A process for the production of syngas comprising the steps of providing a feed gas comprising a hydrocarbon, carbon dioxide and optionally steam, contacting a flow of said feed gas with a metal oxide to form syngas, wherein the mole fraction of carbon dioxide or in the case the feed gas comprises steam, the sum of the mole fractions of carbon dioxide and steam, in the feed gas is between 0.3 and 0.7; and/or wherein the mole fraction of the hydrocarbon in the feed gas is between 0.3 to 0.5, wherein the feed gas is contacted with the metal oxide at a temperature of between 1050K and 1600K.

The present disclosure relates to a hydrogen reforming system including a reforming part configured to produce a reformed gas containing hydrogen by allowing a source gas and pure water to react with each other, a source gas supply line connected to the reforming part and configured to supply the source gas, a pure water supply line connected to the source gas supply line and configured to supply the pure water, a discharge line configured to discharge the reformed gas from the reforming part, and a heating part configured to selectively heat at least any one of the source gas and the pure water. The source gas and the pure water are to be supplied to the reforming part by using waste heat of the reformed gas discharged from the reforming part, thereby obtaining an advantageous effect of improving stability, reliability, and reforming efficiency.

A hydrogen generating device may include a water supply device for cartridges; a first hydrogen supply valve provided in a first hydrogen supply passage through which hydrogen gas is supplied from the first cartridge to a buffer tank; a second hydrogen supply valve provided in a second hydrogen supply passage through which hydrogen gas is supplied from the second cartridge to the buffer tank; and a main hydrogen supply passage for supplying hydrogen gas from the buffer tank to outside. For switching a hydrogen supply source from the first cartridge to the second cartridge, a controller may perform: a first process to stop supplying water to the first cartridge and supply water to the second cartridge with the second hydrogen supply valve closed, and a second process to open the second hydrogen supply valve to supply hydrogen gas from the second cartridge to the buffer tank.

Provided is an operation management system configured to manage delivery of a raw material from a raw material production base where the raw material including a hydride is produced to a plurality of dehydrogenation bases where the raw material is subjected to a dehydrogenation reaction to obtain a hydrogen-containing gas. The operation management system includes: an information acquisition unit configured to acquire first information on a dehydrogenation status in the plurality of dehydrogenation bases; and a delivery plan creation unit configured to create a delivery plan for delivering the raw material to the plurality of dehydrogenation bases on the basis of the first information.

A chemical plant comprising an off-gas treatment unit arranged to accept a hydrocarbon-containing off-gas stream, the off-gas treatment unit comprising sequentially: (i) an autothermal reformer, arranged to accept a hydrocarbon-containing fuel stream comprising hydrocarbons and steam and produce a reformed gas stream; (ii) a water-gas shift section arranged to accept said reformed gas stream and produce a shifted gas stream; and (iii) a CO2 removal unit arranged to accept said shifted gas stream and produce a CO2 rich stream and a decarbonised fuel stream; wherein said hydrocarbon-containing fuel stream is derived from said hydrocarbon-containing off-gas stream, steam and any supplemental fuel; wherein the chemical plant is arranged such that the decarbonised fuel stream is combusted instead of said hydrocarbon-containing off-gas stream.

A method for the suppression of soot formation during the partial oxidation of a hydrocarbon-containing gaseous feed, in the presence of steam and in an ATR reactor or in a POX reactor, the method comprising the addition of gaseous carbon dioxide to the hydrocarbon-containing gaseous feed before entry into the reactor. A method for determining a minimum steam to carbon ratio required for scot-free operation is also disclosed.

A non-transitory, processor readable medium stores instructions that, when executed by a processor, causes the processor to receive (1) an indication of a feed gas flow rate measured between a feed gas source and an internal combustion engine (ICE) and (2) an indication of an oxygen enriched air flow rate measured between an air separation unit (ASU) and the ICE. A measured equivalence ratio is determined based on a feed gas composition, the feed gas flow rate, and the oxygen enriched air flow rate. The instructions further cause the processor to generate at least one of a first signal to cause a change in revolution speed of the ICE, a second signal to cause a first flow control device to modify the feed gas flow rate, or a third signal to cause a second flow control device to modify the oxygen enriched air flow rate.

A plant, such as a hydrocarbon plant, is provided, which consists of a syngas stage for syngas generation and a synthesis stage where said syngas is synthesized to produce syngas derived product, such as hydrocarbon product. The plant makes effective use of various streams; in particular CO.sub.2 and H.sub.2. A method for producing a product stream, such as a hydrocarbon product stream is also provided.
