Abstract
A process for making a catalytic system for converting solid biomass into fuel of specialty chemical products is disclosed. The process includes preparing a slurry precursor mixture by mixing an aluminosilicate clay material with a pore regulating agent and optionally a binder, shaping the mixture into shaped bodies; removing the pore regulating agent to form porous shaped bodies, preparing an aqueous reaction mixture comprising the porous shaped bodies in presence of a zeolite seeding material, and thermally treating the aqueous reaction mixture to form the catalyst system. The catalyst system can comprise, for example, a MFI-type zeolite.
