Abstract: 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.

Abstract: In a system for adjusting the position of a first member relative to a second, support member regarded as fixed, the support member comprises a base having an upright at each of its two ends. The first member is inside the two uprights of the support member and the uprights are substantially parallel to the axis of the first member. The position adjustment system is locked in a chosen position by a clamping device, whose component parts are mounted on a clamping rod passing through the two uprights and whose axis is the clamping axis, which is substantially perpendicular to the axis of the first member.
