1. A method for the preparation of a zeolite having MFI framework comprising:
forming a homogeneous aqueous mixture of water soluble oxidized disulfide oil (ODSO), a silica source, an aluminum source, an alkali metal source, and a structure directing agent;
heating the homogeneous aqueous mixture under conditions and for a time effective to form a crystalline zeolite as precipitate suspended in a supernatant as an intermediate suspension;
recovering the precipitate from the intermediate suspension; and
calcining the recovered precipitate is calcined at a suitable temperature, temperature ramp rate and for a suitable period of time at to realize porous MFI framework zeolite.
