperature, part of lignin is liquated to binding material, which has a bonding function to lignite. The fall strength of bio-briquette is increased without adding binders. The process can also dewater the internal water of Xian-feng lignite. High efficient utilization of lignite can be realized.
