Pyrolysis is the heating of biomass at a temperature of 650-800 k and at a pressure of 05 01- mpa in the absence of air to convert biomass into , liquid oils and gaseous solid charcoal compounds. Pyrolysis of biomass is a particularly attractive process if all three products - gas, wood tars, and charcoal - can be used gasification of biomass with air is perhaps the most flexible and best-developed process for conversion of biomass to fuel today, yielding a low energy gas that can be burned in existing gas/oil boilers or in engines.
