  • Patent number: 10392564
    Abstract: A bio-product such as biochar, bio-coal, bio-oil, coke, and/or activated carbon material is formed by processing a starting biomass material comprising water-laden material. The starting biomass material is heated to below or above an autoignition temperature through a rotary compression unit (RCU) by generating steam through releasing unbound and bound waters in the biomass thus forming a bio-product. The biomass material being processed may be, without limitation, a woody or non-woody biomass material, such as cellulosic material and/or grain. The process can also form bio-oil from pyrolysis vapors which can be processed to other bio-products.

  • Patent number: 10208264
    Abstract: A formulation and methods for making high energy organic fuels that incorporate suspended metal particles with metal particle sized ranging from 33 nm to 5 micron. The hybrid organic fuels contain superior density and/or energy content to conventional liquid organic fuels. These hybrid organic fuels used in combination with metal particle afford fuels with 5 to 80% more net heat of combustion (based on volume). These fuels should extend the distant range for jets, liquid rocket engines, SCRAM jet engines, and improve energy content in fuel-air explosive applications such as fuel-air explosives and in the Multi-Effects Weapons System (MEWS) where the fuel is used both for propulsion and explosive effects.

  • Patent number: 8784095
    Abstract: Techniques, systems, apparatus and material are disclosed for generating oxygenated fuel. In one aspect, a method of producing an oxygenated fuel from biomass waste for use in a combustion system includes dissociating the biomass waste to produce one or more carbon donors. The biomass waste produced carbon donors are reacted with an oxygen donor to produce the oxygenated fuel comprising oxygenated carbon. Reacting the carbon donors with the oxygen donors includes applying waste heat recovered from an external heat source to the reaction of carbon donors and oxygen donor. The oxygenated fuel is combusted in the combustion system.

  • Patent number: 8784661
    Abstract: Techniques, systems, apparatus, and materials are disclosed for generating multi-purpose liquid fuel for isolating contaminants and storing energy. In one aspect, a method of producing a liquid fuel includes forming a gaseous fuel (e.g., by dissociating biomass waste using waste heat recovered from an external heat source). Carbon dioxide emitted from an industrial process can be harvested and reacted with the gaseous fuel to generate the liquid fuel. A hazardous contaminant can be dissolved in the liquid fuel, with the liquid fuel operating as a solvent or continuous phase for a solution or colloid that isolates the hazardous contaminant from the environment. The hazardous contaminant can include at least one of a carbon donor and a hydrogen donor.

  • Patent number: 8747797
    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: 8748679
    Abstract: A method for producing synthetic fluids from TGFA's harvested from genetically modified seed crops in which all of the fatty acids in the TGFA's from the seeds of a crop have the same carbon atom chain length, preferably C12 or C14, and the synthetic fluids produced by the method. The TGFA's are hydroprocessed to cleave the fatty acids from the glycol backbone and to hydrodeoxygenate and isomerize the fatty acids to form single carbon chain length isoparaffins having a controlled degree of branching with minimum cracking. Controlled mixtures of hydrocarbon components, in which each hydrocarbon component of the mixture has a different single carbon atom chain length, are produced.

  • Patent number: 8748678
    Abstract: A synthetic fuel formula using a blend of High Density Synthetic (HDS) (e.g. Decalin and Tetralin), and Low Density Synthetic (LDS) (e.g. Synthetic Paraffinic Kerosene—SPK) is disclosed. This HDS and LDS blend has been shown to be useful as a jet, rocket and diesel fuel of standard density, and under low temperature conditions. The inventions described herein relate to 100% synthetic hydrocarbon fuels derived from various carbonaceous materials such as, but not limited to, biomass, municipal waste, natural gas, and coal. This 100% synthetic fuel can be universally used for both jet and diesel fuels. It meets Joint Battlefield Use Fuel of the Future (J-BUFF), or Single Battlefield Fuel (SBF) strategic requirements. The commercial advantage of the present invention is that it can be prepared from commercial available fuel stocks or co-processed using currently available chemical processes.
