| 摘 要： | 在非等温加热条件下采用热分析技术（热重法TG和微商热重法DTG）进行了C-CO2气化实验。利用Popescu法对C-CO2气化反应的机理函数进行了推断。结果表明,反应级数模型（n=1）是C-CO2气化的最概然机理函数。由Popescu法求得的C-CO2气化过程的活化能和指前因子分别为165.86kJ/mol和8.80×... |

| Abstract: | Experiments of carbon gasification with CO2 were carried out by thermal analysis techniques(thermogravimetry TG and derivative thermogravimetry DTG) under non-isothermal heating conditions.Popescu method was applied to analyze the reaction mechanism of carbon gasification with CO2.Results indicated that the reaction order model(n=1) was the most probable mechanism function.Using Popescu method,the activation energy and the pre-exponential factor for the process of carbon gasification with CO2 are 165.86 kJ/... |
| Keywords: | Popescu method carbon-CO2 gasification reaction mechanism |
