Abstract
A process for a shape selective hydrocarbon conversion such as toluene disproportionation involves contacting a reaction stream under conversion conditions with a catalytic molecular sieve which has been pre-selectivated and concurrently activated by contact with a substantially aqueous solution of an organosilicon compound. The invention also includes a method for concurrently preselectivating and activating a catalyst and the shape selectivated, activated catalyst which results from this method.
Claims28
A process for a shape selective hydrocarbon conversion comprises contacting a reaction stream comprising hydrocarbon to be converted, under conversion conditions, with a molecular sieve catalyst which has been preselectivated and activated by treating with a substantially aqueous solution of a water-soluble organosilicon compound.
The process of claim 8 wherein the matrix material comprises silica.
A process for disproportionation of toluene to xylene comprising:
- contacting a reaction stream which comprises toluene, under reaction conditions for converting toluene to p-xylene, with a molecular sieve catalyst wherein the molecular sieve catalyst has been preselectivated and activated by treating with a substantially aqueous solution of a water-soluble organosilicon compound.
