    摘要： Mercaptans and olefins are removed from paraffin-rich feed streams through the use of dual zone catalytic distillation in the substantial absence of hydrogen. The mercaptans are reacted with the olefins using a first catalyst such as a sulphonated resin to form less volatile thioethers removed as part of a net bottoms stream. The remaining olefins are oligomerized in a higher catalyst zone preferably employing a catalyst, such as a dealuminated Y zeolite, having a higher oligomerization activity at the imposed conditions.

    摘要： The present invention relates to a continuous in-situ process for the removal of organically bound sulfur existing as mercaptans, sulfides and thiophenes comprising the steps of (a) contacting a heavy oil with aqueous sodium hydroxide at a temperature of about 380.degree. C. to about 450.degree. C. for a time sufficient to form sodium sulfide, and (b) steam stripping the sodium sulfide of step (a) at a temperature sufficient to convert said sodium sulfide to sodium hydroxide and recirculating the sodium hydroxide from step (b) back to step (a) and removing hydrogen sulfide and the metals from the organically bound metal complex of the sodium sulfide to convert it back to sodium hydroxide, in which case the sulfur may be recovered as H.sub.2 S rather than the metal sulfide. Optionally, molecular hydrogen may be added in the first step. The present invention is useful in removing organically bound sulfur that has been recognized to be difficult to remove, such as thiophenes. Beneficially, the process also removes other heteroatoms (nitrogen and oxygen) and metals (vanadium, iron, nickel) and reduces asphaltene content (n-heptane insolubles), micro concarbon residue, coke, 975.degree. F. fractions, TGA fixed carbon, average molecular weight, density and viscosity.

    摘要： Sulfur-bearing liquid hydrocarbon feedstocks such as kerosene undergo desulfurization and deodorization by contacting such feedstocks with sodium hydride at normal atmospheric pressure and at elevated temperatures. The resulting liquid is further contacted with a mineral acid such as sulfuric acid and an alkaline neutralizing agent such as caustic soda. The liquid may also be contacted with an oxidizying agent such as sodium hyprochlorite prior to being contacted with the neutralizing agent and with a dehydrating agent such as soda ash after being contacted with the neutralizing agent.

    摘要： A technique for continuous conversion of diene-containing aliphatic hydrocarbon feedstock to heavier hydrocarbon products wherein the feedstock is contacted at elevated temperature under endothermic high severity reaction conditions with a fluidized bed of acidic zeolite fine catalyst particles, comprising methods and means for:maintaining the fluidized catalyst bed in a vertical reactor having a turbulent reaction zone by passing vapor upwardly through the reaction zone at a velocity greater than dense bed transition velocity to a turbulent regime and less than transport velocity for the average catalyst particle;feeding a continuous stream of feedstock into the reaction zone, said feedstream comprising sufficient C.sub.3.sup.+ alkanes to require net endothermic reaction conditions;withdrawing a portion of coked catalyst from the reaction zone, oxidatively regenerating the withdrawn catalyst, heating the catalyst substantially above process temperature in the fluidized bed reactor, and returning hot regenerated catalyst to the reaction zone at a rate to control catalyst activity and reaction temperature under conditions of reaction severity to effect feedstock conversion to an aromatics-rich hydrocarbon effluent stream; andseparating an aromatics-rich product from the fluidized bed effluent stream.Aromatics yield is increased by recovering a recycle stream comprising C.sub.5.sup.+ aliphatic hydrocarbons from the fluidized bed effluent stream for further conversion in the fluidized bed to increase aromatics product yield.
