Transition-metal-containing zeolite |
摘要 |
A transition-metal-containing silicoaluminophosphate zeolite having excellent high-temperature hydrothermal durability is easily and efficiently produced. A method for producing a transition-metal-containing zeolite that contains a silicon atom, a phosphorus atom, and an aluminum atom in at least its framework structure includes hydrothermal synthesis using an aqueous gel containing a silicon atom raw material, an aluminum atom raw material, a phosphorus atom raw material, a transition metal raw material, and a polyamine (other than diamines). A transition-metal-containing silicoaluminophosphate zeolite produced by hydrothermal synthesis using a zeolite raw material and the aqueous gel containing the transition metal raw material and the polyamine has excellent high-temperature hydrothermal durability and high catalytic activity. |

1. A method for producing a transition-metal-containing zeolite that contains at least a silicon atom, a phosphorus atom, and an aluminum atom in its framework structure, comprising: hydrothermal synthesis using an aqueous gel containing a silicon atom raw material, an aluminum atom raw material, a phosphorus atom raw material, a transition metal raw material, and a polyamine (other than diamines), wherein the polyamine has a general formula of H2N—(CnH2nNH)x—H (wherein n denotes an integer in the range of 2 to 6, and x is 3 or 4). |
