Product yields removal ofsulfur and nitrogen from the coal and the biomass and optical textures of the char were studied. The results show that the probability of tar formation can be simulated by normal distribution functionE while thatof tar decomposition by Weibull distribution function. Biomass prevents coal particles from caking togetherduring pyrolysis and therefore particulate char can be obtained. The biomass produces more hydrogenthan the coal during pyrolysis - and consequently promotes the removal of sulfur and nitrogen from thecoal. The effectiveness of pyrolysis in the removal of sulfur and nitrogen increases with the increase oftemperature the decrease of the degree of coal metamorphosis and the size of coal particle. The reactionbetween biomass char and the mesophase from the pyrolysis of caking coal obstructs the formation and development of anisotropic texturesKEY WORDSC high sulfur coale Taking coalf biomass To- pyrolysis rotary furnacu0×÷032℃0 EENSEA1966 AeEuf612Ejaueol0cEETYHCN MHT
