经过H_2和H_2S处理的担载铁催化剂,对于烯烃和二烯烃的加氢有着不同的活性相.通过对催化剂的程序升温还原谱和穆斯堡尔谱以及加氢反应,考察了催化剂的物相及其对烯烃加氢反应的影响;提出了铁催化剂加氢活性相的形态和生成方式.
The supported iron catalysts treated with H 2 and H 2 S have different active phases for the hydrogenation of olefins and diolefins. Through the temperature-programmed reduction and Mossbauer spectroscopy and hydrogenation reactions, the effects of catalyst phase And its effect on the hydrogenation of olefins; the morphology and formation of the active phase of the iron catalyst hydrogenation are proposed.
