Structurally enhanced cracking catalysts

A cracking catalyst contains about 5%-50% size of a substantially inert core containing mullite and 50%-95% size of an active shell containing NaY zeolite catalyst and matrix, wherein the NaY zeolite catalyst is spray dried to contain mullite microsphere, NaY zeolite precursor and matrix precursor a...

Beschreibung
Zusammenfassung:	A cracking catalyst contains about 5%-50% size of a substantially inert core containing mullite and 50%-95% size of an active shell containing NaY zeolite catalyst and matrix, wherein the NaY zeolite catalyst is spray dried to contain mullite microsphere, NaY zeolite precursor and matrix precursor and is crystallized in the active shell, and the zeolite catalyst has at least 100m /g of superficial area.
