TorreCat Technology - Benefits

ATS TorreCat™ Technology uses an oxidation catalyst to combust off-gas from a torrefaction reactor and thereby produce low-temperature, low-residual-oxygen combustion flue gases. These low-temperature, low-residual-oxygen combustion flue gases can then be used directly in the torrefaction process, coming into contact with the biomass in both the reactor and the cooler. The direct use of all torrefaction gases and combustion flue gases results in the highest level of heat integration and energy efficiency. In addition, the ability to use the combustion flue gases directly in the cooler eliminates the need for cooling water or, in the alternative, the need to purchase inert gas for cooling.
