英文摘要	thermodynamic analysis with gibbs free energy minimization was performed for aqueous phase reforming of methanol, acetic acid, and ethylene glycol as model compounds for hydrogen production from bio-oil. the effects of the temperature (340-660 k) and pressure ratio p-sys/p-h2o (0.1-2.0) on the selectivity of h-2 and ch4, formation of solid carbon, and conversion of model compounds were analyzed. the influences of cao and o-2 addition on the formation of h-2, ch4, and co2 in the gas phase and solid phase carbon, caco3, and ca(oh)(2) were also investigated. with methanation and carbon formation, the conversion of the model compounds was >99.99% with no carbon formation, and methanation was thermodynamically favored over hydrogen production. h-2 selectivity was greatly improved when methanation was suppressed, but most of the inlet model compounds formed solid carbon. after suppressing both methanation and carbon formation, aqueous phase reforming of methanol, acetic acid and ethylene glycol at 500 k and with p-sys/p-h2o = 1.1 gave h-2 selectivity of 74.98%, 66.64% and 71.38%, respectively. these were similar to the maximum stoichiometric hydrogen selectivity of 75.00% (methanol), 66.67% (acetic acid), and 71.43% (ethylene glycol). at 500 k and 2.90 mpa, as the molar ratio of cao/bmcs increased, the normalized variation in h-2 increased and that for ch4 decreased. formation of solid carbon was effectively suppressed by addition of o-2, but this was at the expense of h-2 formation. with the o-2/bmcs molar ratio regulated at 1.0, oxidation and co2 capture increased the normalized variation in h-2 to 33.33% (methanol), 50.00% (acetic acid), and 60.00% (ethylene glycol), and the formation of solid carbon decreased to zero. copyright (c) 2011, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
