Abstract: A spray ring, for wetting char and/or slag in a water bath with a wetting fluid. The spray ring comprises a loop conduit arranged in a loop-line. The loop conduit is at an inlet point provided with an inlet for feeding the wetting fluid into the loop conduit in an inlet flow direction. The loop-line has a plurality of outlet openings for spraying the wetting fluid out of the loop conduit. The inlet flow direction has a component that is tangential to a loop-line flow direction of the wetting fluid through the loop conduit at the inlet point.

Abstract: Synthesis gas is produced from a carbonaceous fuel, using a process in a gasification reactor. The carbonaceous fuel and an oxygen containing stream are supplied to a burner of a gasification reactor, wherein a CO2-containing transport gas is used to transport the solid carbonaceous fuel to the burner. The weight ratio of CO2 to the carbonaceous fuel is less than 0.5 on a dry basis. The carbonaceous fuel is partially oxidized in the gasification reactor, whereby a gaseous stream of synthesis gas is obtained. This synthesis gas can be further processed in a downstream process path to convert it into a hydrocarbon product. The downstream process path may contain a methanol-synthesis reactor to produce the hydrocarbon product in the form of methanol. The downstream process path may contain a Fischer-Tropsch synthesis reactor to produce one or more from a range of hydrocarbon products.
