| 摘 要： | 在此对自制脱氯剂GH1与高温煤气中的氯化氢反应等温动力学与高温脱氯过程反应动力学进行了研究。等温动力学得出反应的反应级数为1,表观活化能为10.9kJmol。基于固定床反应器恒定模式行为,采用化学反应控制、产物层扩散控制及两种混合控制对脱氯过程的研究结果表明:自制脱氯剂GH1与高温煤气中的氯化氢气体的反应主要受化学反应控制,同时产物层的扩散控制是不容忽视的。

| Abstract: | The HCl-removal from high temperature coal gas is an important subject of new thermal power generation technologies in the 21st century.The experimental data obtained from HCl-removal were analyzed by a model based on fixed-bed reactor and shrinking core models.It was found that reaction between sorbent and HCl vapor is of first-order with respect to initial HCl concentration and the apparent activation energy is 10.9 kJ/mol.The adsorption process is governed mainly by chemical reaction,but the effect of the product layer diffusion cannot yet be neglected. |
