    Abstract: Fuel gas streams containing oxygen are treated by a process that performs simultaneous sweetening and absorption of mercaptan compounds. The mercaptan oxidation catalyst and an aqueous alkaline solution and a low vapor pressure liquid hydrocarbon stream contact the fuel gas feed in a mixing vessel to sweeten the mercaptans and absorb resulting disulfides from the gas stream into the liquid hydrocarbon stream. A separation vessel receives the dual phase effluent from the mixing vessel and settles the effluent into three component phases. An upper gas phase provides a treated fuel gas stream, an intermediate hydrocarbon phase provides liquid hydrocarbons containing disulfides for removal from the process, and recycle to the mixing vessel and an alkaline solution drains from the bottom of the settler. The aqueous alkaline solution is pumped back to the mixing vessel in combination with the mercaptan oxidation catalyst.

    Abstract: A process is disclosed for treating hydrocarbon streams by the catalyzed oxidation of mercaptans to disulfides. In the process, the hydrocarbon-containing stream is admixed with air and then passed through an oxidation zone. The oxidation zone effluent is decanted to remove an aqueous alkaline solution in a high pressure separation zone. It is then depressurized into a low pressure separator in which dissolved excess nitrogen and oxygen are substantially removed from the hydrocarbons. The treated hydrocarbons are then pressurized to force their flow into a low pressure product receiving facility. This sequence eliminates or minimizes the discharge of gaseous nitrogen and oxygen and hydrocarbon vapors in the storage facility, where they are pollution abatement problems and possible safety hazards.

    Abstract: A process is disclosed for treating hydrocarbon streams for the purpose of removing mercaptans and also converting the remaining mercaptans to disulfides which remain in the hydrocarbon stream being treated. The hydrocarbons rise through a contacting column countercurrently to a descending stream of an aqueous alkaline solution. A limited amount of an oxygen-containing gas is passed into an intermediate point in the column thereby dividing it into an upper sweetening section and a lower extraction section. The flow rate of the oxygen-containing stream is preferably low enough that any gas not consumed in the catalytic oxidation of mercaptans becomes dissolved in the hydrocarbon product stream, and preferably remains dissolved at atmospheric pressure.

    Abstract: A catalytic composite comprising a metal chelate mercaptan oxidation catalyst and a quaternary ammonium hydroxide impregnated on a solid adsorptive support is disclosed. The quaternary ammonium hydroxide is represented by the structural formula ##STR1## wherein R is a hydrocarbon radical containing up to about 20 carbon atoms and selected from the group consisting of alkyl, cycloalkyl, aryl, alkaryl and aralkyl, R.sub.1 is a substantially straight-chain alkyl radical containing from about 5 to about 20 carbon atoms, and R.sub.2 is selected from the group consisting of aryl, alkaryl, and aralkyl. The catalytic composite is particularly adapted to the oxidation of mercaptans contained in a sour petroleum distillate.
