摘要： A chemical reactor including reformer tubes for reforming a first feed stream including a hydrocarbon gas and steam. The chemical reactor includes one or more reformer tubes arranged to being heated by an electrically driven heat source. The reformer tube includes a first inlet for feeding said first feed stream into a first reforming reaction zone of the reformer tube, and a feed conduit arranged to allow a second feed stream into a second reforming reaction zone of the reformer tube. The second reforming reaction zone is positioned downstream of the first reforming reaction zone. The feed conduit is configured so that the second feed stream is only in contact with catalyst material in the second reforming reaction zone. A process of producing CO rich synthesis gas at low S/C conditions.

摘要： Provided herein is process of obtaining hydrogen from a blue hydrogen production facility that meets a target carbon intensity (CIT), the process comprising: generating hydrogen from non-renewable feedstock; capturing and sequestering fossil CO2 derived from the non-renewable feedstock; and at least partially powering hydrogen production with renewable electricity, the renewable electricity being derived from biomass in which biogenic carbon produced therefrom (e.g., carbon dioxide, char and the like) is captured and sequestered; and wherein the use of the renewable electricity in the hydrogen production allows the carbon intensity of the hydrogen produced therefrom to be reduced sufficiently so that the target carbon intensity (CIT) is achieved.

摘要： A process for producing syngas that uses the syngas product from an oxygen-fired reformer to provide all necessary heating duties, which eliminates the need for a fired heater. Without the flue gas stream leaving a fired heater, all of the carbon dioxide produced by the reforming process is concentrated in the high-pressure syngas stream, allowing essentially complete carbon dioxide capture.

摘要： A low carbon-emission hydrogen production process may be achieved by first separating carbon dioxide from a reformer syngas stream, followed by separating the carbon dioxide-depleted syngas stream using a semi-permeable membrane to produce a hydrogen-enriched permeate and a hydrogen-depleted retentate. The hydrogen-enriched permeate is purified to produce a hydrogen product and a hydrogen-depleted tail gas stream. The hydrogen-depleted retentate stream may be recycled to the feed and the hydrogen-depleted tail gas stream may be used as fuel in the reformer burners.

摘要： A process for producing methanol, wherein a make-up gas stream from a reformer unit is admixed with a hydrogen-containing stream from a hydrogen recovery stage to obtain a hydrogen-rich synthesis gas, which is combined with a residual gas stream and the combined stream is passed through a bed of a methanol synthesis catalyst at elevated pressure and elevated temperature to obtain a product stream comprising methanol and the residual gas stream and wherein the product stream is cooled to remove methanol from the residual gas stream. Wherein a portion of the residual gas stream is removed as a purge gas stream and a portion of the hydrogen-rich synthesis gas stream is removed and combined with the purge gas stream to obtain a mixed synthesis gas stream and the mixed synthesis gas stream is sent to the hydrogen recovery stage to produce the hydrogen-containing stream.

摘要： The disclosure relates to methods, systems, and apparatus arranged and designed for converting non-methane hydrocarbon gases into multiple product gas streams including a predominately hydrogen gas stream and a predominately methane gas steam. Hydrocarbon gas streams are reformed, cracked, or converted into a synthesis gas stream and methane gas stream by receiving a volume of flare gas or other hydrocarbon liquid or gas feed, where the volume of hydrocarbon feed includes a volume of methane and a volume of non-methane hydrocarbons. The hydrogen contained in the syngas may be separated into a pure hydrogen gas stream. A corresponding gas conversion system can include a super heater to provide a hydrocarbon feed/steam mixture, a heavy hydrocarbon reactor for synthesis gas formation, and a hydrogen separator to recover the hydrogen portion of the synthesis gas. The gas conversion system can have a modal design such that it can operate to form hydrogen gas or alternatively operate to form synthetic natural gas with the same unit operation components.
