  • Patent number: 10851314
    Abstract: Disulfide oil (DSO) compounds recovered as a by-product of the mercaptan oxidation of a hydrocarbon refinery feedstock and their oxidized derivatives, oxidized disulfide oils (ODSO) are effective as a diluent to lower the viscosity and thereby improve the pipeline transportation properties of heavy oils, and particularly of wellhead crude oil. The use of the DSO and/or ODSO compounds as diluents converts an otherwise extremely low value or waste oil product into a valuable commodity that has utility in improving the transportation properties of heavy oils, particularly in oil field pipeline applications.

  • Patent number: 8993818
    Abstract: Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars/sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A self-sustainable process was designed to reduce the coke by co-feeding sugars/sugar derivatives with the paraffin products from hydrogenation of sugars/sugar derivatives. Paraffins without complete conversion result in products with less aromatics and relatively low density compared with the products directly from zeolite upgrading. Thus, the process is more economically favorable.

    Abstract: A process for hydrogenating olefins is disclosed. The olefins are present in a feed gas which includes H2 and one or more sulfur compounds. The sulfur compounds may include H2S and organic sulfur compounds. The feed gas is passed through a reactor at an inlet temperature from 100° C. to 250° C. The reactor contains a catalyst which is active at the inlet temperature. The reactor may be adiabatic. Saturated hydrocarbons are formed from the olefins. A temperature gradient may be formed in the reactor due to the exothermic nature of the hydrogenation reaction, causing the temperature to increase downstream in the reactor. At temperatures higher than the inlet temperature, H2S may be formed from organic sulfur compounds. A gas mixture including saturated hydrocarbons, H2S and H2 exits the reactor and may be brought into contact with a chemical adsorbent which removes the H2S. The gas stream may then be passed to a steam methane reformer.

    Abstract: A process continuously hydrogenating unsaturated compounds, in which particles of a first hydrogenation catalyst are suspended in a liquid phase in which an unsaturated compound is dissolved, the liquid phase, in the presence of a hydrogenous gas at a first partial hydrogen pressure and at a first temperature, is conducted through a packed bubble column reactor in cocurrent counter to the direction of gravity, the effluent from the bubble column reactor is sent to a gas-liquid separation, the liquid phase is sent to a crossfiltration to obtain a retentate and a filtrate, the retentate is recycled into the bubble column reactor and the filtrate, in the presence of a hydrogenous gas at a second partial hydrogen pressure and at a second temperature, is passed over a bed of a second hydrogenation catalyst, the second partial hydrogen pressure is at least 10 bar higher than the first partial hydrogen pressure.

  • Publication number: 20130245344
    Abstract: Poly alpha olefins (PAOs) are characterized by very low viscosity and excellent Noack volatility. A preferred process for synthesizing said PAOs involves first oligomerizing low molecular weight linear alpha olefins in the presence of a single site catalyst at high temperatures without adding hydrogen and then subsequently oligomerizing at least a portion of the product from the first step in the presence of an oligomerization catalyst.

  • Patent number: 8518351
    Abstract: An apparatus is disclosed for hydrocracking hydrocarbon feed in a hydrocracking unit and hydrotreating a diesel product from the hydrocracking unit in a hydrotreating unit. The hydrocracking unit and the hydrotreating unit shares the same recycle gas compressor. A warm separator separates recycle gas and hydrocarbons from diesel in the hydrotreating effluent, so fraction of the diesel is relatively simple. The warm separator also keeps the diesel product separate from the more sulfurous diesel in the hydrocracking effluent, and still retains heat needed for fractionation of lighter components from the low sulfur diesel product.

  • Patent number: 8519207
    Abstract: The present invention relates to a process for the hydrogenation, in particular selective hydrogenation of at least one unsaturated hydrocarbon compound comprising reacting the at least one unsaturated hydrocarbon compound with hydrogen in the presence of a hydrogenation catalyst, wherein the hydrogenation catalyst comprises a mixture of an ordered intermetallic compound and an inert material. According to another aspect, the present invention is concerned with the use of a mixture of at least one ordered intermetallic compound and at least one inert material, as a catalyst. The mixtures for use as a catalyst in the present invention can be prepared easily and achieve a superior activity in relation to the prior art, while preserving the high selectivity to the target compounds, e.g. in the selective hydrogenation of acetylene to ethylene.

  • Publication number: 20130195727
    Abstract: A fluidized bed biogasifier is provided for gasifying biosolids. The biogasifier includes a reactor vessel and a feeder for feeding biosolids into the reactor vessel at a desired feed rate during steady-state operation of the biogasifier. A fluidized bed in the base of the reactor vessel has a cross-sectional area that is proportional to at least the fuel feed rate such that the superficial velocity of gas is in the range of 0.1 m/s (0.33 ft/s) to 3 m/s (9.84 ft/s). In a method for gasifying biosolids, biosolids are fed into a fluidized bed reactor. Oxidant gases are applied to the fluidized bed reactor to produce a superficial velocity of producer gas in the range of 0.1 m/s (0.33 ft/s) to 3 m/s (9.84 ft/s). The biosolids are heated inside the fluidized bed reactor to a temperature range between 900° F. (482.2° C.) and 1700° F. (926.7° C.) in an oxygen-starved environment having a sub-stoichiometric oxygen level, whereby the biosolids are gasified.
