Reactive diluent fluid () is introduced into a stream of synthesis gas (or 'syngas') produced in a heat-generating unit such as a partial oxidation ('POX') reactor () to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted () with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit () such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.

Process and apparatus for the production of synthesis gas

Reactive diluent fluid () is introduced into a stream of synthesis gas (or 'syngas') produced in a heat-generating unit such as a partial oxidation ('PDX') reactor () to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted () with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit () such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.

A method and apparatus for the production of hydrogen-rich gas are provided. The method and apparatus prevent over-reduction of iron oxide-based shift catalyst by introducing an oxidative stream along with a carbon monoxide containing gaseous feed stream from a catalytic steam reformer to the catalyst bed region and thereby limits structural deterioration of the catalyst. Various sources may provide the oxidative stream including a shift catalyst bed region and a selective oxidation catalyst region.

Method and apparatus for the production of hydrogen-rich gas

The present invention is an apparatus arranged to maximize heat utilization for a hydrocarbon steam reforming process to produce synthesis gas. The apparatus comprises a refractory lined vessel with partition walls that divide the inside of the vessel into (1) a combustion chamber(s) containing one or more burners, and (2) convection chambers used as a means to remove combustion products from the combustion chamber through one or more openings at the opposite end of the burner end. The combustion chamber contains one or more reformer tubes in which a mixed-feed of hydrocarbon and steam flow co-current with combustion products and receive direct radiant heat from the combustion flame through the tube wall. The convection chambers contain a tube-in-tube device filled with catalyst in the annuli. The mixed-feed in the annuli flows counter-current with combustion products and the hot product synthesis gas, and thereby substantially lowers the temperature of the combustion and product gases before the gases exit the furnace. High emissivity materials or walls are used inside the convection chambers to enhance the heat transfer from the flue gas to the reformer tubes.

Apparatus and method for hydrocarbon reforming process

A burner is provided which includes a plurality of burner subunits that each share a single air supply, a single fuel supply and a single control system. Each burner subunit has a plurality of air orifices and a plurality of fuel orifices of sufficient quantity and of a cross-sectional area to control a transverse heat flux profile of the burner. The burner subunits are spaced with respect to one another to control a longitudinal heat flux profile of the burner. The single air supply and said single fuel are adapted to provide an air-fuel mix that ensures the transverse and the longitudinal heat flux profiles are maintained at different fuel and air input rates. A burner of similar design using premixed air and fuel is also disclosed.

Burner assembly for delivery of specified heat flux profiles in two dimensions

An apparatus for a hydrocarbon reforming process includes a combustion chamber, a convection chamber in fluid communication with the combustion chamber, at least one burner disposed in the combustion chamber, a reaction chamber, a means for flowing a first mixed-feed through a first part of the reaction chamber, and a means for flowing a second mixed-feed through an annular portion of a second part of the reaction chamber, the second part being a tube-in-tube in fluid communication with the first part. The burner(s) generates a flow of a flue gas having a sensible heat from the combustion chamber to the convection chamber. The flow of the flue gas in the convection chamber is counter-currently with the flow of the second mixed-feed.

Apparatus and method for production of synthesis gas using radiant and convective reforming

Method for the production of methanol and hydrogen which comprises steam reforming a hydrocarbon-containing feed in a steam reforming zone to yield a synthesis gas comprising hydrogen, carbon monoxide, and carbon dioxide; introducing a first portion of the synthesis gas into a methanol synthesis zone to form methanol; reacting a second portion of the synthesis gas with steam to convert carbon monoxide to hydrogen and carbon dioxide to yield a shifted synthesis gas; cooling the shifted synthesis gas to yield a cooled shifted synthesis gas; separating the cooled shifted synthesis gas into a high-purity hydrogen product stream and a reject stream enriched in carbon dioxide; and introducing some or all of the reject stream into either or both of the steam reforming zone and the methanol synthesis zone.

Co-production of hydrogen and methanol from steam reformate

A process is provided for simultaneously producing a syngas product having a H /CO ratio of less than 2.5 and a hydrogen gas product. The process includes increasing an amount of carbon dioxide being fed to a secondary reformer with carbon dioxide extracted from: (a) an effluent from a primary reformer and (b) an effluent from the secondary reformer. An apparatus for performing the process is also provided.

Co-production of carbon monoxide-rich syngas wth high purity hydrogen

This invention relates to an improved process for the coincineration of municipal solid waste and municipal sewage sludge by dewatering the sludge, breaking it up into sufficiently small particles and employing oxygen enrichment of the combustion process. These small particles of sludge are introduced into the combustion zone above the grate in the combustion zone but at a distance above the grate no higher than that of the point of introduction of secondary air. This is accomplished without undesired excursions of flue gas flow rate and temperature.

Process for combusting dewatered sludge waste in a municipal solid waste

A process for the stabilization of heavy metals in the ash produced by the combustion of a heavy metals containing fuel, such as municipal solid waste, by introducing into the combustion system a phosphorous oxide specie or elemental yellow phosphorus. The additive can be introduced at any point in the system upstream of the particulate removal device employed in the system. If elemental phosphorus is used, it must be introduced at a point in the system where it will be exposed to an elevated temperature and oxygen, so as to be converted to a phosphorus oxide specie. When elemental phosphorus is introduced into the system downstream of the combustion zone, it is also effective to reduce the NO content of the flue gas.

Method of stabilizing heavy metals in ash residues from combustion

A method is disclosed for producing ammonia synthesis gas by splitting a methane stream, combusting a portion of the methane with steam and oxygen-enriched air, converting a second portion of the methane with steam in a reformation heated by the combustion products of the first portion and combining the two portions for the water gas shift reaction followed by adsorptive separation of contained carbon dioxide.

Production of ammonia synthesis gas

Carbon black is produced from a pyrolyzed hydrocarbon wherein pyrolysis is effected by combusting a synthesis gas containing hydrogen and carbon monoxide. The synthesis gas is produced from reforming a hydrocarbon fuel, wherein the reformation is heated by combusting carbon black effluent tail gas or indirect heat exchange of the hot tail gas.
