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.
