ABSTRACT:
A method for preparing a catalyst precursor for methanol synthesis using copper sulfate recovered from low-cost copper etching waste solution as the source of copper, which comprises using recovered copper sulfate containing the mother liquor in the amount of 10% by weight or less, and adding a zinc or aluminum compound, and, optionally, further adding a boron compound to the recovered copper sulfate. The catalyst prepared by such method has all of the characteristics of a catalyst prepared with an expensive starting material, such as conventional metal nitrates. By using such method, the catalyst cost can be reduced to a great extent, thus rendering the method of great commercial value.
