As most of you know, we are commercializing a unique form of torrefaction technology, developed by NC State University (NCSU). This process will densify, add value to, improve the characteristics of woody biomass, making it a much better feedstock for which to co-fire with coal, make superior pellets and briquettes and to use in gasifier operations. It also allows treated biomass to be shipped more economically and for greater distances.

Torrefaction for entrained-flow gasification of biomass

A major technical obstacle in entrained-flow gasification of biomass concerns the size reduction and the subsequent pneumatic transport of the biomass powder. The fibrous structure of fresh biomass makes it very difficult and costly to reduce its particle size down to below 500 microns.
