Method for gasifying biomass comprising the following steps of: a) bringing, in a main reactor , beads heated to a temperature between 600°C and 1,000°C, and preferably between 900°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 beads being made of a material that is selected from steel, a metal alloy, glass or a ceramic, and preferably having a diameter of between 500 μm and 2 mm, in step a), the main reactor being pressurised to more than 222 bar, for example to more than 250 bar, and preferably heated to a temperature above 200°C and below 374°C, for example to a temperature between 200°C and 300°C, b) at least partially gasifying the organic matter, in the presence of the beads at a temperature above 374°C and at a pressure above 222 bar, preferably at a temperature between 400°C and 500°C and at a pressure above 250 bar, 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 , the method further comprising the following steps of: c) separating the beads covered by the salt shell from the organic part, d) regenerating the beads , for example, by the following sub-steps: d1) removing the salt shell of the beads , for example by washing the beads with an aqueous solution at a temperature below 374°C, whereby the salts are dissolved, d2) heating the beads to a temperature between 600°C and 1,000°C and preferably between 900°C and 1,000°C, step d2) preferably being carried out by combustion in the presence of dioxygen. a) bringing, in a main reactor , beads heated to a temperature between 600°C and 1,000°C, and preferably between 900°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 beads being made of a material that is selected from steel, a metal alloy, glass or a ceramic, and preferably having a diameter of between 500 μm and 2 mm, in step a), the main reactor being pressurised to more than 222 bar, for example to more than 250 bar, and preferably heated to a temperature above 200°C and below 374°C, for example to a temperature between 200°C and 300°C, the beads being made of a material that is selected from steel, a metal alloy, glass or a ceramic, and preferably having a diameter of between 500 μm and 2 mm, in step a), the main reactor being pressurised to more than 222 bar, for example to more than 250 bar, and preferably heated to a temperature above 200°C and below 374°C, for example to a temperature between 200°C and 300°C, b) at least partially gasifying the organic matter, in the presence of the beads at a temperature above 374°C and at a pressure above 222 bar, preferably at a temperature between 400°C and 500°C and at a pressure above 250 bar, 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 covered by the salt shell from the organic part, d) regenerating the beads , for example, by the following sub-steps: d1) removing the salt shell of the beads , for example by washing the beads with an aqueous solution at a temperature below 374°C, whereby the salts are dissolved, d2) heating the beads to a temperature between 600°C and 1,000°C and preferably between 900°C and 1,000°C, step d2) preferably being carried out by combustion in the presence of dioxygen. d1) removing the salt shell of the beads , for example by washing the beads with an aqueous solution at a temperature below 374°C, whereby the salts are dissolved, d2) heating the beads to a temperature between 600°C and 1,000°C and preferably between 900°C and 1,000°C, step d2) preferably being carried out by combustion in the presence of dioxygen. <EOS>
