Torrefaction and Syntesis Gas Production

V.V. Kosov, V.F. Kosov, V.A. Sinelshchikov & V.M. Zaichenko
The products of torrefaction are bio­char as the main product and condensable and non­condensable volatiles as a by­product. Non­condensable volatiles mainly consist of carbon dioxide and carbon monoxide while the main liquid torrefaction products are acetic acid and water with smaller quantities of methanol, formic acid, lactic acid, and furfural. High­temperature conversion of the volatiles into synthesis gas is a way to increase the overall efficiency of torrefaction and a green solution for torrefaction technology....
