Process for Producing Hydrogen Product Having Reduced Carbon Intensity
A method for producing hydrogen product having a low carbon intensity is provided. The method includes the steps of: (a) converting a hydrocarbon feedstock to a hydrogen product using a hydrocarbon reforming process; (b) providing at least some of the required energy for the hydrogen production process from a biomass power plant; and (c) processing one or more flue gas streams from the biomass power plant in a carbon capture unit to reduce CO.sub.2e emissions. The hydrogen product has a carbon intensity preferably less than about 1.0 kg CO.sub.2e/kg H.sub.2, more preferably less than 0.45 kg CO.sub.2e/kg H.sub.2, and most preferably less than 0.0 kg CO.sub.2e/kg H.sub.2.
Nickel-iron catalyst and methods of making and using same
A catalyst includes a derivative of an iron-containing clay which includes at least one member selected from the group consisting of a nickel-iron bimetallic structure according to XRD and a nickel-iron bimetallic oxide structure according to XRD. The catalyst can be used in various reactions, such as carbon dioxide methanation and dry reforming of methane and carbon dioxide to produce syngas.
POWER PRODUCTION WITH COGENERATION OF FURTHER PRODUCTS
The present disclosure relates to cogeneration of power and one or more chemical entities through operation of a power production cycle and treatment of a stream comprising carbon monoxide and hydrogen. A cogeneration process can include carrying out a power production cycle, providing a heated stream comprising carbon monoxide and hydrogen, cooling the heated stream comprising carbon monoxide and hydrogen against at least one stream in the power production cycle so as to provide heating to the power production cycle, and carrying out at least one purification step so as to provide a purified stream comprising predominately hydrogen. A system for cogeneration of power and one or more chemical products can include a power production unit, a syngas production unit, one or more heat exchange elements configured for exchanging heat from a syngas stream from the syngas production unit to a stream from the power production unit, and at least one purifier element configured to separate the syngas stream into a first stream comprising predominately hydrogen and a second stream.
SMART HYDROGEN PRODUCTION FOR DRI MAKING
The invention relates to the production of direct reduced iron, DRI, where a hydrogen direct reduction is synergistically operated in the context of an industrial plant. The hydrogen reduction operates with reducing gas comprising at least 85 vol. % hydrogen, and receives a make-up hydrogen stream. At least part of the make-up hydrogen stream is produced on site. by at least one of (i) electrolysis means configured to produce hydrogen from steam recovered from one or more components of the industrial plant and/or from steam generated using waste heat and/or hot gases emitted by the one or more components; and (ii) gas shift reactor means configured to convert CO-bearing gas emitted by at least one component of the industrial plant into hydrogen and to remove CO.sub.2.
Process for H2 and syngas production
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.
METHODS AND APPARATUSES FOR HYDROGEN PRODUCTION
The present disclosure provides systems and methods for hydrogen production as well as apparatuses useful in such systems and methods. Hydrogen is produced by steam reforming of a hydrocarbon in a gas heated reformer that is heated using one or more streams comprising combustion products of a fuel in an oxidant, preferably in the presence of a carbon dioxide circulating stream.
PROCESS FOR PRODUCING LOW CARBON HYDROGEN
Low carbon hydrogen will play a crucial role in decarbonization of chemical complexes and manufacturing facilities. Depending on the application, different grades of low carbon hydrogen might be requiredfuel grade (90-99% H2 purity) or chemical grade (>99% H2 purity). The current invention describes a hydrogen production process based on autothermal reforming and CO2 capture to produce low carbon hydrogen with hydrogen rich offgas as part of the feedstock.
