摘要：随着煤制天然气项目的不断上马，国内许多城市将有煤制天然气接入城市管网。煤制天
然气绝大部分为甲烷并含少量氢气以及其它微量组分，属于合成天然气的一种，成分与常规天然气存在一定的区别。因此，在煤制天然气接入城市管网时会对下游用户造成一定影响。通过对比含氢量3%和10%的煤制天然气与城市常规天然气的成分及理化特征差别，采用华白数法、A.G.A.指数法分析该煤制天然气对居民燃气用具的影响，理论分析认为含氢量在10%以内的煤制天然气对居民燃气用具的燃烧影响不大，但是会增加燃气使用量。通过部分实验，实验结果与理论分析结果相符。

Abstract:With the continuous construction of coal to synthetic natural gas projects,coal to synthetic
natural gas was accessed to urban gas pipeline network in many domestic cities. Coal to synthetic natural gas belongs to an artificial gas, whose ingredient is methane accounted for most and hydrogen accounted for small parts which have some differences properties with conventional natural gas. Therefore, some impacts will be caused when coal to synthetic natural gas is pumped into urban gas pipeline network. The comparison of compositions and physical and chemical characteristics between coal to synthetic natural gas whose hydrogen content was 3% and 10% respectively.Simultaneously,wobbe number method and A.G.A. index method were adopted to analyze the impact of the coal and natural gas on resident gas cooking appliances Through theoretical analysis, it is concluded that coal to synthetic natural gas whose hydrogen content within 10% had little impact on combustion of resident gas cooking appliances, but would increase gas usage quantity. Part of the experimental research was finished, experimental results and theoretical analysis results were in agreement.
