<p>This invention relates to the composition and synthesis of an Extra Mesoporous Y (or "EMY") zeolite and its use in the catalytic conversion of organic compounds. In particular, this invention relates to a Y-type framework zeolite possessing a high large mesopore pore volume to small mesopore pore volume ratio. The novel zeolite obtained provides beneficial structural features for use in petroleum refining and petrochemical processes.</p> |
