| 英文摘要 | High amounts of acid compounds in bio-oil not only lead to the deleterious properties such as corrosiveness and high acidity, but also set up many obstacles to its wide applications. by hydrotreating the bio-oil under mild conditions, some carboxylic acid compounds could be converted to alcohols which would esterify with the unconverted acids in the bio-oil to produce esters. the properties of the bio-oil could be improved by this method. in the paper, the raw bio-oil was produced by vacuum pyrolysis of pine sawdust. the optimal production conditions were investigated. a series of nickel-based catalysts were prepared. their catalytic activities were evaluated by upgrading of model compound (glacial acetic acid). results showed that the reduced mo-10ni/gamma-al2o3 catalyst had the highest activity with the acetic acid conversion of 33.2%. upgrading of the raw bio-oil was investigated over reduced mo-10ni/gamma-al2o3 catalyst. after the upgrading process, the ph value of the bio-oil increased from 2.16 to 2.84. the water content increased from 46.2 wt.% to 58.99 wt.%. the h element content in the bio-oil increased from 6.61 wt.% to 6.93 wt.%. the dynamic viscosity decreased a little. the results of gc-ms spectrometry analysis showed that the ester compounds in the upgraded bio-oil increased by 3 times. it is possible to improve the properties of bio-oil by hydrotreating and esterifying carboxyl group compounds in the bio-oil.
