Abstract: A catalytic reforming process for the operation of a magnetically stabilized fluidized bed. The process utilizes catalyst compositions characterized as a particulate material which can be oriented within, and formed into a magnetically stabilized fluidized bed which comprises: (i) particles of average size ranging from about 10 micrometers (.mu.m) to about 4000 .mu.m, each containing a nonferromagnetic component and a catalytically active component composited with a single elongate ferromagnetic component or plurality of parallelly aligned elongate ferromagnetic components. The ferromagnetic component, or components, are multidomain, having dimensions of at least 1 .mu.m in all directions and a length:diameter (L/D) ratio of at least 2 but not more than 17.3, and the ferromagnetic component, or components, is present in the composite particles as inclusions within a nonferromagnetic matrix constituting at least 0.5%, preferably at least 5%, but not more than 3/2(L/D).sup.

Abstract: A process for selectively removing nitrogen from petroleum distillate feedstocks, notably lube oil distillates or lube base stocks without significant desulfurization of said petroleum distillate feedstocks, especially lube oil distillates or lube base stocks, while hydrotreating the oil to improve odor, color, improve stability, and the like. In accordance therewith, a supported, non (metal-promoted) carbon-containing molybdenum sulfide HDN/HDS selective hydrotreating catalyst is formed from a precursor composite made by compositing a preselected quantity of a porous, refractory inorganic oxide with a complex salt characterized by the formula B.sub.x [MoO.sub.y S.sub.4-y ] where B is (a) an alkyl substituted diammonium ion, or (2) an alkyl substituted ammonium ion or quaternary ammonium ion; x is 1 where B is an alkyl substituted diammonium ion, or 2 where B is an alkyl substituted ammonium or quaternary ammonium ion; and y is 0, or a fraction or whole number ranging up to 3.

Abstract: A novel catalyst composition, and process for the preparation of magnetic, catalytic composites to improve catalytic metals utilization. A particulate magnetic alloy of iron or cobalt is contacted with a phosphate ion containing solution and reacted therewith sufficiently to form a surface film thereupon, removed from said solution, preferably dried, then admixed or otherwise incorporated within an inorganic oxide matrix, notably alumina, as inclusions, the composite particle is then contacted with a solution which contains a compound, or compounds, of a Group VIII noble metal, notably platinum, which is deposited within the composite particle in catalytically effective amounts without significant loss of the catalytic metal due to surface deposition of the catalytic metal upon said particulate magnetic alloy inclusions.
