摘　　要：超临界水褐煤气化可以利用褐煤高含水率的特点,实现对褐煤的高效气化。本文拟用气相色谱法对该过程产生的气体产物进行监测分析,得到各种气体的产量和含量,讨论气体产物是否会对环境产生污染。结果表明,超临界水褐煤气化的主要气体产物是H_2、CH_4、CO、CO_2四种,该技术能够实现褐煤的高效气化。H_2、CH_4、CO都是能源气体,其燃烧产物清洁,CO_2是很好的工业气体用品,超临界水褐煤气化产生的气体不会对环境产生污染。The supercritical water gasi? cation can directly deal with the high content of water lignite without drying to realize high gasification efficiency of lignite. This article used the method of GC to analyze the gas product of supercritical water gasifi cation of lignite. The gas content and yield were quantified and the possibilities of environment pollution of these gas were discussed. The product gas was composed of H_2,CO_2,CO,and CH_4. The technology could realize high gasification efficiency of lignite. H_2、CH_4、CO were allclean energy gas. CO_2 was an important industrial product. The gas product of supercritical water gasi? cation of lignite would not cause environment pollution.
