Title:
COPPER-CONTAINING CATALYST AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP2000279815
Kind Code:
A
Abstract:
To obtain a uniform crystallite distribution by using at least one material selected from an organic acid and its ammonium salt as a coprecipitation agent.
This catalyst contains 30-70 wt.% copper oxide, 30-70 wt.% zinc oxide and 0-30 wt.% alumina, does not contain sodium, and has 30-50 m2/g specific surface area, 0.10-0.25 ml/g pore volume and 10-25 nm average pore diameter. In this case, a copper-containing catalyst having a uniform crystallite distribution wherein a crystallite having under 1.0 nm diameter occupies a proportion of 0-10%, 1.0-2.0 nm crystallite occupies a proportion of 80-95% and over 2.0 nm crystallite occupies a proportion of 0-10%, can be obtained.
