Abstract: A method for torrefaction of biomass using a torrefaction reactor vessel having stacked trays including: feeding the biomass to an upper inlet of the vessel such that the biomass material is deposited on an upper tray of a vertical stack of trays in the reactor; cascading the biomass down through the trays by passing the biomass through an opening in each of the trays to deposit the biomass on a lower tray; as the biomass moves around each of the stacked trays, heating the biomass material with an oxygen deprived gas; extracting moisture containing gas having passed through the biomass on the upper trays wherein the extraction is immediately below each of the upper trays; as the biomass undergoes torrefaction in the lower trays of the stacked trays, retaining the gas with the biomass until the biomass falls from the stacked trays to a pile of biomass in the reactor vessel; exhausting gases containing organic compounds volatized by the torrefaction of the biomass through a gas outlet on the vessel at an elevation between the stacked trays and the pile of biomass, and discharging torrefied biomass from a lower outlet of the torrefaction reactor vessel.

Abstract: Method and system for the production of solids from raw materials. These materials are subjected to a continuous torrefaction treatment at a temperature of between 200 and 320°C. Heating takes place by means of circulating gases that entor into direct heat exchange with the raw materials fed to the torrefaction chamber. The ga.es liberated during torrefaction are combusted while feeding in oxygen and discharged after the beat has been extracted from the flue gas thus produced. The heat from the flue gas is used to heat the gaseous medium that is fed to the torrefaction chamber. The production of effluent is prevented in that the condensate formed in the process is combusteal, optionally after specific purification steps.
