Catalytic Roles of Nano-Sized Oxides Composed with Zeolite for Hydrocracking, Catalytic Cracking and Reforming

Nano-sized oxides, especially alumina hold catalytic roles by composed with zeolite for resid catalytic cracking, low pressure deep desulfurization, isoparaffin production through hydrocracking, and naphtha reforming to isoparaffins. Selective co-production of propylene and aromatics from the heavier n-paraffins also occurs on the nano-structured catalysts consisting of MFI-type zeolite.
