基于焦炉煤气低温换热式甲烷化工艺进行试验,考察了其核心装置低温换热式甲烷化反应器在甲烷化过程中的运行情况。试验结果表明,该反应器在升温过程中控温精确;在连续1 000 h运行过程中,装置运行平稳,反应器出口气组成稳定,其中出口气中CO_2转化率大于98.0%,CO转化率大于99.8%,能够一步完成焦炉煤气甲烷化反应。同时,该反应器可在负荷为1 650~1 900 m~3/h下稳定运行。

Based on the low temperature heat exchange methanation process of coke oven gas, the operation of the low temperature heat exchange methanation reactor in its core unit during methanation was investigated. The experimental results showed that the temperature of the reactor was accurate during the heating process. During the continuous operation of 1000 h, the unit ran smoothly and the outlet gas composition of the reactor was stable. The conversion rate of CO_2 in outlet gas was more than 98.0% 99.8%, one step to complete the coke oven gas methanation reaction. In the meantime, the reactor can operate stably under the load of 1 650 ~ 1 900 m ~ 3 / h.
