    Abstract: A system for effecting the reconditioning of catalyst particles used in the reforming of a hydrocarbon stream which provides a vertically elongated confined chamber that will have the particles flow down between screens of perforated plates in a descending column through a carbon burn-off section and a halogenation section. A preferred design provides for an annularform column of particles with gas flows being out-to-in laterally through the column and, in addition, incorporates a drying section in the lower portion of the chamber. An overall system with a preferred design also combines means for scrubbing the flue gas stream from the burn-off section and returning it to the chamber and, in addition, combines means for continuously recycling a steam-halogen-air stream through the halogenation section.

    Abstract: Alumina is dry-mixed with an oxide of an iron group metal and an oxide of a Group VIB metal, or compounds convertible thereto upon subsequent calcination, and the blend is discharged into contact with a peptizing agent on a pelletizing disc to form spheroidal pellets. Upon calcination in an oxidizing atmosphere, the composite is particularly useful as a hydrotreating catalyst for the conversion and separation of nitrogenous and sulfurous compounds contained in petroleum fractions.
