Lignocellulosic Biofuels Commercialization: Lignocellulosic biomass is considered a promising feedstock for biofuels production due to its wide availability, and low cost. Most importantly, it does not affect the food chain or competes with plants for human food and animal feed. However, the conversion process has not been economical. The usual biochemical route used requires pretreatment, enzymatic hydrolysis, fermentation, and distillation to transform this lignocellulosic biomass into biofuel, thereby reducing its economic advantages. One promising path for conversion is pyrolysis of the biomass into bio-oil using bio-reactors and its subsequent refinement into transportation fuels using catalytic reactors. This study identifies the temperature, gas flow rate, and catalyst that optimize the yield and quality of the bio-oil produced from the catalytic pyrolysis of biomasses, such as switchgrass. Dedicated perennial energy crops such as switchgrass, crop residues, and forestry biomass are primary lignocellulosic biomass that could potentially displace 30% of the United States current petroleum consumption if used as biofuels [1].
