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 method for providing a fuel includes removing hydrogen sulfide and/or carbon dioxide from biogas to provide partially purified biogas, which is filled in a mobile storage system. The partially purified biogas is transported to a centralized processing facility, in the mobile storage system, by truck, rail, or ship. At the centralized processing the partially purified biogas is further processed, either to produce a fuel that is renewable or has renewable content, or to produce renewable natural gas, which is used to produce the fuel that is renewable or has renewable content.

Abstract: A method for providing a fuel includes providing biogas from a plurality of biogas sources, the biogas from each biogas source produced in a process comprising filling a vessel with raw biogas or partially purified biogas to a pressure of at least 1500 psig and transporting the filled vessel to a centralized processing facility by vehicle. A fuel is produced in a fuel production process that includes feeding the biogas transported to the centralized processing facility to a biogas upgrading system that is configured to provide a carbon dioxide removed from the biogas. The removed carbon dioxide is provided for transport by vehicle and/or pipeline and/or sequestered to offset greenhouse gas emissions attributed to compressing the biogas for transport.

Abstract: A process for hydrolyzing lignocellulosic biomass includes feeding lignocellulosic biomass into a pretreatment reactor, wherein the pretreatment reactor has a headspace charged with sulfur dioxide previously used in the pretreatment of lignocellulosic biomass. In addition, acid comprising sulfur dioxide and/or sulfurous acid is fed into the pretreatment reactor (e.g., with the lignocellulosic biomass, separate from the lignocellulosic biomass, or a combination thereof) and the lignocellulosic biomass is heated. As the pretreated lignocellulosic biomass is discharged from the pretreatment reactor, at least a portion of the sulfur dioxide used in the pretreatment is retained in the headspace.

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: A method for upgrading biogas comprising methane and nitrogen, where the biogas is provided in at least one pressurized vessel at a pressure of at least 65 atm (6586 kPa). The method includes a pressure swing adsorption (PSA) cycle having a feed phase, where biogas is fed into a first adsorbent bed when the inlet end is open and the outlet end is closed, followed by a first depressurization phase, where a gas enriched in methane is withdrawn through the outlet end with the inlet end being closed. This gas enriched in methane can be pipeline quality and at pipeline pressures. A methane recovery phase is provided, which can improve methane recovery, wherein gas is withdrawn and the pressure drops to one or more lower values, and where this gas can be recycled for use in the feed phase, used in a regeneration phase, and/or fed to a second bed.

Abstract: A process and/or system for producing one or more biofuels, wherein biogas (e.g., partially purified biogas produced by removing water, hydrogen sulfide and/or carbon dioxide from raw biogas) is transported by vehicle in one or mobile vessels. De-pressurization of the mobile vessels provides a change in pressure that can be used to provide work, cooling, and/or increased pressure for the production process. Combustion of the biogas produces heat and/or power used to reduce a carbon intensity of the biofuel or biofuel intermediate.

Abstract: A process for producing ethanol from lignocellulosic biomass includes adding at least one of sulfur dioxide and sulfurous acid to the lignocellulosic biomass to provide an equivalent sulfur dioxide loading of at least 10 wt % sulfur dioxide to dry lignocellulosic biomass. The acidified lignocellulosic biomass is pretreated at a temperature above about 185° C. and for a pretreatment time less than about 10 minutes, to provide a pretreated biomass composition wherein the biomass is readily hydrolyzed by enzymes. Advantageously, sulfur dioxide from at least one of the flash stream and a stream derived from the flash is recovered and recycled back into the process.

Abstract: A method for providing renewable natural gas (RNG) includes removing hydrogen sulfide and/or carbon dioxide from biogas to provide partially purified biogas, which may be stored in a mobile storage tank. The partially purified biogas is transported to a biogas upgrading facility, at least partially by truck, rail, or ship. At the biogas upgrading facility, the partially purified biogas is further purified to provide the RNG, which can be injected into a distribution system (e.g., natural gas grid) and/or provided for use in transportation.
