  • Patent number: 10308878
    Abstract: Disclosed herein is an economically viable co-process for converting biomass to liquid biohydrocarbon fuels and for upgrading heavy deteriorate petrol-oils to high value transportation fuels. In the process, cellulose, hemi-cellulose and lignin, which are composed of ligno-cellulosic biomass, are converted to the bio-hydrocarbons (alkanes and aromatics) that are currently derived almost exclusively from fossil fuels. The resulted hydrocarbon liquid can be separated against their boiling points for gasoline, diesel and heavy oils. The heavy oils can then cracked into lower molecular weight hydrocarbons. Meanwhile, the co-processed heavy petro-fuels are partially converted into lower molecular weight hydrocarbons that fall in the boiling point range of gasoline and diesel.

  • Patent number: 10023809
    Abstract: This disclosure provides a new approach for bio-oil upgrading using methane as reductant instead of hydrogen. Guaiacol, produced by thermal degradation of lignin, represents a model compound for upgrading of fast pyrolysis bio-oils by deoxygenation. To overcome the high cost of H2, methane is used to deoxygenate guaiacol. On Pt/C catalyst, in terms of guaiacol conversion and product distribution, methane is found to exhibit comparable deoxygenation performance as H2. Its lifetime, however, is lower (<3 hrs). In one embodiment, the lifetime of Pt—Bi/C catalyst is extended by addition of bismuth as a promoter.

  • Patent number: 9169179
    Abstract: Hydrothermal digestion of cellulosic biomass solids in a glycerol solvent system can convert both the cellulosic biomass solids and the glycerol into a glycol reaction product for subsequent processing without the need for further solvent separation. Methods for digesting cellulosic biomass solids in a glycerol solvent system can comprise: providing cellulosic biomass solids and a slurry catalyst in a hydrothermal digestion unit, the slurry catalyst being capable of activating molecular hydrogen; heating the cellulosic biomass solids in the hydrothermal digestion unit in the presence of the slurry catalyst, molecular hydrogen, and a solvent system comprising glycerol, thereby forming soluble carbohydrates; and at least partially converting the soluble carbohydrates and the glycerol into a reaction product comprising a glycol within the hydrothermal digestion unit.

  • Patent number: 9039790
    Abstract: Methods for making a fuel composition comprising contacting one or more components of a hydroprocessing feedstock, for example both a fatty acid- or triglyceride-containing component and a paraffin-rich component, with hydrogen under catalytic hydroprocessing conditions are disclosed. The methods are effective to upgrade the component(s) and provide a hydroprocessed biofuel. A representative method utilizes a single-stage process in which hydrogen-containing recycle gas is circulated through both a hydrodeoxygenation zone and a hydrocracking zone in series.

  • Patent number: 9037298
    Abstract: The present invention provides novel techniques for controlling the output of a distillation sub-process by controlling, using model predictive control, the temperature of steam used in the distillation sub-process, wherein the steam is generated in a milling and cooking sub-process. In particular, the present techniques are presented in the context of biofuel production, wherein the temperature of a cook tube generated in a milling and cooking sub-process may be controlled to optimize the energy utilization in the ethanol/water separation of a side stripper column, which uses the cook flash steam as an energy source. However, the present techniques may also be applied to other suitable applications, such as liquor processing, where steam generated in a different process may be used in a distillation process to help separate water from the liquor.

  • Patent number: 9028697
    Abstract: The moisture absorption capacity of biofuels can be more or less 10 times that of fossil diesel oil, causing biofuels to form acids that induce metal corrosion and form deposits in the fuel tank and pipe lines. Methods for removing moisture from stored biofuels and plant oils are described wherein glycerol is used as a solvent to extract the moisture from the bioliquid or oil, comprising the steps of placing the biofuel or oil in fluid contact with glycerol, incubating for a time, and then removing the glycerol. A cellulous ester dialysis or other semi-permeable membrane may be used to prevent the glycerol from contaminating the biofuel while allowing moisture to pass. Crude glycerol produced as a byproduct of biodiesel production may be used in the method of the disclosed invention with good result. Preferred embodiments of apparatus that employ the method of the subject invention are described.

    Abstract: A system is described that includes a pyrolyzer and a primary condenser. The primary condenser is coupled to the pyrolyzer and configured to receive pyrolytic vapors from the pyrolyzer. The primary condenser is further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with a condensing liquid, to form a bio-oil component mixture having multiple separated phases. At least a portion of the condensing liquid includes a component that is extracted as a separated stable phase from a second bio-oil component mixture resulting from a prior pyrolysis cycle.
