Abstract
A process for manufacturing methanol is herein disclosed which comprises the step of reacting hydrogen with carbon monoxide and/or carbon dioxide in the presence of a synthetic catalyst obtainable by mixing, in a slurry state, (a) a beforehand prepared precipitation slurry of copper and zinc, with (b) an alumina precursor separately prepared from a water-soluble aluminum salt and a basic precipitant, to obtain a composition containing copper, zinc and aluminum, and washing, drying and then calcining the composition. A process for manufacturing the above-mentioned catalyst is also disclosed. According to the present invention, methanol can extremely efficiently be manufactured, and the catalyst having a high activity and an excellent heat resistance can also be manufactured.
