摘要： 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.

摘要： A methanol synthesis process comprising reacting a methanol synthesis gas composition in the presence of a methanol synthesis catalyst. The methanol synthesis catalyst is a catalyst produced by drying and sintering a catalyst precursor. The catalyst precursor is produced from a copper compound, a zinc compound, an aluminum compound and a boron compound, by (a) precipitating from an aqueous reaction mixture comprising a copper sulfate which is recovered from a copper etching waste solution mother liquor, the copper sulfate comprising up to 10% by weight of said mother liquor, with a precipitant, the precipitant being in an amount of 1-fold to 2-fold equivalent of the copper sulfate, the precipitating being carried out in the presence of the boron compound, the boron compound being a water soluble boron compound, and mixing therewith the zinc compound, without separation, to form a precipitate in the reaction mixture, (b) filtering the reaction mixture from step (a) to form a cake, (c) washing the cake from step (b) with an aqueous alkali solution in a concentration of 0.01 to 0.5 weight % and then washing with water, (d) adding the aluminum compound to the washed cake of step (c), (e) kneading the resulting mixture from step (d) and (f) drying the resulting kneaded mixture from step (e).
