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 preselectivated by agglomerating with an organosilicon compound. The invention also includes a method for agglomeration-preselectivation and the shape selective catalyst which results from the agglomeration preselectivation.

A process for a shape selective hydrocarbon conversion comprises contacting a reaction stream comprising hydrocarbon under conversion conditions, with a catalytic molecular sieve which has been pre-selectivated by agglomerating a mixture comprising crystalline molecular sieve material and organosilicon compound.
A process for disproportionation of toluene into p-xylene comprising:
- contacting a reaction stream comprising toluene under toluene disproportionation conditions with a catalytic molecular sieve which has been pre-selectivated by agglomerating a mixture comprising crystalline molecular sieve material and an organosilicon compound.
