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.

A method for processing feedstock is described, characterized in that incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock. In some embodiments the incoming feedstock is comprised of mixed solid waste, such as municipal solid waste (MSW). In other embodiments the incoming feedstock is comprised of woody biomass. In some instances, the incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% and greater suitable for conversion into biogenic carbon Fischer Tropsch liquids. The high biogenic carbon Fischer Tropsch liquids may be upgraded to biogenic carbon liquid fuels. Alternatively, the incoming feedstock is processed to selectively recover plastic material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% or less.

A process to optimize carbon from carbon dioxide in synthesis gas used to produce synthetic chemicals and fuels. The process involves using captured carbon dioxide from any source and controlling its reformation with gaseous hydrocarbons to produce a synthesis gas with a specific carbon monoxide to hydrogen ratio suitable for selected intermediate and end products. The carbon from carbon dioxide displaces fossil carbon and lowers the carbon intensity of the products. The process uses any hydrocarbon gas, fossil or renewable, and may utilize steam to optimize the synthesis gas composition. The invention also includes recycling gases and the generation of heat, steam and electrical power for the reformer and other equipment, significantly reducing the carbon footprint of the plant.

Separation of carbon dioxide from the exhaust of an internal combustion engine, the production of hydrogen from water, and reformation of carbon dioxide and hydrogen into relatively high-octane fuel components.

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.

A unique process and catalyst is described that operates efficiently for the direct production of a high cetane diesel type fuel or diesel type blending stock from stochiometric mixtures of hydrogen and carbon monoxide. This invention allows for, but is not limited to, the economical and efficient production high quality diesel type fuels from small or distributed fuel production plants that have an annual production capacity of less than 10,000 barrels of product per day, by eliminating traditional wax upgrading processes. This catalytic process is ideal for distributed diesel fuel production plants such as gas to liquids production and other applications that require optimized economics based on supporting distributed feedstock resources.

The invention discloses novel diesel fuel compositions including a renewable diesel component, a fossil diesel component and an oxygenate component, as well as methods for manufacture and use of a combination of a renewable diesel component, and an oxygenate component for reducing particulate matter emissions.

A method and a system for improving the GHG emission reduction performance of fuels, heating mediums and combustion materials and for enriching agricultural land with C-containing humus.

Processes for producing high biogenic concentration Fischer-Tropsch liquids derived from the organic fraction of municipal solid wastes (MSW) feedstock that contains a relatively high concentration of biogenic carbon (derived from plants) and a relatively low concentration of non-biogenic carbon (derived from fossil sources) wherein the biogenic content of the Fischer-Tropsch liquids is the same as the biogenic content of the feedstock.
