Bio-Oil: An Introduction to Fast Pyrolysis and its Applications

Murray, T.,  F. Resende, and G. Luo. 2014.  WSU Fact Sheet FS140E. The United States has targeted biofuels generated from domestic biomass supplies as a significant contributor for future liquid fuel supplies. Reliance on domestic fuel production opens the door for a wide range of opportunities for natural resource managers, farmers, and other landowners who will be instrumental in developing the industry, its technologies, and its utilization of agricultural crop residues and forestry biomass. This publication discusses bio-oil produced via fast pyrolysis, its applications, and associated biomass feedstocks.
