  • Patent number: 10654781
    Abstract: This invention provides a method for catalytic conversion of carbohydrates to low-carbon diols using alloy catalysts. In the process, carbohydrates as the feedstock are subjected to one-step catalytic conversion to realize the highly efficient and selective production of ethylene glycol etc. under hydrothermal conditions, with an alloy catalyst composed of tin, and a transition metal such as iron, cobalt, nickel, rhodium, ruthenium, palladium, iridium, platinum and copper, or a mixture thereof. The reaction is carried out in water at a temperature range of 120-300° C., with a hydrogen pressure range of 1-13 MPa. Compared with the present petroleum based synthesis technology of ethylene glycol, the method in this invention possesses advantages of using renewable feedstock, high atom economy and environmental friendly.

  • Patent number: 9302966
    Abstract: A process for converting polyhydric alcohols to monoalcohols in a counter current column reactor with a metal based catalyst supported on a porous membrane coated over a tubular system that delivers hydrogen where a hydrocarbon (low polarity) liquid solvent is fed at the bottom of the column reactor and an aqueous liquid having polyhydric alcohols therein is fed into the top of the reactor such that the aqueous liquid flows countercurrent to the low polarity solvent liquid and further wherein the low polarity solvent liquid is less dense than the aqueous liquid such that the two liquids are subject to phase separation. Monoalcohols are formed by hydrogenolysis reactions of polyhydric alcohols on the metal catalyst. Monoalcohols phase separate from the aqueous phase to the hydrocarbon solvent. Monoalcohols are further separated from the organic solvent.

In another aspect, the linker can include phosphotungstic acid (PTA) or other similar solid acid agents. In another aspect, the support can be selected from alumina, carbon, silica, a zeolite, TiO2, ZrO2, or another suitable material. A specific example of a support includes zeolite, such as a NaY zeolite. The Ru nanoparticle can have a size range from about 1 nm to about 25 nm, and can be obtained by reduction of Ru salts.

  • Patent number: 8227648
    Abstract: Systems and processes for dehydration of a process stream in the production of motor fuel grade ethanol (MFGE) can include temperature controlled adsorption of water in the process stream, and heat pumping to transfer heat from the process stream to a heat sink using one or more stages of heat pumping. One stage of heat pumping can be achieved during the regeneration process of a temperature controlled adsorber by desorbing the adsorbed water at a thermal condition enabling useful heat recovery. Another stage of heat pumping can be achieved during the adsorption process of a temperature controlled adsorber by transferring the heat of water adsorption to a heat sink. The heat sink with respect to each stage of heat pumping can be a solids separation unit, such as a beer column.

  • Patent number: 8212087
    Abstract: Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy or sugary materials, to produce ethanol and/or butanol, e.g., by fermentation.

  • Patent number: 8143460
    Abstract: A method comprising applying a controlled flow cavitation apparatus to an alcohol production process in order to increase alcohol yield. A grain-based liquid medium comprising grain and a liquid carrier can be passed through a controlled flow cavitation apparatus at a velocity capable of generating a hydrodynamic cavitation zone where the grain size can be reduced. One or more controlled flow cavitation apparatuses can be applied at various points of an alcohol production process, such as a starch-to-ethanol production process.

    Abstract: A process for converting a sugar, sugar alcohol, or glycerol to a valuable chemical is described. The process may use a support comprising zirconium oxide promoted by a polyacid or promoter material. A catalytically active metal may be impregnated on the polyacid-promoted zirconium oxide support and the catalyst may then be introduced the sugar, sugar alcohol, or glycerol a source of hydrogen under reaction conditions. At least 40 wt % of the sugar, sugar alcohol or glycerol may be converted to a polyol and/or a shorter carbon-chain alcohol that may include at least one of propylene glycol, ethylene glycol, glycerin, methanol, ethanol, propanol and butandiols. Specific processes for converting glycerin having a selectivity for propylene glycol and for converting sorbitol with a selectivity for propylene glycol, ethylene glycol, and/or glycerin are also described.

  • Patent number: 8067646
    Abstract: Systems and processes for dehydration of a process stream in the production of motor fuel grade ethanol (MFGE) can include temperature controlled adsorption of water in the process stream, and heat pumping of the associated heat of adsorption. The process can include providing a process stream (110) including ethanol and water to a first temperature controlled adsorber (102) where water is removed by adsorption to produce an MFGE product stream (114) and an associated heat of adsorption. A cooling fluid can be provided to the first temperature controlled adsorber (102) to remove heat of adsorption and produce a heated cooling fluid (120). Heat from the heated cooling fluid can be provided to a heat sink.
