Abstract: An improved vortex-type mixing device for a down-flow hydroprocessing reactor is described. The device provides improved overall mixing efficiency of an existing mixing volume in the mixing of gas and liquid phases in two-phase systems while reducing the pressure drop through the device, as compared with prior art devices. Typical hydroprocessing applications include hydrotreating, hydrofinishing, hydrocracking and hydrodewaxing.

Abstract: An improved nozzle device for a down-flow hydroprocessing reactor is disclosed. The down-flow nozzle is useful in the petroleum and chemical processing industries in catalytic reactions of hydrocarbon feedstocks in the presence of hydrogen, at an elevated temperature and pressure, to provide for the mixing and distribution of gas and liquid to reactor catalyst beds. Typical hydroprocessing applications include hydrotreating, hydrofinishing, hydrocracking and hydrodewaxing.
