摘　　要：采用等体积浸渍的方法制备Ru/γ-Al2O3系列催化剂,进行乙酸临氢催化活性评价,考察不同担载量及不同助剂对催化剂活性的影响,对临氢催化改质机理进行讨论,并在筛选出的活性较高的CoRu/γ-Al2O3催化剂上,对生物油临氢催化改质进行研究。实验结果表明,生物油经改质后pH值由2.33上升到2.47,含水量由35.53%增加到38.55%。The Ni/γ-Al2O3 catalysts were prepared by mixing ruthenium salts and γ-Al2O3 as support. Their catalytic activities were evaluated by the hydrotreatment of model compound, acetic acid under the temperature of 200℃ and 3MPa in a stirring batch reactor. The CoRu/γ-Al2O3 catalyst exhibits the highest activity. The reaction mechanism of hydrotreatment was investigated. The hydrotreatment and esterification of bio-oil were carried out with CoRu γ-Al2O3 catalyst. The pH of bio-oil increased from 2. 33 to 2.47, and the water content increased from 35.53% to 38.55%.
