  • Catalyst for the synthesis of methanol and a method for the synthesis of methanol
    Patent number: 6342538
    Abstract: An object of the present invention is to offer a catalyst for the hydrogenation which is suitable for the synthesis of methanol from CO and/or CO2 under the condition of low temperature and low pressure. In the said catalyst, Pd having a particle size of 5 nm or less is carried on a cerium type oxide (CeO2) whereby methanol is synthesized by the reaction of CO and/or CO2 with hydrogen. The said catalyst for the hydrogenation can be manufactured by a method where the catalyst is manufactured from a coprecipitate of a precursor of cerium type oxide and palladium and a method where palladium is separated in a cerium type oxide.
