  • Patent number: 8425633
    Abstract: Methods, process, apparatus, equipment, and systems are disclosed for converting biomass into bio-oil fractions for chemicals, materials, feedstocks and fuels using a low-cost, integrated fast pyrolysis system. The system improves upon prior art by creating stable, bio-oil fractions which have unique properties that make them individually superior to conventional bio-oil. The invention enables water and low-molecular weight compounds to be separated into a final value-added fraction suitable for upgrading or extracting into value-added chemicals, fuels and water. Initial bio-oil fractions from the process are chemically distinct, have low-water content and acidity which reduces processing costs normally associated with conventional bio-oil post-production upgrading since fewer separation steps, milder processing conditions and lower auxiliary inputs are required. Biochar is stabilized so that it can be handled safely.

    Abstract: Algae-derived synthetic coal and filtrates. The invention described herein provides an algae-derived synthetic coal product and filtrates and process for preparing the same using an improved hydrothermal carbonization process. The synthetic coal product is similar to natural bituminous coal in terms of percent carbon content and energy equivalency while at the same time containing relatively low levels of sulfur and contaminant heavy metals. Unlike natural coal and other fossil fuels, because the carbon of the biomass is formed through photosynthesis, carbon dioxide formed during combustion is a “carbon neutral” event with little or no “new” carbon dioxide being added to the earth's atmosphere. The algae-derived filtrates contain useful constituents.

  • Patent number: 8409303
    Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.

    Abstract: Methods are provided for producing low oxygen biomass-derived pyrolysis oil from carbonaceous biomass feedstock. The carbonaceous biomass feedstock is pyrolyzed in the presence of a steam reforming catalyst to produce char and pyrolysis gases. During pyrolysis, a portion of the oxygenated hydrocarbons in the pyrolysis gases is converted into hydrocarbons by steam reforming also yielding carbon oxides and hydrogen gas. The hydrogen gas at least partially deoxygenates a residual portion of the oxygenated hydrocarbons. Additional hydrogen gas may also be produced by water-gas shift reactions to deoxygenate the residual portion of the oxygenated hydrocarbons in the pyrolysis gases. Deoxygenation may occur in the presence of a hydroprocessing catalyst. A condensable portion of the pyrolysis gases is condensed to form low oxygen biomass-derived pyrolysis oil.

  • Patent number: 8367882
    Abstract: Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones, cyclic ethers and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of oxygenated hydrocarbons, such as alcohols, ketones, aldehydes, furans, carboxylic acids, diols, triols, and/or other polyols, to C4+ hydrocarbons, cyclic ethers, alcohols and/or ketones, by condensation and/or deoxygenation. The oxygenated hydrocarbons may originate from any source, but are preferably derived from biomass.

  • Patent number: 8367881
    Abstract: A method is described for generating useful chemical intermediates from biomass using a novel pyrolysis reactor that utilizes the inherent thermal properties of carbon under compression as the biomass is subjected to sequential or concurrent temperature ramps. The ramps are sufficient to volatilize and selectively create different components, while the pressure application aids the selective decomposition of the biomass.

  • Patent number: 8361186
    Abstract: The invention provides for methods, devices, and systems for pyrolyzing biomass. A pyrolysis unit can be used for the pyrolysis of biomass to form gas, liquid, and solid products. The biomass materials can be selected such that an enhanced biochar is formed after pyrolysis. The biomass can be pyrolyzed under specified conditions such that a selected biochar core is formed. The pyrolysis process can form a stable biochar core that is inert and/or resistant to degradation. The biochar or biochar core can be functionalized to form a functionalized biochar or functionalized biochar core. Functionalization can include post-pyrolysis treatments such as supplementation with microbes or physical transformations including annealing and/or activation.

  • Patent number: 8362307
    Abstract: Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of mono-oxygenated hydrocarbons, such as alcohols, ketones, aldehydes, furans, carboxylic acids, diols, triols, and/or other polyols, to C4+ hydrocarbons, alcohols and/or ketones, by condensation. The oxygenated hydrocarbons may originate from any source, but are preferably derived from biomass.

  • Patent number: 8350103
    Abstract: The present disclosure is directed to processes for the direct conversion of lipidic biomass fuelstock to combustible fuels. In particular, the disclosure provides a process for the direct conversion of animal fats to transportations fuels suitable as replacement for petroleum-derived transportation fuels. In an example, the method comprises the steps of hydrolyzing a lipidic biomass to form free fatty acids, catalytically deoxygenating the free fatty acids to form n-alkanes, and reforming at least a portion of the n-alkanes into a mixture of compounds in the correct chain length, conformations, and ratio to be useful transportation fuels. Particularly, the product prepared comprises mixtures of hydrocarbon compounds selected from the group consisting of n-alkanes, isoalkanes, aromatics, cycloalkanes, and combinations thereof.
