Hybrid catalysts containing a microporous zeolite and a mesoporous cocatalyst, for the conversion of hydrocarbons or other organic compounds

Abstract From the Canadian patent

There is provided a novel hybrid catalyst suitable for the conversion of hydrocarbons and other organic compounds. The catalyst comprises 70 wt % to 85 wt % of microporous zeolite-type particles embedded in 10 wt % to 30 wt % of larger mesoporous solid particles the latter, being used as a cocatalyst. Optionally up to about 20 wt% of an inert, clay binder may be used. Preferably the zeolite-type particles are, particles having the ZSM-5 structure and in the acidic form. Also preferably, the mesoporous solid particles used as a cocatalyst are particles of an oxide selected from the group consisting of silica alumina, aluminosilica, magnesium oxide titanium oxide, iron oxide, zirconium oxide …
