A method for producing a fuel composition, including the following steps: providing special gas containing combustible substances; reforming a first part of the special gas by producing synthesis gas; producing dimethyl ether from the synthesis gas by producing a reaction mixture containing a dimethyl ether; separating methanol from the reaction mixture and producing a methanol-reduced dimethyl ether mixture; and bringing together a second part of the special gas with the methanol reduced dimethyl ether mixture in order to obtain the fuel composition.

Operation of a thermochemical regenerator at a controlled ratio of recycled flue gas to reforming fuel provides formation of fuel species that permit a higher flame temperature upon combustion of the resulting combustible mixture.

A method for the conversion of organic waste and/or biological waste into combustible products includes: feeding a first flow having organic waste and/or biological waste: performing a pyrolysis of the first flow to obtain one or more liquid pyrolysis products, one or more gaseous pyrolysis products, and one or more solid pyrolysis products; mixing the one or more solid pyrolysis products with a first aqueous flow, and subjecting the mixture to oxidation to obtain oxidation products; taking a first gaseous flow from the oxidation products; subjecting the one or more gaseous pyrolysis products to reforming, thereby obtaining one or more reforming products, taking a second gaseous flow from the reforming products, and subjecting the first gaseous flow and the second gaseous flow to catalytic hydrogenation, to obtain at least one first combustible.

Systems and methods are disclosed for pyrolysis of waste feed material. Some systems include a main retort and a secondary retort. Syngas is produced by pyrolysis in the main retort, and is then mixed with combustion air and ignited, in some cases to produce energy. Carbon char travels to the secondary retort and is exhausted from the system through an airlock.

Disclosed are methods useful in applications relating to blast furnace processes. The methods of the present invention provide enhanced deposition inhibition of particulate matter in top-pressure recovery turbines. The methods of the present invention comprise adding nitrogen-containing compounds to a top-pressure recovery turbine, inhibiting deposition of solids formed from blast furnace gas on top-pressure recovery turbine components.

The present invention relates to net-zero hydrogen plants and methods of operating said plants having a lower cost and much larger scale compared to electrolysis driven plants utilized to produce green hydrogen.

The present invention relates to methods of preparing carbon monoxide (CO) and hydrogen (H.sub.2) by reacting biomass, a biomass component (e.g., lignin, ligno-cellulose, cellulose, hemiceullose or combination thereof) or a carbohydrate from any source with a polyoxometalate catalyst such as H.sub.5PV.sub.2Mo.sub.10O.sub.40, or solvates thereof, in the presence of a concentrated acid, under conditions sufficient to yield carbon monoxide (CO); followed by electrochemical release of hydrogen (H.sub.2). The carbon monoxide (CO) and hydrogen (H.sub.2) may be combined in any desired proportion to yield synthesis gas (Syngas). The present invention further relates to methods for preparing H.sub.2, CO and formic acid/formaldehyde from biomass, a biomass component and/or from carbohydrates.
