The effect of pyrolysis temperature on distribution of products and migration of main elements (C, H, O, N, S) during pyrolysis of Shenmu bituminous coal was investigated in a fixed-bed quartz reactor. The results showed that with the pyrolysis temperature increasing from 500℃ to 900℃, the char yield decreased and the gas yield increased continuously, while the tar yield increased to a maximum of 9.2%(?) at 600℃ and then declined. When the pyrolysis temperature increased, the transfer ratios of C, H, O and N in the char decreased, and the transfer ratio of S in the char decreased firstly and then increased with the minimum ratio of 67.0% at 700℃. With the increase of temperature, the transfer ratios of C, H and O in the gas increased, and the transfer ratios of N and S in the gas increased firstly and then decreased at 800 and 600℃ with the maximum values of 28.8% and 27.9%, respectively. The transfer ratios of C, H and O in the tar increased firstly to the maximum values of 9.3%, 14.0% and 7.2% at 600℃, respectively, and then decreased, while the transfer ratios of N and S slightly increased with the pyrolysis temperature increasing. The transfer ratios of H and O in the water increased firstly to the maximum values of 14.5% and 48.5% at 700℃, respectively, and then decreased slightly with pyrolysis temperature increasing.
