Title: Chapter 29 - Pyrolysis of Lignocellulosic Biomass: Oil, Char, and Gas

Book ·

Biomass pyrolysis is a technology that uses high temperatures to break down biomaterials like wood without completely burning them. Products include char, combustible gas, and vapors; the vapors can be condensed into a liquid with myriad uses. This chapter serves as a primer for the fundamental physics and chemistry involved in biomass pyrolysis, common reactor systems, and some reported uses for the products.
