摘要： The disclosed technology provides processes for producing hydrogen that is renewable, has negative carbon intensity, and is associated with net water production. The hydrogen is economically, environmentally, and socially superior to conventional hydrogen via steam reforming of natural gas or electrolysis of water. Some variations provide a process for manufacturing carbon-negative hydrogen and optionally activated carbon, comprising: feeding biomass into a first heated vessel or zone to generate dried biomass and a first recovered water stream; feeding the dried biomass into a second heated vessel or zone to pyrolyze the dried biomass, generating a biocatalyst and a biogas; feeding the biocatalyst, the first recovered water stream, and biogas to a third heated vessel or zone for biocatalytic conversion, thereby generating H2, CO, and optionally activated carbon; and recovering the hydrogen. The H2 is carbon-negative hydrogen characterized by a carbon intensity less than 0 kg CO2e per metric ton H2.

摘要： Processes, systems, and methods for producing combustible gas from wet biomass are provided. In one aspect, for example, a process for generating a combustible gas from a wet biomass in a closed system is provided. Such a process may include growing a wet biomass in a growth chamber, moving at least a portion of the wet biomass to a reactor, heating the portion of the wet biomass under high pressure in the reactor to gasify the wet biomass into a total gas component, separating the gasified component into a liquid component, a non-combustible gas component, and a combustible gas component, and introducing the liquid component and non-combustible gas component containing carbon dioxide into the growth chamber to stimulate new wet biomass growth.

摘要： A hydrogen-rich hydrocarbon fuel gas can be separated into a methane fuel stream and a hydrogen product stream. The methane fuel stream can be fed to a methane fuel fired furnace, combustion of the methane fuel stream can produce a carbon-dioxide-rich flue gas, and a carbon capture process can be performed on the carbon-dioxide-rich flue gas. The hydrogen product stream can be fed to a hydrogen fired furnace or elsewhere. Combustion of the hydrogen product stream in a hydrogen fired furnace can generate a flue gas the is low in carbon dioxide. Electrolysis of water obtained from the hydrogen fired furnace flue gas can produce hydrogen for a desired use, such as fuel for the hydrogen fired furnace, and can produce oxygen for enriching the fuel gas fed to the methane fuel fired furnace.

摘要： A system and method of producing synthesis gas and bio-oil from biomass. The method comprises producing, in a gasification unit, synthesis gas from a carbonaceous feedstock, optionally cooling the synthesis gas discharged from the gasification unit, channeling the synthesis gas towards a hydrothermal processing unit, wherein the hydrothermal processing unit is configured to process a biomass feedstock contained in a pressurized water stream, transferring, in the hydrothermal processing unit, heat from the synthesis gas to the biomass feedstock, and producing a hydrothermal product from the biomass feedstock in the pressurized water stream.

摘要： A process and/or system for producing fuel that includes providing biogas, removing carbon dioxide from the biogas, transporting the upgraded biogas to a hydrogen plant; providing the transported upgraded biogas and fossil-based natural gas as feedstock for hydrogen production. The carbon intensity of the fuel is less than 11 gCO2-eq/MJ, at least in part because carbon dioxide removed from the biogas and carbon dioxide from hydrogen production is captured and stored.

摘要： A process for the production of hydrogen comprising the steps of subjecting a gaseous mixture comprising a hydrocarbon and steam and having a steam to carbon ratio of at least 2.6:1, to steam reforming in a gas-heated reformer followed by autothermal reforming with an oxygen-rich gas in an autothermal reformer to generate a reformed gas mixture, increasing the hydrogen content of the reformed gas mixture by subjecting it to one or more water-gas shift stages in a water-gas shift unit to provide a hydrogen-enriched reformed gas, cooling the hydrogen-enriched reformed gas and separating condensed water therefrom, passing the resulting de-watered hydrogen-enriched reformed gas to a carbon dioxide separation unit to provide a carbon dioxide gas stream and a crude hydrogen gas stream, and passing the crude hydrogen gas stream to a purification unit to provide a purified hydrogen gas and a fuel gas.

摘要： A process and a plant for cooling a synthesis gas produced by catalytic steam reformation of a hydrocarbonaceous feed gas, which is cooled by heat exchange with boiler feed water for its conversion into steam, by separating the resulting aqueous condensate, wherein the further cooling is effected in that the gas passes through several series-connected cooling stages and comprises the heat exchange with the feed gas, with degassed and non-degassed boiler feed water for generating the steam required for the steam reformation, and with ambient air, and wherein condensate obtained after the last cooling stage is separated from the gas and the gas is discharged for the further treatment, wherein at least after a further cooling stage upstream of the last cooling stage a hot aqueous condensate is separated from the gas.
