Methods of forming densified biomass

Patent · 16 August 2022

OSTI ID:1924984

Tumuluru, Jaya Shankar

A method includes densifying a biomass feedstock having a moisture content of at least about 30% by weight and drying the biomass feedstock to form a densified biomass having a moisture content of less than about 10% by weight. Some methods include comminuting a biomass feedstock, pressing the biomass feedstock to form a plurality of pellets, heating the plurality of pellets to remove water therefrom, and cooling the plurality of dried pellets. The plurality of pellets exhibits a moisture content of at least about 20% by weight after pressing. The plurality of dried pellets exhibits a moisture content of less than about 10% by weight. A system for forming densified biomass may include a preheater, a press, and a dryer.
