PROCESS FOR HYDROCARBON PYROLYSIS WITH A SPATIALLY SEPARATE HEATING ZONE AND REACTION ZONE INSIDE THE REACTOR SPACE
A process can be utilized to produce hydrogen and pyrolysis carbon from hydrocarbons where the hydrocarbons are converted into hydrogen and carbon in a reactor at temperatures of 1000° C. or more and the reactor has at least two electrodes that are at a distance from one another in a flow direction of the hydrocarbons. To avoid carbon deposits in a region between the electrodes, which can lead to failure of a heating system, the carbon particles may be introduced into the reactor in countercurrent to the hydrocarbons and may be heated in a heating zone between the electrodes to a temperature above a decomposition temperature of the hydrocarbons at such a mass flow that a reaction zone in which the hydrocarbons are converted into hydrogen and carbon is spatially separated in a flow direction of the carbon particles from the heating zone.
Catalytic membrane reactor, methods of making the same and methods of using the same for dehydrogenation reactions
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.
METHOD OF RECOVERING A HYDROGEN-ENRICHED PRODUCT AND CO2 IN A HYDROGEN PRODUCTION UNIT
Processes for producing a hydrogen-enriched gas stream are described. A hydrocarbon containing feed is processed in a hydrogen production process unit, and the synthesis gas formed is subjected to a water gas shift reaction. The shifted synthesis gas is sent for processing to recover hydrogen and carbon dioxide. The hydrogen and carbon dioxide recovery processes involve separating a purified hydrogen product stream and a purified carbon dioxide stream from the shifted synthesis stream and recycling synthesis gas to the reforming feed after recovery of CO.sub.2 and H.sub.2, thereby avoiding carbon slip from the process and lowering the overall carbon intensity.
