Abstract

AN EX SITU SELECTIVATED CATALYTIC MOLECULAR SIEVE FOR ENHANCED SHAPE SELECTIVE HYDROCARBON CONVERSIONS IN WHICH A CATALYTIC MOLECULAR SIEVE IS MODIFIED BY BEING EXPOSED TO AT LEAST TWO SELECTIVATION SEQUENCES, EACH SEQUENCE INCLUDING AN IMPREGNATION OF THE MOLECULAR SIEVE WITH A SELECTIVATING AGENT AND A SUBSEQUENT CALCINATION OF THE IMPREGNATED MOLECULAR SIEVE. THE EX SITU SELECTIVATION METHOD IS ALSO DESCRIBED, INCLUDING THE USE OF LOW VOLATILITY ORGANIC CARRIERS FOR THE SELECTIVATING AGENT. ALSO, A METHOD FOR MODERATE STEAMING OF THE EX SITU SELECTIVATED MOLECULAR SIEVE. ALSO A METHOD FOR IN SITU TRIM-SELECTIVATING THE EX SITU SELECTIVATED CATALYTIC MOLECULAR SIEVE. ALSO DESCRIBED IS THE PROCESS FOR SHAPE SELECTIVE HYDROCARBON CONVERSION COMPRISING CONTACTING A HYDROCARBON FEEDSTREAM UNDER CONVERSION CONDITIONS WITH THE MODIFIED CATALYTIC MOLECULAR SIEVE.
