  • 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: A method for producing a supercritical cryogenic fuel (SCCF) includes dissolving a hydrogen gas in fuel value proportions into a supercritical hydrocarbon fluid. The method is performed by placing a hydrogen gas and a hydrocarbon fluid at a pressure greater than the critical pressure of the hydrocarbon, placing the hydrogen gas and the hydrocarbon fluid at a temperature below or approximately equal to the critical temperature of the hydrocarbon forming the supercritical hydrocarbon fluid, and then mixing to dissolve the hydrogen gas into the supercritical hydrocarbon fluid. A system for performing the method includes a vortex mixer configured to turbulently mix the hydrogen gas and the supercritical hydrocarbon fluid. The supercritical cryogenic fuel (SCCF) produced by the method and the system includes the supercritical hydrocarbon fluid with a selected mole fraction of the hydrogen gas dissolved therein.

  • Patent number: 7473285
    Abstract: A method of making a liquid fuel from agricultural waste which may be animal manure, includes admixing agricultural waste with at least one material selected from the group consisting of hydrogen gas and water, at elevated pressure heating a mixture to about 300° C. to 400° C. for a predetermined time, subsequently cooling the mixture, and subsequently separating gas from liquid. The process produces a liquid fuel having a high heating BTU value per pound of fuel. The water preferably functions as both a solvent and the hydrogen donor for said agricultural waste. Corresponding apparatus is provided.

  • Patent number: 7455704
    Abstract: Fuels used may be derived from existing waste streams such as animal wastes and streams of discarded or unwanted animal byproducts generated at animal slaughterhouses. A method of processing organic waste products into fuel includes homogenizing the waste products. The waste products are heated and pressurized. Water is removed from the waste products. Selected constituent of the waste products are separated from the waste products into a waste stream. The waste stream is blended with a fuel to form a bio-fuel mixture.

  • Publication number: 20080250831
    Abstract: The invention is a process for treatment of brown grease, where the brown grease comprises water, food solids and free-oil. This process starts with the collection of the brown grease into a container. The brown grease's pH is adjusted with a chemical treatment to produce an adjusted brown grease phase. To the adjusted brown grease phase an anionic copolymer treatment mixture is added along with a cationic copolymer to form a reaction mixture. The reaction mixture reacts for a period of time, and during this time wastewater is discharged from the reaction mixture to produce resulting solids. The resulting solids are then transferred from the container for disposal or are processed further into a fuel or soil additive.
