Abstract
The subject invention comprises a hydrocarbon-conversion process using a zeolitic catalyst comprising very low concentrations of non-zeolitic material and featuring a gradient in crystallinity decreasing from the outer portion to the center and an intrusion pore volume of at least 0.6 cc/gram. The catalyst is particularly effective in a xylene-isomerization process comprising ethylbenzene conversion.
