摘要
采用化学还原法制备了 Co- B超细非晶催化剂 ,借助 XRD、SEM、比表面测定等技术研究了催化剂的物相、粒子大小与形貌、比表面积及大豆油加氢活性。结果表明 ,Co- B催化剂外貌呈非晶特有的绵絮状 ,一次颗粒平均尺寸约 2 5 nm;其大豆油加氢活性远高于 Raney-
The ultrafine amorphous Co-B catalyst is prepared by chemical reduction method.XRD,SEM and specific surface area measurement techniques are used to investigate the phase,morphology,particle size and catalytic activity of the catalyst for the hydrogenation of soybean oil.The results indicate that catlyst has an average particle size of 25nm with sponge-shaped,which is amorphous special morphology,whose hydrogenation activity of soybean oil is atrikngly higher than that of Raney Ni.
