Vacuum Pyrolysis
Vacuum or vacuum moving bed pyrolysis includes a combination of slow and fast pyrolysis conditions. Course solids are heated relatively slowly to temperatures higher than those of slow pyrolysis, while the gas is removed from the hot temperature zone relatively quickly by applying a reduced pressure of less than 0.20 atm in the process. Vacuum pyrolysis is not a rapid heating technique and is in the same thermal regime of time and temperature as slow pyrolysis (charcoal production); however, yields of liquid that are over 50% of the original biomass are achieved by removing the vapors as soon as they are formed by operating under a partial vacuum—essentially the converse of work at high pressures, in which the liquids are held in the charring mass to increase the yield of char.
