Product yields￡ removal ofsulfur and nitrogen from the coal and the biomassf aund optical textures of the char were studied. The re-sults show that the probability of tar formation can be simulated by normal distribution functionE while thatof tar decomposition by W eibull distribution function. Biomass prevents coal particles from caking togetherduring pyrolysisf 7and 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 de-velopment of anisotropic textures .KEY WORDS29high sulfur coalf- caking coalf-biomassS co - pyrolysisE- rotary fumaceμUO》x+0OBEOUEENSAD2+966 A∈Eu$6%W
