【摘要】 用热天平和实验室固定床反应器,研究了煤焦H₂O/CO₂常压气化的反应动力学,煤气组成及无机盐或矿物质对其的影响。实验结果表明:可以利用调节进料气中CO₂的浓度或添加Ca或Fe催化剂来控制生成气中CO/H₂比。更多还原

【Abstract】 The reaction kinetics and gas components as well as the effect of inorganic salts or coal mineral on them in the coal char gasification process with H2O/CO2 mixture have been investigated by means of the thermobalance and the small scale fixed bed reactor. Experimental results show that it is possible to control the CO/H2 ratio of produced gas by adjusting CO2 concentration in feed gas and adding Ca or Fe catalyst into coal.更多还原
