摘要

氢作为一种清洁能源载体,在替代化石燃料和缓解气候变化方面引起了全世界的极大兴趣。然而,目前世界上来自可再生资源的绿色氢气产量不到0.1%,这主要来自水电解,只有在使用可再生电力时才是有益的。从各种可再生资源中生产氢气是可取的。本文综述了木质生物质通过生物质蒸汽气化、生产者气体处理和H2/CO2分离制氢的最新进展。生产商气体处理包括蒸汽甲烷重整(SMR)和水煤气变换(WGS)反应,以将生产商气体中的CH4和CO转化为H2和CO2。还讨论了使用液体载体通过氢化进行H2储存的问题。研究了在SMR之前的CO2捕获,以提高SMR和WGS反应中的H2产率。

Recent advances in thermochemical conversion of woody biomass for production of green hydrogen and CO2 capture: A review

Hydrogen as a clean energy carrier has attracted great interests world-wide for substitution of fossil fuels and for abatement of the climate change concerns. However, green hydrogen from renewable resources is less than 0.1% at present in the world hydrogen production and this is largely from water electrolysis which is beneficial only when renewable electricity is used. Hydrogen production from diverse renewable resources is desirable. This review presents recent advances in hydrogen production from woody biomass through biomass steam gasification, producer gas processing and H2/CO2 separation. The producer gas processing includes steam-methane reforming (SMR) and water-gas shift (WGS) reactions to convert CH4 and CO in the producer gas to H2 and CO2. The H2 storage discussed using liquid carrier through hydrogenation is also discussed. The CO2 capture prior to the SMR is investigated to enhance H2 yield in the SMR and the WGS reactions.
