沼气制氢工艺技术研究

Research on Hydrogen Production Process from Biogas

沼气是一种主要成分为甲烷和二氧化碳的混合气,氢能是未来的关键清洁能源载体,以沼气为原料制取的氢气是绿色清洁可再生能源。将沼气首先提纯为生物甲烷,再以生物甲烷蒸汽转化制氢两步过程均有成熟的商业化技术,但是工艺路线较长。将甲烷蒸汽转化技术加以调整,直接以沼气为原料蒸汽转化制氢,可以简化工艺路线,同时该路线技术和经济上都是可行的,具有现实意义。

Biogas is a mixture of methane and carbon dioxide.Hydrogen energy is the key carrier of clean energy in the future.Hydrogen produced from biogas is a green,clean and renewable energy.There are mature commercial technologies in the two-step process of purifying biogas into biomethane and then converting biomethane into hydrogen,but the process route is long.Adjusting the steam conversion technology of methane to produce hydrogen directly from biogas can simplify the process route,which is technically and economically feasible and has practical significance.
