摘要

The bio-oil derived from pyrolysis of straw can be selectively converted into high-purity hydrogen by coupling three steps:(i) steam reforming(SR) of different bio-oils,(ii) water-gas shift(WGS),and (iii) the removal of CO2.The catalytic SR reaction over the NiLaTiA1 catalyst,coupled with a low-temperature WGS reaction with the CuZnA1 catalyst,promoted the conversion of various oxygen-containing organic compounds in the bio-oil into hydrogen and carbon dioxide.Under the optimized condition,light bio-oil achieved the highest conversion(99.8％,molar fraction),with a high hydrogen yield of 16.4％(mass fraction) and a H2 purity of 99.94％(volume fraction).The carbon deposition on the NiLaTiA1 catalyst was the main factor caused catalyst deactivation.Production of hydrogen from different bio-oil model compounds was also investigated in detail.
