Abstract: A method for producing a fuel includes transporting one or more pressure vessels containing pressurized biogas from a first location to a second location, and removing biogas from the one or more pressure vessels at the second location. The fuel production process is improved by controlling the decanting flow rate to provide a total decant time greater than 30-40 minutes, by actively heating biogas contained within the one or more pressure vessels, or some combination thereof.

Abstract: A method for providing a fuel includes providing a partially purified biogas at a first processing site, where the partially purified biogas is produced by multiple biogas sources and/or from multiple feedstock sources. The partially purified biogas is compressed, fed to a mobile tank, and transported by vehicle to a second processing site. At the second processing site, which may also receive biogas from a plurality of biogas sources, the partially purified biogas is further processed to produce a fuel or fuel intermediate.

Abstract: A process is provided for forming a fuel or a fuel intermediate from two fermentations that includes feeding an aqueous solution comprising a fermentation product from a first bioreactor to a second bioreactor and/or a stage upstream of the second bioreactor, which also produces the fermentation product. The aqueous solution may be added at any stage of the second fermentation and/or processing steps upstream from the second bioreactor that would otherwise require the addition of water. Accordingly, the product yield is increased while fresh/treated water usage is decreased.

Abstract: The present invention provides a process for producing one or more products for use as a transportation or heating fuel. In various embodiments the process comprises treating a cellulosic feedstock in one or more processing steps that release extractives from the feedstock. A solids-liquid separation is subsequently conducted on the process stream comprising the extractives and solids. An aqueous stream comprising one or more of the extractives may be fed to an anaerobic digester to produce crude biogas from which one or more impurities may optionally be removed. In various embodiments the process further comprises providing a solids stream to a thermal process. A product produced or derived from the thermal process may displace a product made from fossil fuel. One or more products obtained or derived from at least one of the foregoing process steps are provided for use as a transportation or heating fuel. In various embodiments the process enables advantaged fuel credit generation.

Abstract: A process for producing one or more products from a lignocellulosic feedstock comprising treating the lignocellulosic feedstock to produce sugar in one or more stages comprising addition of acid, base or a combination thereof and introduction of heat. The addition of the acid, base, or a combination thereof produces a salt. The sugar is fermented to produce a fermentation product and the fermentation product is recovered. A stream comprising the salt is treated by wet oxidation with the introduction of heat. A stream comprising salt resulting from the wet oxidation is provided for use as a salt product or a process chemical for introduction within the process. Heat from the wet oxidation may be supplied to any stage of the process in which heat is introduced.

Abstract: The present disclosure provides a process for forming a biogenic carbon-based fuel or a fuel intermediate from biogenic carbon dioxide and hydrogen. At least a portion of the biogenic carbon dioxide and hydrogen is subjected to a reverse water gas shift reaction that produces at least carbon monoxide. The carbon monoxide so produced, the biogenic carbon dioxide and the hydrogen are introduced, together or separately, to a biologic or chemical conversion process to produce the fuel or fuel intermediate.

Abstract: A method for providing upgraded biogas includes feeding a stream of biogas into a biogas upgrading system in order to remove carbon dioxide from the stream of biogas. The biogas upgrading system, which may be based on absorption, adsorption, membrane permeation, and/or cryogenics, provides a stream of upgraded biogas and a tail gas stream. The tail gas stream, which may be CO2-rich, is enriched with natural gas so that it is combustible in medium-BTU equipment. The upgraded biogas is used for transportation use and/or the generation of fuel credits. Accordingly, both the tail gas and the upgraded biogas are used effectively and at lower cost.

Abstract: The present invention provides a process for producing a fermentation product from a lignocellulosic feedstock. The process comprises soaking a lignocellulosic feedstock in an aqueous solution to produce a soaked feedstock. The soaked feedstock is at least partially dewatered and the at least partially dewatered feedstock is subjected to pretreating in the presence of sulfur dioxide, sulfurous acid or a combination thereof to produce a pretreated feedstock composition. The pretreated feedstock composition is fed to an enzymatic hydrolysis in which the concentration of dissolved solids fed to the enzymatic hydrolysis is at least 50% (w/w) of the concentration of dissolved solids in the pretreated feedstock composition. The cellulose in the pretreated feedstock composition is hydrolyzed with cellulase enzymes in the presence of the dissolved solids to produce glucose. The glucose is fermented to produce the fermentation product.

Abstract: Embodiments of the invention provide a process in which a gas comprising biomethane having a heating value of about 350-950 BTU/cubic foot is introduced to a pipeline system at a combination point that is downstream of natural gas in the pipeline system having a heating value of at least about 950 BTU/cubic foot. This produces a mixed gas downstream of the combination point. At least a portion of the mixed gas downstream of the combination point is withdrawn for use by a user that combusts the mixed gas to generate heat and/or electricity. A corresponding amount of natural gas is withdrawn at an upstream location for use as a transportation fuel, a fuel intermediate or as a feedstock for producing a fuel. The process can enable fuel credit generation.
