摘要乙酸加氢制备乙醇催化剂及其制备过程。在一个实施方案中:催化剂至少需要一种基本的金属,一种火成石英载体,一种硅酸盐助剂。该金属优先选择铜、铁、钴、镍、钌、铑、钯、锇、铱、铂、钛、锌、铬、铼、钼、钨中的一种。除此之外,催化剂也最好可包含另一种不同于第一种金属的金属,包括:铜、钼、锡、铬、铁、钴、钒、钨、钯、铂、镧、铈、锰、钌、铼、金、镍。 Abstract Hydrogenation of acetic acid to ethanol catalyst and its preparation process. In one embodiment: the catalyst requires at least one base metal, a pyrochlore support, a silicate builder. The metal is preferably one of copper, iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium, platinum, titanium, zinc, chromium, rhenium, molybdenum and tungsten. In addition, the catalyst may also preferably contain another metal other than the first metal, including copper, molybdenum, tin, chromium, iron, cobalt, vanadium, tungsten, palladium, platinum, lanthanum, cerium, , Ruthenium, rhenium, gold, nickel.
