ABSTRACT:
A process for treating crystalline aluminophosphates to provide aluminophosphates having modified catalytic properties. The crystalline aluminophosphates are contacted with a halogen-derived compound at an effective temperature and for an effective time to alter the surface characteristics of the aluminophosphates with resulting modification of catalytic properties.
