Abstract: Novel sorbent systems for the desulfurization of cracked-gasoline and diesel fuels are provided which are comprised of a bimetallic promotor on a particulate support such as that formed of zinc oxide and an inorganic or organic carrier. Such bimetallic promotors are formed of at least two metals of the group consisting of nickel, cobalt, iron, manganese, copper, zinc, molybdenum, tungsten, silver, tin, antimony and vanadium with the valence of same being reduced, preferably to zero. Processes for the production of such sorbents are provided wherein the sorbent is prepared from impregnated particulate supports or admixed to the support composite prior to particulation, drying, and calcination. Further disclosed is the use of such novel sorbents in the desulfurization of cracked-gasoline and diesel fuels whereby there is achieved not only removal of sulfur but also an increase in the olefin retention in the desulfurized product.

Abstract: A sorbent composition is provided which can be used in the desulfurization of a hydrocarbon-containing fluid such as cracked gasoline or diesel fuel. The sorbent composition contains a support component and a promoter component with the promoter component being present as a skin on the support component. Such sorbent composition is prepared by a process of impregnating a support component with a promoter component, wherein the promoter component has been melted under a melting condition, followed by drying, calcining, and reducing to thereby provide the sorbent composition.

Abstract: The present invention provides a process for producing a polymer having a desired melt index. Pursuant to the process of the present invention an inorganic oxide sample is obtained and dried to a desired extent by controlling the drying conditions. The dried inorganic oxide sample is treated with an organoaluminoxide and a metallocene to form a metallocene catalyst system and contacted with an olefin under conditions supporting polymerization to form a polyolefin sample. The drying conditions are selected to produce an inorganic oxide sample capable of generating a metallocene catalyst system which produces polymer having the desired melt index.
