华亭煤地下气化与固定床气化指标对比研究

 摘要：对比分析了空气蒸汽连续法气化工艺条件下华亭煤现场实测所得的地下气化指标与采用综合计算法模拟得到的固定床气化指标。结果表明，固定床气化所得到的高热值气体量（如CH4、CO）大于地下气化所得量，固定床气化碳进入煤气的转化效率要高于地下气碳转化效率。推测地下气化过程中，地下水参与了气化的反应，并导致地下气化所得的氢气量大于固定床气化所得量。

Study on Index Comparison between Underground Coal Gasification in Huating Mine and Fixed Bed Coal Gasification

AbstractA comparative analysis of the gasification index which was got from site test under the technological condition of air steam method with fixed bed coal gasification index simulated by comprehensive calculation method of Huating coal, the results showed that fixed bed coal gasification produces more high heat value gas （such as CH4、CO） than underground coal gasification does，the carbon conversion entering gas of fixed bed coal gasification is higher than that of underground coal gasification，guessing that underground water participates in underground coal gasification and underground gasification produces more hydrogen than fixed bed gasification does because of underground water.
