  • Patent number: 6673239
    Abstract: A system and process for removing water and heteroatom-containing compounds from hydrocarbons and for regenerating the adsorbent used in the system and process is disclosed and includes contacting the hydrocarbon stream with a water adsorbent and a heteroatom-containing compound adsorbent. The regeneration includes passing an isoparaffin over the water-adsorbent, then passing the isoparaffin over the heteroatom-containing compound adsorbent; and, optionally; cooling the effluent; separating such into a hydrocarbon phase and a water phase in a settler; removing a portion of the hydrocarbon phase for mixing with water; returning the hydrocarbon/water mixture to the settler; removing some of the hydrocarbon phase from the settler to form a recycle isoparaffin stream for use as a portion of the stripping stream; and removal of a portion of the water phase from the settler to form a waste water stream containing water and heteroatom-containing compound.

  • Patent number: 6635795
    Abstract: While contacting under regeneration conditions an oxygen-containing stream with a sorbent comprising a promoter metal and zinc sulfide which has been sulfurized by contact with sulfur-containing hydrocarbons such as cracked-gasolines and diesel fuel, the oxygen partial pressure is controlled in a range of 0.5 to 2.0 psig to minimize sulfation of the sorbent.

  • Publication number: 20030192811
    Abstract: A hydrocarbon desulfurization system employing regenerable solid sorbent particulates in a fluidized bed desulfurization reactor. The sulfur-loaded sorbent particulates are continuously withdrawn from the reactor and transferred to a regenerator. A novel solids transport mechanism provides for the safe and effective transfer of the sulfur-loaded sorbent particulates from the high pressure hydrocarbon environment of the reactor to the low pressure oxygen environment of the regenerator.

  • Publication number: 20030188993
    Abstract: In a desulfurization process for the removal of organosulfur compounds from a hydrocarbon fluid stream such as cracked-gasoline or diesel fuel wherein a bifunctional sorbent system is employed, surface treatment of the bifunctional sorbent during the use of same for desulfurization results in an extension of the useful life of the bifunctional sorbent prior to the regeneration and reactivation of same for further use in the desulfiurization of the hydrocarbon fluid stream.
