Abstract

PURPOSE: To improve catalytic performance by adding a precursor component selected from among hydroxy acid such as silicon, boron or chromium and its salts to each precursor component of copper oxide, zinc oxide, zirconium oxide and/or aluminum oxide, in a methanol synthesis catalyst.

CONSTITUTION: Each precursor component of copper oxide and zinc oxide, and each precusor component of zirconium and/or aluminum oxide are used as ingredients, and at least, one type of each precursor component selected from hydroxy acid such as silicon, boron, chromium, vanadium, magnesium or phosphorus and its salts, if necessary. In addition, 30 wt.% of CO₂ as a reduced weight is added. Further, the content of zirconium and/or aluminum is 80 wt.% max in terms of an oxide. Finally CO₂ is allowed to be added to the precursor by using a sedimentation agent containing a carbonic acid product.
