24623-60 ABSTRACT The invention relates to a vessel for the generation of synthesis gas at a high pressure, using hydrocarbons, particularly natural gas, nahptha and/or refinery gas in a catalytic endothermic reform- ing section with a plurality of reformer tubes heated externally and filled with a catalyst, a mixture of hydrocarbons and steam en- tering the reformer tubes positioned by a common plate. The reform- ing gas generated in said tubes flows from the tubed section into the partial oxidation section which has a larger diameter than the tubed section and the shape of a pressure vessel closed at one end, the free ends of the reformer tubes penetrating into said section, and in which additional hydrocarbons and oxygen or oxygen-rich gas are mixed with the reforming gas. The aim is to design a vessel suitable for the required thermal reactions, to provide reliable operation of the vessel and to ensure complete reactions. This aim is achieved by installing a plurality of inlet devices for hydro- carbons and/or oxygen or oxygen-rich gas in the cylindrical shell of the partial oxidation section, the centre-lines of said devices being parallel to or inclined towards the radial streams, which form a plane, and said devices being spaced at a certain distance from the outlet end of the reformer tubes such that a rotary gas vortex is produced and that the product gas stream flows through the outer section of the chamber, heats the reformer tubes and leaves the reforming section via the outlet nozzle.
