Abstract
A method is provided for producing an aluminosilicate catalyst. The method includes a first phosphorus treatment step of treating a crystalline aluminosilicate with a first phosphorus compound, a mixing and firing step of mixing the phosphorus-treated crystalline aluminosilicate obtained in the first phosphorus treatment step with a binder and then performing firing to form an aluminosilicate mixture, and a second phosphorus treatment step of treating the aluminosilicate mixture with a second phosphorus compound.
