研究了在各种共沉淀的镍催化剂上 CO和 H_2的反应,而镍催化剂在工业上常用来生产烃,特别是甲烷。尽管有很多关于由负载于金属氧化物上的镍、铂或铑催化 CO 加氢的报道,但直到最近发现在镍基催化剂上由CO 和 H_2能有效地制备如乙醇和丙醇之类的高级醇之前,还没有发现关于在镍催化剂上制备高级醇的任何报道。用碳酸钠共沉淀法来制取催化剂样品。沉淀物在353K 下老化2小时,然后用蒸馏水
The reaction of CO and H 2 over various coprecipitated nickel catalysts was studied, while nickel catalysts are commonly used industrially to produce hydrocarbons, especially methane. Although there are many reports of catalytic hydrogenation of CO catalyzed by nickel, platinum or rhodium supported on metal oxides, until recently it has been found that CO and H 2 can be efficiently produced on nickel-based catalysts by advanced techniques such as ethanol and propanol Before the alcohol, no reports on the preparation of higher alcohols on nickel catalysts have been found. Catalyst samples were prepared by sodium carbonate coprecipitation. The precipitate was aged for 2 hours at 353K and then distilled water
