Abstract | Intrinsic characteristics of Naomaohu coal pyrolysis in a two-stage fixed-bed reactor have been investigated in this study. The pyrolysates were detected by the simulated distillation, ultimate analysis and GC-MS to analyze the effect of different temperature chars on pyrolysis volatiles. The results showed that the slight secondary reactions occurred when the volatiles flowed through the 100-400 degrees C char layer, the yield of pyrolysis gas increased slightly, the tar yield had a little decrease, the atomic H/C ratio was higher than that of blank contrast experiment, and the quality of oil increased. Under the action of 500-900 degrees C char layer, the drastic secondary reactions of the volatiles occurred, the yield of pyrolysis gas increased obviously, and the yield and quality of oil decreased. The results of two-stage experiments with and without char effect were similar to the temperature change, indicating that temperature played a major role in affecting the distribution of pyrolysates. Whereas char was beneficial for the content and quality of light oil in the low-temperature range, the process of volatiles through the semi-coke layer enhanced H(2)and CH(4)yield during the total temperature range. Char also had an adsorption action, which gradually weakened with the temperature increased. |
