Abstract
A method for producing a catalytically active absorber for desulphurizing hydrocarbon streams by mixing a thermally decomposable copper source, a thermally decomposable molybdenum source, zinc oxide, and water, heating the mixture to decompose the copper and molybdenum sources to produce zinc oxide loaded with copper and molybdenum, and calcining the zinc oxide, wherein the zinc oxide has a specific surface area of more than 20 m2/g and an average particle size D50 in the range of from 7 to 60 μm.
Claims11
A method for producing a catalytically active absorber for desulphurizing hydrocarbon streams, comprising the steps of:
- a) producing a mixture from:
- a thermally decomposable copper source;
- a thermally decomposable molybdenum source;
- zinc oxide;
- and
- water;
- b) heating the mixture to a temperature at which the thermally decomposable copper source and the thermally decomposable molybdenum source decomposes, with the result that a zinc oxide loaded with copper and molybdenum compounds is obtained;
- and
- c) calcining the zinc oxide loaded with copper and molybdenum compounds, wherein the catalytically active adsorber is obtained;
- wherein there is used as zinc oxide a zinc oxide with a specific surface area of more than 20 m2/g and an average particle size D50 in the range of from 7 to 60 μm.
