摘要
Abstract
Al2O3 support was prepared using aluminum hydroxide as precursor and catalyst was prepared using MgO as structural promoter and Ni as active component.The catalyst was characterized by XRD,N2 adsorption-desorption,H2-TPR,and mercury intrusion methods,and evaluated using 4-tert-butylphenol as raw material and isopropanol as solvent in a fixed bed reactor.The effects of Ni loading,reaction temperature,reaction pressure and LHSV on the selective hydrogenation of 4-tert-butylphenol were investigated,and the stability of the catalyst was also investigated.The experimental results show that the hydrogenation performance of the catalyst is the best when Ni loading is 30％(w).The optimal reaction conditions are obtained as follows:reaction temperature 160 ℃,LHSV 2.5 h-1,and reaction pressure 2 MPa.Under the conditions,the conversion of 4-tert-butylphenol can reach 96.39％,and the selectivity to 4-tert-butylcyclohexanol can reach 95.68％.In the process of continuous reaction for 300 h,the stability of the catalyst is good.关键词
