PROBLEM TO BE SOLVED: To produce simply and efficiently a transition metal-containing silicoaluminophosphate zeolite high in high-temperature hydrothermal durability.SOLUTION: A production method of a transition metal-containing zeolite which is composed of a zeolite containing silicon atoms, phosphorus atoms and aluminum atoms at least in the skeletal structure and added with a transition metal is synthesized hydrothermally from an aqueous gel comprising a silicone atom raw material, an aluminum atom raw material, a phosphorus atom raw material and a transition metal raw material and a polyamine other than diamines. The transition metal-containing silicoaluminophosphate zeolite produced by the hydrothermal synthesis from the aqueous gel containing a transition metal raw material and a polyamine, together with zeolite raw materials, shows high high-temperature hydrothermal durability and a high catalytic activity. |
