<P>PROBLEM TO BE SOLVED: To provide an aluminum phosphate-modified metal-supported crystalline silica aluminophosphate catalyst having an excellent hydrothermal stability, maintaining a high activity for a long period of time and having, especially, an excellent low temperature activity; and a production method for the same. <P>SOLUTION: In the aluminum phosphate-modified metal-supported crystalline silica aluminophosphate catalyst, the surface of the metal-supported crystalline silica aluminophosphate particles is modified by aluminum phosphate, and the content of aluminum phosphate in the catalyst is within the range of 0.1 to 40 wt.% when the aluminum phosphate is given as Al<SB>2</SB>O<SB>3</SB>+P<SB>2</SB>O<SB>5</SB>based on the metal-supported crystalline silica aluminophosphate particles. <P>COPYRIGHT: (C)2011,JPO&INPIT |
