The rapid pyrolysis of lignocellulosic products, especially forest waste, is conducted in a fluidized bed of hot refractory particles. The pyrolysis products, comprising solid carbonaceous residue (i.e., char), tars and gas, escape from the bed and cross an overheating zone comprising a packed bed contactor supplied by a rainfall of hot refractory particles. The carbonaceous solid residue is then separated from the produced gases, a portion of which is recycled to fluidize the bed, and burned in a conveyed bed combustion reactor, thus heating the refractory particles that supply the packed bed contactor and the fluidized bed. |
