沼气重整制氢气相色谱分析方法

GC Analysis Method of Biogas Reforming to Hydrogen

生物质经厌氧发酵产生的沼气富含甲烷与二氧化碳,两者都是主要的温室气体,然而经适当净化后,沼气又是可再生的清洁能源,可以通过重整制取氢气。本文通过试验测试建立了气相色谱对沼气制氢气体的分析方法:GC7890 II型气相色谱仪、热导检测器、色谱柱为Ф3 mm×3 m不锈钢TDX-01柱、氩气(Ar)作载气、载气流速为25 mL/min,气化室与柱室温度为150℃、检测器温度为180℃,桥流为60 A。

Biogas produced by anaerobic fermentation of biomass is enriched methane and carbon dioxide,which are main greenhouse gases.However,biogas is a reproducible clean energy sources after being purified,and can produce hydrogen by catalytic reforming.Gas chromatogram analysis method for biogas reforming was established using GC7890 II,heat-transmitted detector,Ф3 mm×3 m stainless steel TDX-01 chromatogram columniation,and Ar as carried gas,velocity of the carried gas flow was 25 mL/min,temperature of gasification room and chromatogram columniation room was 150℃,temperature of detector was 180℃,bridge current was 60 A.
