摘　　要：Co-thermal chemical conversion of coal and biomass is one of the important ways to realize efficient and clean utilization of coal.In this study,a typical Ningdong coal-Yangchangwan bituminous coal and cow manure were used to study the synergistic effect of intrinsic alkali,alkaline earth metals(AAEM)and organic matter on the co-gasification of coal and biomass by thermogravimetry analyzer(TG).The results showed that AAEM had obvious synergistic promotion effect on the gasification of a bituminous coal-cow manure mixture in the isothermal gasification(1000℃),whereas the organic matter will show the opposite effect on the process.To further investigate the effect of organic matter on the gasification process,the influence of organic matter on non-isothermal(25-1000℃)gasification reaction was investigated with heating rate of 10℃/min,the kinetic parameters of the gasification reaction were obtained by Coats-Redfern method.The increase of biomass mass fraction in the sample facilitates the migration of alkali metals from the material to the solid phase.The possible mechanism of the synergistic effect of intrinsic AAEM/organic matter on the co-gasification process was proposed.
