ABSTRACT: Aqueous phase reforming (APR) of biomass derived feedstock producing
hydrogen was reviewed. The APR process was discussed based on different
feedstock categories such as sugars, polyols and ethanol. The mechanism of APR
was analyzed referring to different structures of feedstock. The reaction
pathways of APR were investigated. The usage of catalysts should be judged by
feedstock on the requirement including C-C bond cleavage, water-gas shift (WGS)
reaction, and catalyst maintenance. The prospects were concluded based on the
recent works from bimetallic catalysts and high efficient supports. Examples of
significant challenges of reducing catalyst cost and increasing catalyst
stability have been discussed. The modification and utilization of alkane selectivity of APR processes for liquid fuel production was also investigated.
