HYDROGENATION AND ETHYNYLATION CATALYSTS

A process for preparing a catalyst includes impregnating a metal oxide carrier with an aqueous solution to form an impregnated carrier; drying the impregnated carrier to form a dried, impregnated carrier; and heat-treating the dried, impregnated carrier in air to form the catalyst, wherein: the aqueous solution includes a copper salt; and from about 3 wt% to about 15 wt% of a C3-C6 multifunctional carboxylic acid; and the catalyst includes from about 5 wt% to about 50 wt% copper oxide. 一种用于制备催化剂的方法包括：用水溶液浸渍金属氧化物载体以形成所浸渍的载体；将所述浸渍载体干燥以形成干燥的浸渍载体；以及在空气中对所述干燥的浸渍载体进行热处理以形成所述催化剂；其中：所述水溶液包括铜盐；以及约3wt％到约15wt％C3-C6多官能羧酸；且所述催化剂包括约5wt％到约50wt％氧化铜。
