Abrégé

A process for cleaning and beneficiating biomass is described which may allow removal of entrained salts and light volatiles from biomass materials. The process may also minimize energy use through capturing steam and flue gases for re-use. The process may generally comprise the following steps: prewashing and/or preheating a biomass, pressurizing the biomass in a steam explosion vessel, rapidly depressurizing the steam explosion vessel, releasing the steam from the steam explosion vessel entrained with fine lignin-enriched particles into a cyclone-type gas expansion vessel, routing the steam from the gas expansion vessel to the input hopper, subjecting the biomass to a second washing step, mechanically removing a portion of the water from the biomass, and evaporatively heating the biomass.

Classes IPC  ?

• C10L 5/44 - Combustibles solides à base essentielle de matières d'origine non minérale de matières végétales
• B01J 3/04 - Récipients sous pression, p. ex. autoclaves
• C10L 9/08 - Traitement des combustibles solides en vue d'améliorer leur combustion par traitement thermique, p. ex. calcination
• C10L 5/36 - Forme

After the biomass has been steam-exploded, it may be washed and used as an engineered soil.
