  • Patent number: 10066179
    Abstract: Methods and systems for forming densified lignocellulose biomass are described. Methods can include torrefaction and densification of a lignocellulose feedstock. Temperature and pressure control and lubricant addition throughout the process can provide for the lignin to dissipate more completely throughout the biomass and better coat the cellulose. The product can include a high level of lignin and low volatiles, both of which can improve the energy density of the product. In addition, the process can include a cooling step that can increase the crystallinity of the solidified lignin, which can further increase bulk density and improve grindability of the product.
