The present invention includes a method for converting renewable energy source electricity and a hydrocarbon feedstock into a liquid fuel by providing a source of renewable electrical energy in communication with a synthesis gas generation unit and an air separation unit. Oxygen from the air separation unit and a hydrocarbon feedstock is provided to the synthesis gas generation unit, thereby causing partial oxidation reactions in the synthesis gas generation unit in a process that converts the hydrocarbon feedstock into synthesis gas. The synthesis gas is then converted into a liquid fuel.

Integrated refinery processes and systems for generating hydrogen by direct decomposition of hydrocarbons. The integrated processes and systems can be used to capture carbon and sulfur in solid form, reducing carbon dioxide and sulfur oxide emissions. The processes include reacting sour gas with a metal-based sorbent in a reactor to produce sulfur-bearing solids and water, and to partially reform hydrocarbons in the sour gas to produce hydrogen-rich syngas; and cracking remaining hydrocarbons thermally with or without the presence of a catalyst to produce hydrogen and solid carbon.

A process for steam or dry reforming of hydrocarbons in a reforming reactor, comprising the steps of: (a) passing a feedstock, comprising one or more hydrocarbons together with steam and/or CO.sub.2, through a first catalytic zone at an elevated temperature, to form a partly reformed process gas, wherein the first catalytic zone comprises one or more elongate conduits, each containing reforming catalyst; and (b) passing the partly reformed process gas through a second catalytic zone at an elevated temperature, so as to form a reformed gas stream, wherein the second catalytic zone comprises one or more elongate conduits, each containing reforming catalyst; wherein the process further comprises the combustion of a fluid fuel with a combustion-sustaining medium in an exothermic combustion region, to form a hot combustion products stream, wherein the exothermic combustion region is adjacent to and laterally surrounds each of the second catalytic zone elongate conduits.

A method for producing synthesis gas may involve introducing a hydrocarbon-containing coke-oven gas and a carbon dioxide-containing converter gas into a first reaction zone where hydrogen present in the hydrocarbon-containing coke-oven gas reacts at least partly with carbon dioxide to form water, which reacts thermally with hydrocarbon to form synthesis gas containing carbon monoxide and hydrogen. The method may further involve introducing an oxygen-containing gas in a second reaction zone, and using the oxygen-containing gas and some hydrogen from the first reaction zone to produce thermal energy. Still further, the method may involve supplying the thermal energy produced in the second reaction zone to the first reaction zone.

A catalytic membrane reactor and methods of operating and producing the same are provided that efficiently produces highly pure hydrogen (H.sub.2) from ammonia (NH.sub.3) as well as operates according to other chemical conversion processes. In one embodiment, a tubular ceramic support made from porous yttria-stabilized zirconia has an outer surface that is impregnated with a metal catalyst such as ruthenium and then plated with a hydrogen permeable membrane such as palladium. An inner surface of the ceramic support is impregnated with cesium to promote conversion of ammonia to hydrogen and nitrogen (N.sub.2). The resulting catalytic membrane reactor produces highly pure hydrogen at low temperatures and with less catalytic loading. Therefore, ammonia can be used to effectively transport hydrogen for use in, for example, fuel cells in a vehicle.
