<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a hydrogenation catalyst, simpler and more efficient than a coprecipitation method, in the method of manufacturing the hydrogenation catalyst comprising copper and calcium silicate. <P>SOLUTION: Silica, a calcium compound, water, ammonia, and a copper compound are added and kneaded simultaneously or sequentially, wherein an ammonia addition amount is 30-65 wt.% with respect to the copper in the copper compound. A hydrogenation catalyst precursor obtained by drying and then firing the resultant paste at a temperature of 300-600°C is subjected to reduction treatment. <P>COPYRIGHT: (C)2013,JPO&INPIT |
