NaBH 4低温还原的负载型镍基催化剂苯酚加氢的研究
Catalytic Performance for Phenol Hydrogenation of Nickel Supported Catalysts Reduced by NaBH 4
摘要
Abstract
Nickel-based supported catalysts on γ-Al2 O 3 or SiO 2 from Ni(NO 3 )2 ,NiCl2 and NiSO 4 were prepared by NaBH 4 reduction at low temperature.The effect of supports,nickel source,loading and reduction method on the catalytic performance of phenol hydrogenation was investigated .Among the three nickel salts,NiCl2 was the best in NaBH 4 reduction system.It was shown that in NaBH 4 reduction system the support γ-Al2 O 3 displayed better than SiO 2 .The main products of phenol hydrogenation were cyclohexanol and cyclohexanone,and the selectivity of cyclohexanol was higher on nickel supported catalysts.When the ratio of n (B)/n (Ni)was 3,the catalytic conversion of phenol hydrogenation was the highest.However, the nickel supported catalysts prepared by NaBH 4 reduction were vulnerable in high-temperature resistance.关键词
