The amorphous structure of the catalyst make itself exhibited a high catalytic activity in the hydrogenation of 4-ethylbenzoic acid, 4-pentylphenol and nitrobenzene. In the case of 4-pentylphenol and 4-ethylbenzoic acid, the hydrogenation conversions were 95%, 67% respectively, at 160 ℃ and hydrogen pressure of 6.0 MPa, while for nitrobenzene, the conversion was 100% at the same temperature under 4.0 MPa H 2.展开更多
