ABSTRACT:
The invention is directed to a method for modifying a microporous metalloaluminophosphate molecular sieve, the method comprising the steps of a) introducing a metal hydride compound within the cages of said microporous molecular sieve, and b) reacting said metal hydride compound with the acid groups located in the cages of the molecular sieve, wherein the metal hydride compound is selected from the group consisting of hydrides of metals of Groups 1 and 2 of the Periodic Table, compounds of formula M1M2H4and mixtures thereof. M1being a metal belonging to Group 13 of the Periodic Table and M2being a metal belonging to Group 1 of the Periodic Table. The invention also relates to modified metalloaluminophosphate molecular sieves, to catalyst particles containing them and the use of the modified metalloaluminophosphate molecular sieves in catalytic processes.
