  • Publication number: 20170137727
    Abstract: A treated oil, such as a treated heavy oil, which has a viscosity which is lower than the viscosity of the oil prior to the treatment thereof (i.e., the initial oil). The temperature at which 80 mass % of the treated oil has boiled is within 25° C. of temperature at which 80 mass % of the oil prior to the treatment thereof has boiled. Thus, the treated oil and the oil prior to the treatment thereof, have distillation curves or boiling point curves which are the same as or approximate to each other.

  • Publication number: 20170072388
    Abstract: A catalyst for the carbonylation of dimethyl ether to methyl acetate. The catalyst comprises a zeolite, such as a mordenite zeolite, at least one Group IB metal, such as copper, and/or at least one Group VIII metal, such as iron, and at least one Group IIB metal, such as zinc. Such a catalyst with combined metals provides enhanced catalytic activity, improved stability, and improved selectivity to methyl acetate, and does not require a halogen promoter, as compared to a metal-free or copper only zeolite.

  • Patent number: 8871081
    Abstract: A process for treating a heavy oil which comprises subjecting a heavy oil to cavitation to reduce the viscosity of the heavy oil. The treated heavy oil, which has a reduced viscosity and specific gravity, thus is more pumpable and transportable, which facilitates further processing. The treated heavy oil also can be fractionated with less severity than untreated heavy oil.

  • Patent number: 8834834
    Abstract: Processes for producing synthesis gas from biomass in which char particles, which are formed during the production of synthesis gas from biomass, are employed as catalysts. The char particles may be used as catalysts in a gasifier or in a thermal reformer, whereby gaseous components, formed as a result of the gasification of the biomass, such as methane, light alkyl and aromatic compounds, and phenolics, as well as tar, may be reformed and/or converted into synthesis gas.

  • Publication number: 20140158940
    Abstract: A method of producing a synthetic gas or a synthesis gas from a biosolid, such as dewatered sludge, that has a solids content that does not exceed 30 wt. %. The biomass having a solids content that does not exceed 30 wt. % is mixed with tar-rich materials and/or char particles, and optionally a bulking agent. The tar-rich materials and/or char particles may be a by-product of producing synthesis gas from a biomass such as refuse-derived fuels. The resulting mixture then is heated to provide a mixture having a solids content of at least 75 wt. %. The mixture having a solids content of at least 75 wt. % then is gasified under conditions to produce a synthetic gas rich in CO/CO2 or a synthesis gas rich in H2/CO.

  • Publication number: 20140094622
    Abstract: A method of producing methyl acetate from methanol in which methanol and carbon monoxide are reacted in a first reaction zone to provide a reaction product including methyl acetate, acetic acid, and unreacted methanol. The reaction product then is passed to a second reaction zone, wherein the acetic acid is reacted with the unreacted methanol to provide additional methyl acetate. The method is a more efficient method for producing methyl acetate from methanol in that acetic acid is not separated from the reaction product.

  • Patent number: 8636923
    Abstract: A process for producing synthesis gas, or syngas, from biomass. The process comprises contacting biomass with oxygen, or oxygen and steam, in an amount effective to oxidize the biomass and to heat the biomass to a temperature to no greater than 750° C. At least one combustible material also is contacted with oxygen and steam to heat the at least one combustible material to a temperature of at least 1,100° C., to provide a hot gas derived from the oxidized combustible material. The latter maybe residual products derived from the process itself as char, tar, or hydrocarbons. The oxidized biomass then is contacted with the hot flue gas to heat the biomass to a temperature of at least 900° C., thereby producing synthesis gas. The synthesis gas then is recovered. Such process provides a method of providing heat for producing synthesis gas without consuming a portion of the synthesis gas to provide such heat, thereby providing an increased yield of synthesis gas.

  • Publication number: 20130217925
    Abstract: A process for converting methanol to ethanol which comprises reacting methanol and carbon monoxide in the presence of a catalyst to produce a product comprising at least 25 mole % methyl acetate and, in some instances, acetic acid. The acetic acid then is reacted with at least one alcohol to produce at least one acetate selected from methyl acetate, ethyl acetate, and butyl acetate. The at least one acetate (if produced) and the methyl acetate produced as a result of reacting methanol and carbon monoxide then are hydrogenated to produce ethanol. Syngas may be produced from biomass to produce all or a portion of the methanol, hydrogen, and carbon monoxide requirements for the process.
