ABLATIVE FAST PYROLYSIS

Ablative pyrolysis, in which much larger particle sizes can be employed than in other systems, as the heat is transferred from a hot surface to the biomass particle and the process, is limited by the rate of heat supply to the reactor rather than the rate of heat absorption by the pyrolyzing biomass. Ablative pyrolysis is fundamentally different from fluid bed processes from the mode of heat transfer through a molten layer at the hot reactor surface, use of large particles, and absence of a fluidizing gas.
