  • Patent number: 8628656
    Abstract: Processes for the desulfurization of a cracked naphtha by the reaction of hydrogen with the organic sulfur compounds present in the feed are disclosed. In particular, processes disclosed herein may use one or more catalytic distillation steps followed by further hydrodesulfurization of the naphtha in a fixed bed reactor. It has been found that the formation of recombinant mercaptans in the fixed bed reactor effluent may be reduced or eliminated by reducing the concentration of hydrogen sulfide and/or olefins at the exit of the fixed bed reactor. The reduction or elimination in the formation of recombinant mercaptans may be accomplished by recycling a select portion of the fixed bed reactor effluent to the fixed bed reactor, where the select portion has a relatively low or nil concentration of olefins. Processes disclosed herein may thus facilitate the production of hydrodesulfurized cracked naphthas having a total sulfur content of less than 10 ppm, by weight.

  • Publication number: 20120018350
    Abstract: The desulfurization of fossil fuels is provided by the combination of fossil fuels with an aqueous mixture of ozone or hydrogen peroxide and a Tetraoctylphosphonium salt phase transfer catalyst, and the mixture is then subjected to reactive mixing to form oxidize sulfur compounds in the fuel. The polar oxidized sulfones species are removed via another mixing step. The desulfurization device can be in the form of a portable device which provides for continuous mixing-assisted desulfurization for the removal of sulfur containing compounds from fossil fuels such as diesel fuel.

  • Patent number: 8097149
    Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.

  • Publication number: 20110220552
    Abstract: A method removes corrosive sulfur compounds from transformer oil. By adding a mixture of rare earths containing aluminum oxide and aluminum silicate to the transformer oil, and enriching the same with an aqueous solution of soluble metal salts, the corrosive sulfur compounds in the transformer oil are neutralized with defined heating and cooling phases. Advantageously, no additional chemical components, such as passivators, are added to the transformer oil. When using a tank for receiving the mixture of the rare earths containing aluminum oxide and aluminum silicate, the reaction can run in the tank. Any aging products that may be present, and the bonded corrosive sulfur compounds are effectively retained within the tank by a filter system, and can be disposed of with the tank.
