ABSTRACT:
A process for shape selective hydrocarbon conversion involves contacting a hydrocarbon feedsteam under conversion conditions with a modified catalytic molecular sieve which has been modified by being pre-selectivated with a first silicon source, then steamed. The feedstream may also contain a second silicon source which is a high efficiency para-xylene selectivating agent. The method for modifying the molecular sieve is also described.
