    摘要: A system and process for producing xylene and other alkylated aromatics includes one or more fluidized bed reaction zones that provide contact between the reactants (i.e., an aromatic reactant and an alkylating reagent). Improved conversion and selectivity is realized when the alkylating reagent is stagewise injected into the fluidized bed at one or more locations downstream from the location of aromatic reactant introduction into the fluidized bed. Preferably, the alkylating reagent is introduced at a plurality of locations along the axial direction of the fluidized bed reaction zone, or at plural locations between a plurality of different fluidized bed reaction zones.

    摘要: A process for upgrading low octane naphthas to produce gasoline products with low levels of benzene and aromatics while retaining a high pool octane uses a paraffinic naphtha reformer feed which is dehexanized to provide a C.sub.7 + fraction which is fed to the reformer and a C.sub.6 fraction which is fed together with the C.sub.6 fraction from the reformer effluent to a catalytic upgrading step where the low octane components from the naphtha and the benzene from the reformate are converted to a low benzene, high octane gasoline by alkylation of the benzene and other aromatics present in the reformate. The process has the advantage that benzene make in the reformer is reduced by the partial by-passing of the C.sub.6 benzene precursors around the reformer; in addition, improved benzene alkylation results from the presence of additional light olefins generated by the cracking of paraffins from the paraffinic naphtha. the reaction is preferably carried out in a turbulent fluidized bed reaction zone.

    摘要: An olefin hydration catalyst is regenerated with a non-oxidizing light gas, such as hydrogen. Light olefins, especially propylene, are converted to a mixture of alcohol(s), such as isopropanol (IPA) and ether(s), such as diisopropylether (DIPE) by contacting a feed containing the olefin with water and/or alcohol with the olefin hydration catalyst. Regeneration conditions include temperatures of from about 150.degree. C. to about 550.degree. C., pressures below about 1000 psig (6900 kPa). Lower pressures of regeneration unexpectedly demonstrated more effective catalyst regeneration through greater coke removal.

    摘要: A hydrodesulfurization process for catalytically hydrosulfurizing highly aromatic feeds, especially catalytically cracked feeds such as light cycle oils from catalytic cracking processes and aromatic extracts, employs a hydrodesulfurization catalyst containing zeolite beta. The zeolite beta based catalyst is more effective for effecting desulfurization than comparable amorphous catalysts or catalysts based on other large pore size zeolite and is capable of achieving a high degree of desulfurization at relatively low levels of conversion. The hydrodesulfurization catalyst comprises a transition metal hydrogenation component, preferably Co/Mo, on zeolite beta together with an inert matrix. The zeolite beta based catalyst may be mixed with amorphous catalyst such as Co/Mo/alumina. The low sulfur products are useful as blending components for road diesel fuels and other distillate fuels.

    摘要: A process is disclosed for improving the Viscosity Index of a hydrocarbon lubricating oil comprising the steps of providing a flow reactor having separate first and second inlet ports for the separate co-injection of lubricating oil and an organic peroxide, charging said lubricating oil and said organic peroxide of said flow reactor through said first and second inlet ports respectively, controlling the relative flowrates of said lubricating oil and organic peroxide reactants together with the total volumetric flowrate through said flow reactor to maintain a flow regime which favors diffusional mixing between said organic peroxide and said lubricating oil, and maintaining said organic peroxide and said lubricating oil under conversion conditions including temperatures of between about 50.degree. and 300.degree. C. and pressure sufficient to maintain said lubricating oil and said organic peroxide substantially in the liquid phase. Controlling the flow regime to favor diffusional rather than convective mixing between the lubricating oil and the organic peroxide has surprisingly been found to markedly enhance Viscosity Index improvement.
