  • Patent number: 10526544
    Abstract: A process for converting a biomass-derived pyrolysis oil in which the pyrolysis oil is contacted with hydrogen in the presence of a certain catalyst containing one or more Group VIII metals is provided. The catalyst is prepared by (a) comulling (1) a refractory oxide, (2) a small amount of liquid, chosen such that the Loss On Ignition (LOI) at 485° C. of the mixture is from equal to or more than 20 wt % to equal to or less than 70 wt % based on the total weight of the catalyst composition, and (3) at least one or more metal component(s), which is/are at least partially insoluble in the amount of liquid used, to form a mixture, and the metal component(s) is/are one or more Group VIII metal component, (b) optionally shaping, and drying of the mixture thus obtained; and (c) calcining the composition thus obtained to provide a calcined catalyst.

  • Patent number: 8507738
    Abstract: A co-processing combining a first selective catalytic bed consisting of only one metal element selected from group VIB metals and of at least one conventional hydrotreating bimetallic catalytic bed. The co-processing provides control of the hydroconversion reactions of the triglycerides and/or fatty acids of biomass oil diluted in a refinery stream of petroleum hydrocarbons and minimizes the generation of gaseous products that are undesirable to the process, while maintaining the levels of unsaturated hydrocarbons hydrogenation and of heteroatomic contaminants removal from the refinery stream of petroleum hydrocarbons. The co-processing selectively providing n-paraffins of even number of carbon atoms, generated from the biomass oil, which are incorporated in a hydrotreated liquid product in petroleum refining HDT units.

  • Patent number: 8193399
    Abstract: A process has been developed for producing diesel fuel from renewable feedstocks such as plant oils and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a diesel fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture.

  • Publication number: 20110203253
    Abstract: A method for preparing a fuel composition is described, and includes the step of preparing a bio-derived fuel component that contains a mixture of iso-saturated alkanes and normal-saturated alkanes. The method further includes the step of determining if the ratio of iso-saturated alkanes to normal-saturated alkanes is at least about 2.0. If that requirement is met, the bio-derived fuel component is usually combined with a petroleum-derived component, resulting in the fuel composition. Related compositions are also described, in which the weight ratio of iso-saturated alkanes to normal-saturated alkanes is at least about 2.0; and the composition has a freeze point less than about ?50° C.

  • Patent number: 7928273
    Abstract: Processes for producing hydrocarbons in the gasoline and jet fuel range. The processes involve the thermal decarboxylation of fatty acids, which can be derived from the hydrolysis of triglycerides, which triglycerides can be vegetable oils, animal fats, or combinations thereof. The resulting hydrocarbons can be hydrocracked, and, optionally, isomerized and/or hydrotreated, to yield hydrocarbons in the jet fuel or gasoline range. Where the resulting hydrocarbons include olefinic double bonds, they can alternatively be combined with low molecular weight olefins, and subjected to olefin metathesis to yield hydrocarbons in the jet fuel or gasoline range.
