593489 Disclosed is a method for the production of pellets or briquettes from a lignin containing material, comprising the steps of: passing the lignin containing material having a moisture content less than about 30% by weight into a reactor; heating the lignin containing material to 180-235°C by injecting steam into the reactor; maintaining the material in the reactor for 1-12 minutes to release lignin; reducing the pressure in the reactor; and forming the treated material to form pellets or briquettes. Also disclosed are the lignin containing pellets of briquettes produced by the process.
