Patent ID: 7229941

Claim:
A crystalline aluminate catalyst of the pentasil type comprising primary aluminosilicate crystallites with an average diameter from about 0.01 μm to less than 0.1 μm wherein at least about 20% of the crystallites are combined to form agglomerates with a size from about 5 μm to about 500 μm, wherein the crystallites and the agglomerates are bonded together by an aluminum oxide binder, wherein the catalyst has a BET surface area from about 300 to about 600 m 2 /g and a pore volume from about 0.3 to about 0.8 cm 3 /g, and wherein, the amount of the finely divided aluminum oxide binder comprises from about 10 to about 40 wt. %, of the total weight of the aluminosilicate and binder.
