英文摘要	acids, aldehydes, ketones and phenols, which are the main components of bio-oil, have negative effects on the properties. in this paper, the mixture of acetic acid, furfural, hydroxyacetone, ethanediol, phenol and water were chosen as hybrid model compounds of bio-oil (mcb). to convert these compounds into stable and combustible oxygenated organics (alcohols and esters), one step hydrogenation-esterification (ohe) was carried out over raney ni catalyst (rn) and mo, sn, fe, cu modified raney ni catalysts (rns) in the presence of methanol. 100% conversions of furfural and hydroxyacetone were achieved over rns with high selectivity to desired products. the acetic acid conversion was only 35.1% with no methanol addition, while within 6 g/8 g methanol/mcb addition, the conversion of acetic acid increased to 81.1%. the esterification activity of alcohols was followed by methanol > tetrahydrofurfuryl alcohol (thfa), the hydrogenation product of furfural > ethanediol. among the rns, the addition of fe catalyst restrained the aqueous-phase reforming of methanol and promoted the esterification of methanol and acetic acid. the mo-rn showed the most favorable performance in the hydrogenation of phenol among the rns. but the rn modified by both fe and mo did not give a good performance. after the ohe of light fraction of raw bio-oil over mo-rn, there was no ketone & aldehyde detected and the contents of acids and phenols decreased from 49.04% and 7.35% to 8.21% and 3.84%. the conversion of acids could reach to 85.01% which was nearly to the conversion of acetic acid in mcb. the contents of alcohols and esters increased from 5.79% and 4.74% to 53.61% and 33.66%. the content of stable and combustible oxygenated organics reached to 87.27% after ohe of light fraction of raw bio-oil.
