  • Publication number: 20140288338
    Abstract: The present invention relates to the field of biomass derived fuels. It further relates to thermochemical production of liquids (biooils) from biomass. Specifically the present invention relates to methods of upgrading biooil. More specifically it relates to a method for upgrading biooil comprising contacting a dispersed mixture of hydrocarbon liquids, biooil, and partially upgraded biooil, with a transition metal containing catalyst and hydrogen gas at a temperature of around 330° C. and a pressure of about 1700 psi (11.7 MPa) for a period of time sufficient to reduce the oxygen content of the biooil such that it separates on cooling into an aqueous phase and an organic phase, and optionally, to further subject the organic phase to hydrotreating, hydrocracking or catalytic cracking to produce a mixture of hydrocarbons boiling in the range of gasoline, diesel and jet fuel.

  • Publication number: 20140256999
    Abstract: Algae oil feeds comprise a wide range of molecular species forming a complex mixture of molecules having varying sizes and therefore varying boiling points, comprise high nitrogen, oxygen, and fatty acid content, but comprise low sulfur, saturated hydrocarbons, and triglycerides. The wide range of molecular species in the algae oil feeds, very unusual compared to conventional refinery feedstocks and vegetable oils, may be upgraded into fuels by conventional refining approaches such as thermal and/or catalytic-hydroprocessing. Hydrotreating at high pressure over large-pore catalyst, and optionally followed by FCC cracking, has shown a beneficial product slate including coke yield. Thermal treatment prior to hydrotreating may improve hydrotreating feedstock quality.

    Abstract: A process for upgrading residuum hydrocarbons is disclosed. The process may include: contacting a residuum hydrocarbon fraction and hydrogen with a first hydroconversion catalyst in a first ebullated bed hydroconversion reactor system; recovering a first effluent from the first ebullated bed hydroconversion reactor system; solvent deasphalting a vacuum residuum fraction to produce a deasphalted oil fraction and an asphalt fraction; contacting the deasphalted oil fraction and hydrogen with a second hydroconversion catalyst in a second hydroconversion reactor system; recovering a second effluent from the second hydroconversion reactor system; and fractionating the first effluent from the first ebullated bed hydroconversion reactor system and the second effluent from the second hydroconversion reactor system to recover one or more hydrocarbon fractions and the vacuum residuum fraction in a common fractionation system.

  • Publication number: 20140221711
    Abstract: A system and process to make cyclic, saturated hydrocarbons from aromatic hydrocarbon intermediates from catalyzed nonoxidative dehydroaromatization (DHA) of methane. The system includes two reaction zones, one containing a dehydroaromatization catalyst and a second containing a hydrogenation catalyst. Methane reacts in the first reaction zone with the DHA catalyst resulting in aromatic hydrocarbons concomitantly produced with hydrogen gas. The hydrogen gas is removed and introduced to the second reaction zone with the aromatic hydrocarbon to reductively produce saturated, cyclic hydrocarbons.

  • Patent number: 8766028
    Abstract: The invention disclosed relates to a process for refining a hydrocarbon feed to make substantially styrene-free C6-C8 aromatic hydrocarbons (BTX). The hydrocarbon feed, for example, unhydrotreated pyrolysis gasoline, is distilled to make a BTX rich stream containing styrene which is fractionated to separate C6 and C7 hydrocarbons from C8 hydrocarbons including styrene. Styrene in the C8 hydrocarbons reacts in the presence of a selective etherification catalyst with a C1-C3 lower alkyl alcohol to form the corresponding styrene ether, which is then separated by distillation into a styrene ether stream and a C8 hydrocarbons rich stream. The C8 hydrocarbons rich stream is then re-mixed with the C6 and C7 hydrocarbons, and sent to hydrogenation reactors to remove sulphur and olefinic hydrocarbons to form substantially styrene-free BTX.
