用化学沉积法制备了负载型非晶催化剂Co-P/SiO_2。其非晶性质由X射线衍射和差热分析鉴定,组成用ICP方法分析。测定了它对苯乙烯的加氢活性,并与相应的晶态Co-P/SiO_2及Co/SiO_2催化剂进行了对比。在高真空程序升温脱附及反应装置上研究了氢、一氧化碳的吸附及反应,提出了非晶Co-P/SiO_2催化剂上一氧化碳加氢的机理。
The supported amorphous catalyst Co-P / SiO 2 was prepared by chemical deposition. Its amorphous nature was identified by X-ray diffraction and differential thermal analysis, and its composition was analyzed by ICP method. The hydrogenation activity of styrene was measured and compared with the corresponding crystalline Co-P / SiO 2 and Co / SiO 2 catalysts. The adsorption and reaction of hydrogen and carbon monoxide were studied on high temperature vacuum desorption and desorption plant. The mechanism of hydrogenation of carbon monoxide on amorphous Co-P / SiO 2 catalyst was proposed.
