Patent ID: 8623927

Claim:
A method for synthesizing methanol from synthesis gas comprising: using a catalyst for methanol synthesis which comprises a Cu—Zn—Al oxide or Cu—Zn—Al—Zr oxide incorporated with a cerium-zirconium oxide having a metal weight ratio maintained at 0.02<Ce/Zr<0.5 as an admixture, wherein the catalyst for methanol synthesis is prepared by preparing a cerium-zirconium oxide having a specific surface area of 100-300 m2/g by a sol-gel process to provide an admixture for a methanol synthesis catalyst; and adding a metal mixture of a copper precursor, zinc precursor and an alumina precursor, and a basic precipitating agent to aqueous suspension containing the cerium-zirconium oxide, carrying out co-precipitation in an aqueous solution with a pH of 7-8 and aging the resultant precipitate, followed by filtering and washing, and calcining the precipitate at a temperature of 200-600° C.
