An aluminum phosphate-modified metal-supported crystalline silicoaluminophosphate NOx-reducing catalyst includes metal-supported crystalline silicoaluminophosphate particles having a surface modified with aluminum phosphate.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aluminum phosphate-modified metal-supported crystalline silicoaluminophosphate NOx-reducing catalyst, comprising: metal-supported crystalline silicoaluminophosphate particles having aluminum phosphate on a surface of the particles, the content of aluminum phosphate in the catalyst being 0.1 to 40% by weight in terms of Al 2 O 3 +P 2 O 5 based on the metal-supported crystalline silicoaluminophosphate particles. 2. The aluminum phosphate-modified metal-supported crystalline silicoaluminophosphate NOx-reducing catalyst according to claim 1 , wherein the value of x in (Al 2 ) X .(PO 4 ) 3 representing the aluminum phosphate is 0.1 to 3. 3. The aluminum phosphate-modified metal-supported crystalline silicoaluminophosphate NOx-reducing catalyst according to claim 1 , wherein the crystalline silicoaluminophosphate particles are at least one member selected from the group consisting of SAPO-5, SAPO-11, SAPO-34, and SAPO-37. 4. The aluminum phosphate-modified metal-supported crystalline silicoaluminophosphate NOx-reducing catalyst according to claim 1 , wherein the crystalline silicoaluminnphosphate is SAPO-34. 5. The aluminum phosphate-modified metal-supported crystalline silicoaluminophosphate NOx-reducing catalyst according to claim 1 , wherein the supported metal is a metal of an element selected from the group 8, 9, 10, 11, and 12 elements of the periodic table or a mixture thereof (including an alloy). 6. The aluminum phosphate-modified metal-supported crystalline silicoaluminophosphate NOx-reducing catalyst according to claim 1 , wherein the amount of the metal supported is in a range of 0.1 to 10% by weight in terms of metal.
