Hydrogen is also commercially produced as a by-product of chemical processes (ethylene crackers、styrene、MTBE etc) or gasoline manufacturing (catalytic reforming).、Obtained by passing water vapors over heated iron、by electrolysis of water or by action of hydrochloric acid or sulfuric acid on iron or zinc、by hydrolysis of metal hydrides.、(1) Reaction of steam with natural gas (steam reforming) and susequent purification、(2) partial oxidation of hydrocarbons to carbon monoxide and interaction of carbon monoxide and steam、(3) gasification of coal、(4) dissociation of ammonia、(5) thermal or catalytic decomposition of hydrocarbons gases、(6) catalytic reforming of naphtha、(7) reaction of iron and steam、(8) catalytic reaction of methanol and steam、(9) electrolysis of water.、Hydrogen can be produced using diverse、domestic resources including fossil fuels、such as natural gas and coal (preferentially with carbon capture、utilization、and storage)、biomass grown from renewable、non-food crops、or using nuclear energy and renewable energy sources、such as wind、solar、geothermal、and hydroelectric power to split water. This diversity of potential supply sources is an important reason why hydrogen is such a promising energy carrier.、Hydrogen is produced on a laboratory scale from the action of an aqueous acid on a metal or from the reaction of an alkali metal in water ... These reactions can be carried out at room temperature. Hydrogen gas can also be produced on a laboratory scale by the electrolysis of an aqueous solution. Production of hydrogen through electrolysis is also used industrially. ... Hydrogen atoms can be produced in significant quantities in the gas phase by the action of radiation on or by extreme heating of H2 (3000 K).、Formulations、Preparations: Grades: Technical、pure、from an electrolytic grade of 99.8% to ultra-pure、with less than 10 ppm impurities.、Consumption Patterns: CHEMICAL INTERMEDIATE FOR AMMONIA、56%、PETROLEUM REFINING、25%、CHEMICAL INTERMEDIATE FOR METHANOL、7%、OTHER、12% (1980)、U.S. consumption of hydrogen in 1988: 49% as chemical intermediate for ammonia、37% in petroleum refining、8% as chemical intermediate for methanol、6% as other uses、U.S. Production: 2023: 20、000、000 - <25、000 lb、2022: 10、000 - <15、2021: 15、000 - <20、2020: 15、(1977) 8.48X10+10 CU FT、(1979) 9.93X10+10 CU FT、Daily Capacity: 4、197、260 thousands of cu ft、U.S. ... about 3 billion cu ft、yr、For more U.S. Production (Complete) data for Hydrogen (6 total)、U.S. Exports: (1977) 5.91X10+8 CU FT、(1979) 1.27X10+8 CU FT、General Manufacturing Information: All Other Basic Inorganic Chemical Manufacturing、Petroleum Refineries、All other Petroleum and Coal Products Manufacturing、Petrochemical Manufacturing、Miscellaneous Manufacturing、All Other Basic Organic Chemical Manufacturing、Industrial Gas Manufacturing、Hydrogen: ACTIVE、Production of hydrogen in usa alone now amounts to about 3 billion cu ft、yr.、Method of purification: by scrubbing with various solutions (especially the Girbitol absorption process). For very pure hydrogen、by diffusion through palladium.、More efficient methods than electrolysis for obtaining hydrogen from water are under investigation. One of these is thermochemical decomposition. Another is photochemical decomposition by solar radiation、either directly or via a solar power generator. Photolytic decomposition of water with platinum catalyst has been achieved. Hydrogen can also be obtained by photolytic decomposition of hydrogen sulfide with cadmium sulfide catalyst.、Most U.S. hydrogen production ... is used captively.、For more General Manufacturing Information (Complete) data for Hydrogen (7 total)。
