Abstract: A method is disclosed for producing a mechanically stable, energy dense and water-resistant biomass product. By utilizing a unique two-step heating process in combination with mechanical compression, the resulting biomass product retains its physical shape and strength after immersion in ambient water for many hours. The treatment is effective for a variety of cellulosic biomass materials including forest slash wood.

Abstract: Disclosed herein is a binder-free product and process for making the product. The product is a mechanically stable, water resistant torrefied biomass product that does not comprise an extrinsic binder additive. The product is made using a combination of appropriate pre-treatment steps and compressing the conditioned biomass feedstock into a thermally managed compaction device comprising at least one modified die. The modified die allows for differential cooling/heating modifications so as to control the temperature near the entrance to the compaction device and passing the formed torrefied biomass into a post-formation curing zone.
