氢作为使用燃料电池发电和用于运输的最清洁的燃料受到极大关注。生物质可以通过两种不同的策略热化学转化为氢气：（1）气化，然后变换转化，和（2）生物质的快速热解，然后催化蒸汽重整和特定馏分的变换转化。本文介绍了后一种途径。该方法开始于生物质的快速热解以产生生物油，生物油（作为整体或其选定的馏分）可以通过催化蒸汽重整随后通过变换转化步骤转化为氢气。这种方法已被证明在实验室规模使用模型化合物和白杨油的水馏分与商业镍基蒸汽重整催化剂。氢产率高达85%的化学计量值已获得。初始催化剂活性可通过经由含碳沉积物的蒸汽或二氧化碳（CO2）气化的周期性再生来保持。
Hydrogen is of great interest as the cleanest fuel for power generation using fuel cells and for transportation. Biomass can be thermochemically converted to hydrogen via two distinct strategies: (1) gasification followed by shift conversion, and (2) fast pyrolysis of biomass followed by catalytic steam reforming and shift conversion of specific fractions. This paper presents the latter route. The process begins with fast pyrolysis of biomass to produce bio-oil, which (as a whole or its selected fractions) can be converted to hydrogen via catalytic steam reforming followed by a shift conversion step. Such a process has been demonstrated at the bench scale using model compounds and the aqueous fraction of poplar oil with commercial nickel-based steam-reforming catalysts. Hydrogen yields as high as 85% of the stoichiometric value have been obtained. Initial catalyst activity can be maintained through periodic regeneration via steam or carbon dioxide (CO2) gasification of the carbonaceous deposits.
