Method for gasifying biomass

Gasification method comprising the following steps of: a) bringing, in a main reactor, beads made of steel, an alloy, glass or ceramic, at a temperature between 600° C. and 1,000° C., into contact with a feedstock mixture comprising water and a biomass, the biomass comprising an organic part and sal...

Zusammenfassung:Gasification method comprising the following steps of: a) bringing, in a main reactor, beads made of steel, an alloy, glass or ceramic, at a temperature between 600° C. and 1,000° C., into contact with a feedstock mixture comprising water and a biomass, the biomass comprising an organic part and salts, the main reactor being pressurised to more than 224 bar and at a temperature above 200° C. b) gasifying the organic part in the presence of the beads, thereby forming a gaseous phase, an aqueous phase and a solid residue, and whereby the salts precipitate on the beads, forming a salt shell covering the beads, c) separating the beads from the organic part, d) regenerating the beads.
