Steam-hydrocarbon reforming reactor with a reformer tube containing ceramic-supported catalyst pellets and metal foam particles. The ceramic-supported catalyst pellets have a porous support comprising one or more of alumina, calcium aluminate, and magnesium aluminate. The metal foam particles comprise Fe and/or Ni. The ceramic-supported catalyst pellets and metal foam particles may be layered or interspersed.

Steam-hydrocarbon reforming reactor

A system is set forth for the exothermic generation of soot depleted syngas comprising (i) reacting a hydrocarbon-containing fuel with an oxygen containing gas in a first reactor to produce the syngas and byproducts comprising CO, HO and soot; and (ii) introducing the syngas and byproducts into a second reactor containing a non-carbonaceous material that traps the soot for a sufficient time such that the majority of the byproduct soot is gasified via reaction with the byproduct COand/or HO to produce a syngas stream that is depleted in the soot. The system is particularly suitable for the practice of heat exchange reforming wherein a portion of the heat is recovered from the soot depleted syngas stream and used as at least a portion of the heat to facilitate the additional production of syngas via the (endothermic) catalytic reforming of natural gas and steam.

A method for protecting a welded pipe assembly from metal dusting and a welded pipe assembly suitable for performing the method. The welded pipe assembly comprises two pipes, weld material joining the two pipes and insulating material. The pipes are protected from metal dusting by a protective coating. The present invention is useful for conveying gases comprising carbon monoxide at temperatures greater than 425&#xb0; C. while preventing metal dusting of the welded piping assembly.

A tubular reactor for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert with cup-shaped structures having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.

A process for producing a hydrogen-containing product gas by catalytic steam-hydrocarbon reforming with an overall steam-to-carbon molar ratio between 1.5 and 2.4 for the process. The process stream is reacted in at least two prereformers prior to reaction in catalyst-containing tubes in a top-fired reformer furnace. The process stream is reacted adiabatically in the first prereformer, while the process stream is heated prior to being introduced into the second prereformer and/or the second prereformer is heated. The process avoids carbon formation on the catalyst in the catalyst-containing tubes in the primary reformer.

A process for producing a hydrogen-containing product gas with reduced carbon dioxide emissions compared to conventional hydrogen production processes. A hydrocarbon and steam are reformed in a reformer and the resulting reformate stream is shifted in one or more shift reactors. The shifted mixture is scrubbed to remove carbon dioxide to form a carbon dioxide-depleted stream. The carbon dioxide-depleted stream is separated to form a hydrogen-containing product gas and a by-product gas. A portion of the hydrogen containing product gas is used as a fuel in the reformer and a portion of the by-product gas is recycled back into the process. The process may optionally include reforming in a prereformer and/or an oxygen secondary reformer.

Steam-hydrocarbon reforming with reduced carbon dioxide emissions

The present invention relates to a method and furnace for generating straightened flames in a steam methane reformer or ethylene cracking furnace where fuel-staged burners are used. Fuel staging may be used for reducing NOx emissions. Criteria for generating straightened flames are provided. These criteria relate to oxidant conduit geometry and furnace geometry. Techniques for modifying the furnace and/or burners to achieve these criteria are also provided.

The second reformer section comprises catalyst-containing tubes for partially reforming a hydrocarbon stream. The catalyst-containing tubes in the second reformer section are disposed in a conduit for conveying flue gas from the first reformer section, thereby receiving heat from the flue gases.
