TORREFACTION SYSTEMS AND METHODS INCLUDING CATALYTIC OXIDATION AND/OR REUSE OF COMBUSTION GASES DIRECTLY IN A TORREFACTION REACTOR, COOLER, AND/OR DRYER/PREHEATER

摘要

A method for torrefying biomass comprises using an oxidation catalyst to combust gas produced by torrefaction, and thereby produce combustion flue gas. The method also comprises introducing the combustion flue gas into a torrefaction reactor and/or a cooler.
