英文摘要	The effects of five metal catalysts (k, na, ca, mg, and fe) on co2 gasification reactivity of fir char were studied using thermal gravimetric analysis. the degree of carbonization, crystal structure and morphology of char samples was characterized by x-ray diffractometry (xrd) and scanning electron microscopy (sem). the co2 gasification reactivity of fir char was improved through the addition of metal catalysts, in the order k>na>ca>fe>mg. xrd analysis indicated that na and ca improved the formation of crystal structure and that, mg enhanced the degree of carbon structure ordering. sem analysis showed that spotted activation centers were distributed on the surface of char samples impregnated with catalysts. moreover, a loose flake structure was observed on the surface of both k-char and na-char. finally, the kinetic parameters of co2 gasification of char samples were calculated mathematically.
