Abstract
A method of forming a biomass feedstock comprises comminuting biomass into biomass fragments, densifying the biomass fragments into biomass pellets, thermally treating the biomass pellets to form thermally treated biomass pellets, and reducing a particle size of the thermally treated biomass pellets to form biomass particles. The biomass particles exhibit substantially the same properties throughout a volume of the biomass particles. Also disclosed are biomass particles and a biomass processing system.

A method of forming a biomass feedstock, comprising:
- comminuting biomass into biomass fragments;
- densifying the biomass fragments into biomass pellets;
- thermally treating the biomass pellets to form thermally treated biomass pellets;
- and
- reducing a particle size of the thermally treated biomass pellets to form biomass particles, the biomass particles exhibiting substantially the same properties throughout a volume of the biomass particles.
Biomass particles comprising:
- non-fossil biological material exhibiting one or more of a linear dimension of from about 100 microns to about 300 microns and a density greater than or equal to about 500 kg/m3, an interior portion of the biomass particles exhibiting substantially the same one or more properties as an exterior portion of the biomass particles.
A biomass processing system comprising:
- a comminution apparatus configured to comminute biomass;
- a densification apparatus configured to densify the comminuted biomass;
- a thermal treatment apparatus configured to thermally degrade the densified comminuted biomass;
- and
- a size reduction apparatus configured to reduce a particle size of the thermally degraded densified biomass to a linear dimension of from about 100 microns to about 300 microns.
