回顾了国内外超临界水生物质气化(SCWG)制氢的研究进展.生物质在超临界水条件下能够转化为氢气,主要优点是湿生物质不必干燥就可以进行相关反应且氢气是高压下直接生成的,意味着所需的反应器容积较小且用来压缩产气的能量较少.用来加热大量水的能量可以通过热交换器回收,提高系统的能量效率.各参数如温度、压力、催化剂活性和生物质,水比等因素的影响被讨论.

Previous works relating to biomass gasification in supereritical water for hydrogen production were reviewed.Converting biomass into hydrogen could be accomplished in supereritical water,the main advantage of which was that wet biomass could be convened without drying first and the hydrogen was produced at hJish pressure directly,that resulted a smaller reactor volume and lower energy requirement for compressing the gas into the storage tank.The energy used to heat the large amount of water can be reccovered through the heat exchanger to improve the energy efficiency of the system.Effects of various parameters such as temperature,pressure,catalyst activity and biomass/water ratio were also discussed.
