Apparatus for mixing reactive fluids which are capable of ignition or explosion, at elevated temperature and pressure, for subsequent conversion by contact with a catalyst, such as a (partial) oxidation catalyst or in a combustion zone, comprising in sequence an upstream inlet end, a mixer, an expander, a diffuser and a downstream outlet end, the outlet end being characterised by a greater available cross-sectional area than any of the inlet end, mixer and expander, and the expander having substantially increasing internal cross-sectional area in downstream direction, wherein the available cross-sectional area of the expander at any point along its length is less than the difference in internal cross-section of the expander at its downstream and its upstream ends, a process therefor and the use thereof, in particular the use thereof in a process for the catalytic partial oxidation of hydrocarbon feedstock. |
