Pyrolysis based approaches are proving to be the cheapest and most efficient method to convert solid biomass into renewable fuels and chemicals.  Zeolite catalyst can be added directly into the pyrolysis reactor to produce aromatics and olefins directly from solid biomass.  The advantage of this approach is that high value aromatics and olefins can be produced directly from solid biomass in a single catalytic reactor using inexpensive zeolite based catalysts.  In a specially designed fluidized bed reactor the pyrolysis vapors enter into the zeolite pores where they undergo a series of dehydration, decarbonylation and oligomerization reactions to produce aromatics and olefins.  The shape, pore structure, and active sites of the zeolite catalysts are critical in obtaining high yields of the desired aromatic products. As will be demonstrated in this presentation chemistry, chemical catalysis, chemistry and chemical engineering are critical 21st century needs to help make renewable energy a reality.
