摘要:

生物物质制氢由于原料资源广泛、可再生且具有全程良性循环的特征，是一种符合可持续发展战略的制氢技术。在蒸汽／空气(富氧)气化过程中，焦油的去除是关键，根据其位置可分为同步气化除焦法和两步气化除焦法，可较为有效地增加气体产率及降低焦油含量。在超临界水气化过程中，焦油含量很低，但进料浓度较低，反应条件苛刻。本文就上述方法及所用催化剂做一述评。

Abstract:

Hydrogen is an important clean energy resource and raw material for the chemical industry, the market demand of which is expanding. However, the conventional hydrogen production processes have not been able to meet the requirement of social development. B
