Abstract
Disclosed are improved HAMS-1B crystalline molecular sieve-based catalyst compositions made by impregnating such a sieve, which has been incorporated in an inorganic matrix, with a small amount of a magnesium compound, and a process for employing such catalyst compositions for the methylation of a xylene in which the amount of pseudocumene in the product is substantially enhanced compared to that produced by the unimpregnated catalyst composition.
