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。

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.
