Described is a mixing device for mixing a gaseous stream of a fuel and an oxidant that has a cylindrical mixing chamber, means for injecting a gaseous stream of the fuel tangentially along the inner surface of the wall of the mixing chamber, and means for injecting a stream of the oxidant axially along the central longitudinal axis of the mixing chamber, wherein the diameter of the mixing chamber and the dimensions and location of the means for injecting the fuel and the oxidant are such that the tangentially injected stream of the fuel forms a wall jet around the axially injected stream of the oxidant without impinging upon the other stream. A reactor for the partial oxidation of a hydrocarbonaceous fuel containing the mixing device and to a process for the catalytic partial oxidation of a hydrocarbonaceous fuel using the mixing device is further described.
A mixing device for mixing a first gaseous stream comprising a fuel and a second gaseous stream comprising an oxidant, which mixing device comprises:
A reactor for the partial oxidation of a fuel comprising a mixing device and a partial oxidation reaction zone, wherein the mixing device comprises a cylindrical mixing chamber having a wall and a central longitudinal axis, a first injector for injecting a first gaseous stream comprising fuel tangentially along an inner surface of the wall, and a second injector for axially injecting a second stream comprising oxidant along the central longitudinal axis, wherein the diameter, and dimensions and locations of the injectors are such that, during normal operation, the injected first stream forms a wall jet around the injected second stream without impinging upon the injected second stream.
A process for the catalytic partial oxidation of a fuel, which process comprises mixing a first gaseous stream comprising the fuel and a second gaseous stream comprising oxidant to obtain a feed mixture, and contacting the feed mixture with a catalyst, wherein the first stream and the second stream are mixed in a mixing device comprising a cylindrical mixing chamber having a wall and a central longitudinal axis, a first injector for injecting the first stream tangentially along an inner surface of the wall, and a second injector for injecting the second stream axially along the central longitudinal axis, wherein the diameter of the mixing chamber, and the dimensions and location of the first injector and the second injector are such that, during normal operation, the injected first stream forms a wall jet around the injected second stream without impinging upon the injected second stream.
