在由合成气可能得到的产品中,人们最愿意选择1,2-乙二醇(EG),因为它的氧化结构有利于达到较大的产品/原料重量比。因此,合成气直接转化成 EG 是近年来一个重要的研究课题。众所周知,由钴、钌和铑可制得有效的催化剂。早年对钴催化剂的研究因其需要高压而受到限制。与钴催化剂相比,直接转化合成气用钌催化剂更为有效。然而,钌催化 Among the products that may be obtained from syngas, one is most likely to choose 1,2-ethanediol (EG) because of its oxidative structure that facilitates greater product / feedstock weight ratios. Therefore, the direct conversion of syngas to EG is an important research topic in recent years. It is well known that effective catalysts can be made from cobalt, ruthenium and rhodium. Early research on cobalt catalysts was limited by the need for high pressures. The direct conversion of synthesis gas to ruthenium catalysts is more effective than cobalt catalysts. However, ruthenium catalyzes
