Fast Pyrolysis and Bio-oil Production from Agricultural Residues and Energy Crops

Fast pyrolysis is rapid heating in the absence of oxygen resulting in decomposition of organic material. When applied to biomass, fast pyrolysis produces liquids (bio-oil), char and gas. Bio-oil is a complex mixture of hundreds of oxygenated organic compounds resulting from the decomposition of the cellulose, hemicellulose, and lignin of which the biomass is composed. Raw bio-oil has energy contents about half of that of diesel fuel and can be burned in boilers or turbines. It can also be further upgraded into transportation fuels. The Agricultural Research Service (ARS) of the USDA is studying the fast pyrolysis of potential perennial energy crops and animal wastes for bio-oil production. For forage biomass materials, effects of variables such as maturity at harvest and genotype have been studied both analytically and in a bench scale pyrolysis reactor. Process parameters for the reactor including material and energy balances will be presented. Furthermore, the chemical compositions and fuel properties of the bio-oil produced from different forage plants and poultry wastes will be compared and contrasted.
