超细非晶态N iCoB合金催化剂的制备及其对大豆油加氢活性研究

Preparation of ultrafine amorphous NiCoB alloys and their activities for the hydrogenation of soybean oil

A series of ultrafine amorphous NiCoB alloys was prepared by chemical reduction method.XRD,TEM and BET techniques were used to investigate the phase,morphology,particle size and activity of the catalyst for the hydrogenation of soybean oil.The results indicated that their activities are higher than that of Raney Ni,Moreover,with the increasing of Ni/Co molar ration,the catalytic activity of the catalysts versus Ni/Co ration passe through a maximum at Ni/Co=0.5,at which the grain size and specific surface area were 20nm and 46.9m2·g-1,respectively.As an high effective environmental amicable catalyst,ultrafine amorphous NiCoB alloys can be used to the hydrogenation of soybean oil.
