Abstract
Official abstract text for this publication.
A particulate desulphurization material includes one or more copper compounds supported on a zinc oxide support material, wherein the desulphurization material has a copper content in the range 0.1 to 5.0% by weight and a tapped bulk density ≧1.55 kg/l. The material is obtained by (i) mixing a powdered copper compound with a particulate zinc support material comprising zinc oxide and one or more precursors that form zinc oxide upon calcination, and one or more binders to form a copper-containing composition, (ii) shaping the copper-containing composition by granulation, and (iii) drying and calcining the resulting granulated material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of making a particulate desulphurisation material comprising one or more copper compounds supported on a particulate zinc oxide support material, wherein the desulphurisation material is in the form of granules consisting of one or more powdered copper compounds, zinc oxide, zinc oxide formed by calcination of one or more zinc oxide precursors, and one or more binders, wherein the desulphurisation material has a copper content, expressed as CuO, in the range 0.1 to 5.0% by weight and a tapped bulk density ≧1.55 kg/l, comprising the steps of: (i) mixing one or more powdered copper compounds with a particulate zinc oxide support material comprising zinc oxide, one or more precursors that form zinc oxide upon calcination, and one or more binders to form a copper-containing composition, (ii) shaping the copper-containing composition by granulation, and (iii) drying and calcining the resulting granulated material to form the particulate desulphurization material. 2. The method according to claim 1 , wherein the copper compound in the copper-containing composition is selected from the group consisting of copper oxide, copper hydroxide, and copper hydroxycarbonate. 3. The method according to claim 1 , wherein the copper compound, zinc oxide support material, and one or more zinc oxide precursors are combined with one or more binders and granulated to form agglomerated spheres with a diameter in the range 1 to 10 mm. 4. The method according to claim 1 , wherein the copper compound, zinc oxide support material, and one or more zinc oxide precursors are combined with one or more binders and granulated to form agglomerated spheres with a diameter in the range 1.5 to 7.5 mm. 5. The method according to claim 1 , wherein the copper compound, zinc oxide support material, and one or more zinc oxide precursors are combined with one or more binders and granulated to form agglomerated spheres with a diameter in the range 2.5 to 5.0 mm.
