ABSTRACT:
A process for shape selective hydrocarbon aromatization that involves contacting a hydrocarbon feedstream, under aromatization conditions, with a catalytic molecular sieve which has been modified by being ex situ selectivated with a silicon compound. The ex situ selectivation involves exposing the catalytic molecular sieve to at least two selectivation sequences, each sequence comprising contacting the catalytic molecular sieve with a silicon compound followed by calcination. Optionally, the modified catalytic molecular sieve may be further selectivated in situ.
