  • Publication number: 20120000792
    Abstract: This invention relates to a process for electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams selectively to mercaptan compounds that can then be more easily removed from the electrochemically treated product stream by either caustic extraction or thermal decomposition of the thiol functionality to hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means in the substantial absence of hydrogen and in the substantial absence of water.

  • Patent number: 7985332
    Abstract: The electrodesulfurization of heavy oil feedstreams is accomplished wherein a heavy oil feedstreams, along with hydrogen, is passed the cathode side of an electrochemical cell wherein the organically bound sulfur compounds in the heavy oil are reduced and the sulfur is released as hydrogen sulfide. The hydrogen sulfide can be fed directly into the anode side of the electrochemical cell to produce sulfur and hydrogen or it can be passed to an oxidation zone containing an aqueous solution of an oxidized metal salt.

  • Publication number: 20110147274
    Abstract: After desulfurizing a hydrocarbon feedstream using an alkali metal reagent, the hydrocarbon feedstream can include particles of spent alkali metal salts. The spent alkali metal salts can be separated from the hydrocarbon feedstream and regenerated to form an alkali metal reagent, such as a alkali hydroxide or alkali sulfide. The regeneration process can pass through an intermediate stage of forming an alkali carbonate by successive reactions with carbon dioxide and calcium oxide. The calcium oxide can also be regenerated.

  • Publication number: 20100320120
    Abstract: Heat from nuclear reactor as a source of thermal energy is applied to the conversion of carbonaceous materials such as heavy petroleum crude oils, coals and biomass to liquid hydrocarbons. The heat is applied to provide at least a portion of the process heat used in the high temperature, short contact time hydropyrolysis of the carbonaceous material which is supplied with hydrogen generated by a high temperature process such as high temperature steam electrolysis, the sulfur-iodine cycle, the hybrid sulfur cycle, the zinc-zinc oxide cycle, a solid oxide fuel cell or by methane steam cracking. The heat from the nuclear reactor may be used to generate electricity to operate high temperature steam electrolysis used in generation of the hydrogen. By the use of nuclear thermal energy, hydrocarbon resource utilization for process heat is eliminated along with carbon dioxide evolution associated with burning of the hydrocarbon resource to generate process heat.
