  • Publication number: 20140250770
    Abstract: A unique process and catalyst is described that operates efficiently for the direct production of a high cetane diesel type fuel or diesel type blending stock from stoichiometric mixtures of hydrogen and carbon monoxide. This invention allows for, but is not limited to, the economical and efficient production high quality diesel type fuels from small or distributed fuel production plants that have an annual production capacity of less than 10,000 barrels of product per day, by eliminating traditional wax upgrading processes. This catalytic process is ideal for distributed diesel fuel production plants such as gas to liquids production and other applications that require optimized economics based on supporting distributed feedstock resources.

  • Publication number: 20130220881
    Abstract: Exemplary embodiments of the invention provide a process of increasing the cetane number rating of a diesel oil feedstock. The process involves reacting a diesel fuel feedstock in liquid form with ozone in gaseous form in the presence of an alcohol having two or more carbon atoms and at least one polar solvent different from the alcohol, thereby forming an ozonated diesel oil containing oxidized byproducts, wherein the alcohol and said polar solvent are employed in amounts totaling no more than about 10 vol. % of the feedstock. The oxidized byproducts are then separated from the ozontated diesel oil to produce a hydrocarbon product of increased cetane number rating relative to the feedstock oil. The product can be used as a diesel fuel or as a diesel fuel extender mixed with conventional diesel fuel of low cetane number.

  • Publication number: 20130056391
    Abstract: A process for selective removal of mercaptan from aviation turbine fuel feed includes mixing aviation turbine fuel feed with hydrogen, at a pressure in a range from 3 bar to 20 bar to obtain a reaction mixture. The reaction mixture is heated at a temperature range of 150° C. to 350° C. to obtain a heated mixture. The heated mixture is reacted with a hydrotreating catalyst in a rector to obtain a reactor effluent, and H2S gas is stripped from the reactor effluent to obtain a stripper bottom product. Moisture is removed from the stripper bottom product to obtain aviation turbine fuel product having less than 10 ppm mercaptan. The aviation fuel product has improved properties such as color and acidity. Embodiments also relate to an aviation turbine fuel product having less than 10 ppm mercaptan prepared by the described process of the present invention.

  • Patent number: 8366910
    Abstract: A process is described for hydroconversion of a mixture of organic oils of different origins in a conventional hydrotreatment unit, constituted by at least two catalyst beds, under moderately severe process conditions to obtain diesel fuel oil. The process includes injection of a stream of oil of animal or plant origin, with independently adjusted flow rates, from the second catalyst bed of the hydrotreatment unit onwards, in accordance with the variations in temperature observed in each of the catalyst beds after the first bed. The process is applicable to conventional hydrotreatment units, and makes it possible to overcome the effects of the highly exothermic nature of hydroconversion reactions in oils of animal and/or plant origin in hydrotreatment process for obtaining specified diesel fuel oil.
