In recent years, a good deal of attention has been focused on the thermal conversion of biomass to gases and liquids, and in particular, on the products obtainable from short time, high temperature pyrolysis of wood and other lignocellulosics. This flash pyrolysis is usually carried out at or near atmospheric pressures, while hydropyrolysis commonly employs hydrogen pressures to 20 MPa. Residence times of only a few seconds or less with reaction at high temperatures requires a reactor configuration capable of very high heating rates. Two of the most appropriate designs are the entrained flow reactor, and the fluidized bed reactor. Many flash pyrolysis studies have employed one or the other of these reactor types. In general, two approaches to flash pyrolysis of biomass have been used by various workers. One approach has the objective of producing a maximum yield of a desirable gas, which in atmospheric pressure non-catalytic pyrolysis processes is usually ethylene, or other olefins.
