PHOSPHORUS OXIDE-CONTAINING METAL-SUPPORTED CRYSTALLINE SILICO-ALUMINO PHOSPHATE MOLDING CATALYST AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a phosphorus oxide-containing metal-supported crystalline silico-alumino phosphate molding catalyst which has excellent low-temperature hydrothermal stability and high activity even in a region where reaction temperature is low.

SOLUTION: The phosphorus oxide in a phosphorus oxide-containing metal-supported crystalline silico-alumino phosphate particle constituting the molding catalyst is derived from orthophosphate and/or pyrophosphate. When the phosphorus oxide is derived from the orthophosphate, the content of the phosphorus oxide is within 2-20 wt.% in terms of P2O5and when the phosphorus oxide is derived from the pyrophosphate, that of the phosphorus oxide is within 2.5-25 wt.% in terms of P2O7.
