介绍了在预热催化反应反应器中对煤矿通风空气甲烷进行催化氧化的实验研究结果。该实验系统位于山东工业大学能源研究所，已用于研究启动流量系数(0.3-0.5)和启动功率(10千瓦-20千瓦)等启动条件对预热催化反应反应器启动过程的影响。测定了催化氧化床的平均温度分布和最小启动功率，实验考察了空速(2600h−1~11500h−1)和甲烷浓度(0.8%~1.2%)等操作条件对催化氧化床温度分布的影响。此外，还讨论了甲烷转化率和催化氧化床层的平均温度，确定了临界空速和临界甲烷浓度。
The results of experimental investigations on catalytic oxidation of coal mine ventilation air methane in a preheat catalytic reaction reactor is presented in this paper. The experimental system was located in the Energy Research Institute of Shandong University of Technology, which has been applied to investigate the effects of startup conditions such as the startup flow coefficient (0.3–0.5) and the startup power (10 kW–20 kW) on the startup process within the preheat catalytic reaction reactor. The average temperature distribution of catalytic oxidation bed and the minimal startup power were measured and the effects of operating conditions such as the space velocity (2600 h−1to 11,500 h−1) and the methane concentration (0.8%–1.2%) were experimentally investigated. Moreover, the methane conversion rate and the average temperature of the catalytic oxidation bed were discussed and the critical space velocity value and the critical methane concentration value were determined.
