煤炭地下气化中CO_2化学反应特性及影响因素

Reaction Character and Influence Factor of CO_2 in Underground Coal Gasification

从气化反应过程的热力学及动力学方面分析了地下气化中 CO2 的化学反应特性 ,总结了影响 CO2 化学反应过程的气化因素 ,并在现场试验的基础上得出了鼓风量、气化炉进水量及气化通道长度对出口煤气中 CO2

The reaction character of CO 2 in the process of underground coal gasification (UCG) was analyzed according to the thermodynamics as well as dynamics. The gasification factors influencing CO 2 reaction process were studied based on field tests. The influence of the amount of air blasting, water pouring, and the length of gasification tunnel on the CO 2 content was discussed.
