Abstract
An attrition-resistant catalyst is prepared contacting a spray dried zeolite with a modifying agent. The modifying agent is (i) a halogen-free compound hydrolyzable to an oxide selected from the group consisting of silica, alumina, titania, zirconia, niobia, and mixtures thereof; or (ii) a sol selected from the group consisting of silica, alumina, titania, zirconia, niobia, and mixtures thereof.
