摘要: 在固定床反应器中研究了自制的脱氯剂与高温煤气中HC1气体的反应动力学,得出在550℃时反应受通过产物层的扩散和化学反应反控制,两埂的阻力之比为0.138。同时研究了温度和进口HC1气体浓度对该反应影响,得出反应对于气相HC1为一级反应。Abstract: The kinetics of the reaction between the sorbent self prepared and HCl in a gas stream simulating high temperature coal gas was investigated under certain conditions. The experimental results obtained were analyzed by a shinking core model of diffusion and chemical reaction control. The effects of reaction temperature and inlet HCl concentration on reactivity of sorbent were studied in a fixed bed reactor.
