Abstract
Manufacture of catalysts containing at least three essential metals consisting of copper, zinc and aluminum. The process for manufacturing the catalyst comprises the formation of homogeneous amorphous precipitate of the above-mentioned metals, followed with a washing in two steps, first with water, then with an acid solution. These catalysts are used in balanced reactions involving alcohols and synthesis gas, particularly in methanol synthesis.
