WET BIOMASS TREATMENT

A process for the treatment of biomass with a relatively high water and salt content such as agricultural or forestry residues comprises: (a) mechanically pre-treating wet biomass; (b) extracting the pre-treated biomass with water at a temperature between 40 and 160oC at a pressure which keeps water...

Beschreibung
Zusammenfassung:	A process for the treatment of biomass with a relatively high water and salt content such as agricultural or forestry residues comprises: (a) mechanically pre-treating wet biomass; (b) extracting the pre-treated biomass with water at a temperature between 40 and 160oC at a pressure which keeps water substantially liquid; (c) dewatering the heated biomass to produce a dewatered biomass and an aqueous effluent; (d) optionally heating the dewatered biomass at a temperature above 160oC; (e) drying, before or after step (d), and compacting the heat-treated biomass. The treated biomass can be used as a solid fuel. The aqueous effluent is subjected to anaerobic treatment, to produce biogas an/or alcohols.
