Abstract: In this paper, La-Ni-Mo-B and La-Co-Mo-B amorphous catalysts were prepared by the chemical reduction method and their hydrodeoxygenation （HDO） activities were determined by using benzaldehyde and acetophenone as model compounds. The results showed that La-Ni-Mo-B and La-Co-Mo-B had amorphous structure and both conversion and deoxygenation rate reached to 100.0% on these two catalysts. The deoxygenation products such as toluene or ethylbenzene could be further hydrogenated to the corresponding cycloalkanes on La-Ni-Mo-B amorphous catalyst because of its high hydrogenation activity due to electron transfer between Ni0 and B0, leading to low aromatic content in the product, which met the demand of clean fuel.

摘要： 采用化学还原法制备出La-Ni-Mo-B和La-Co-Mo-B非晶态催化剂，以苯甲醛和苯乙酮为模型化合物研究了所制催化剂的加氢脱氧性能。结果表明，两种催化剂都具有非晶态结构，催化原料的转化率和脱氧率都能达到100.0%。因La-Ni-Mo-B中Ni0和B0之间存在电子转移，使其具有较高的加氢活性，脱氧后产物中的甲苯或乙苯可被进一步加氢生成相应的环烷烃，产物中的芳烃含量低，满足清洁燃油的要求。
