Abstract:
Ni-based catalysts supported on di erent supports (α-Al2O3,γ-Al2O3, SiO2, TiO2, and ZrO2) were prepared by impregnation. Effects of supports on catalytic performance were tested using hydrodeoxygenation reaction (HDO) of anisole as model reaction. Ni/α-Al2O3 was found to be the highest active catalyst for HDO of anisole. Under the optimal conditions, the anisole conversion is 93.25% and the hydrocarbon yield is 90.47%. Catalyst characteriza-tion using H2-TPD method demonstrates that Ni/α-Al2O3 catalyst possesses more amount of active metal Ni than those of other investigated catalysts, which can enhance the cat-alytic activity for hydrogenation. Furthermore, it is found that the Ni/α-Al2O3 catalyst has excellent repeatability, and the carbon deposited on the surface of catalyst is negligible.

摘要:
通过化学沉淀法制备了以α-Al2O3、γ-Al2O3、SiO2,TiO2和ZrO2为载体的五种镍基催化剂,以苯甲醚为模型化合物对催化剂进行活性评价,考察载体对加氢脱氧催化反应的影响。实验表明,Ni/α-Al2O3对苯甲醚加氢脱氧反应的催化活性最高。在优化的工况下,苯甲醚的转化率达到93.25%,碳氢化合物收率达到90.47%。H2-TPD测试表明五种镍基催化剂中,Ni/α-Al2O3表面拥有更多的活性金属位,具有更高的加氢催化活性。Ni/α-Al2O3催化剂具有优异的可重复使用性能,反应后催化剂表面的积碳量几乎可以忽略.
