Apparatuses and methods for controlling heat for rapid thermal processing

摘要

Disclosed is a method for controlling heat for rapid thermal processing of carbonaceous biomass material or wood to produce charcoal. The method for processing a moisture-containing carbonaceous feedstock comprises contacting the moisture-containing carbonaceous feedstock with heated air to form a reduced-moisture carbonaceous feedstock. The reduced-moisture carbonaceous feedstock is pyrolyzed to form char; and combusting the char and transferring a portion of the combustion heat to an air stream to form the heated air.
