ABSTRACT
Pyrolysis has become of major interest due to the flexibility in operation, versatility of the technology, and adaptability to a wide variety of feedstocks and products. Pyrolysis operates in anaerobic conditions where heat is usually provided externally and the constituents of biomass are thermally cracked to gases and vapors, which usually undergo secondary reactions, thereby giving a broad spectrum of products. There are a number of conditions and circumstances which have a major impact on the products and the process performance. These include feedstock, technology, reaction temperature, additives, catalysts, hot-vapor residence time, solid residence time, and pressure.
