煤化学链气化制氢系统热力学分析

he performance of chemical-looping gasification process was investigated by the HSC Chemistry. The influence of different parameters including tempertuer, H2O/C,CaO/C on syngas were studied. The efficiency of hydrogen production were calculated for Lingnancang bituminite, Xiwujiang anthracite and Shanxi lignite under the optimum gasification condition, which proved that high efficiency could be also got under atmospheric condition. Besides, it was found that syngas characteristics changed with different parameters in the similar way to these three coals, and the main difference was caused by their different total gross and compostition of volatile. Without regard to the coal reactivity, the higher coal step was, the higher the efficiency of hydrogen production was.
