Abstract 1. AN IMPROVED ALKYLATION PROCESS WHICH COMPRISES CONTACTING A PARAFFIN-CONTAINING HYDROCARBON FEED WITH AN OLEFIN IN THE PRESENCE OF A CRYSTALLINE ALUMINOSILICATE ZEOLITE-CONTAINING CATALYST WHICH HAS BEEN ACTIVATED BY THE FOLLOWING SEQUENTIAL STEPS: (A) BASE EXCHANGING SAID CRYSTALLINE ALUMINOSILICATE ZEOLITE WITH A SOLUTION CONTAINING AMMONIUM IONS; (B9 HEATING THE ZEOLITE PRODUCT OF STEP (A) IN THE PRESENCE OF WATER VAPOR, AT TEMPERATURES IN THE RANGE OF 600* TO 1200* F; (C) BASE EXCHANGING THE ZEOLITE PRODUCT OF STEP (B) WITH A SOLUTION CONTAINING IONS SELECTED FROM THE GROUP CONSISTING OF AMMONIUM IONS, HYDROGEN IONS AND MIXTURES THEREOF TO REDUCE THE ALKALI METAL CONTENT TO A LEVEL OF 0.02 TO 1.0% BY WEIGHT; AND (D) CALCINING THE ZEOLITE PRODUCT OF STEP (C) IN AIR AT ELAVATED TEMPERATURES.
