Process for producing hydrogen
Patent
·
OSTI ID:7177637
A process is claimed for supplying hydrogen to a hydrogen-consuming process including catalytically partially oxidizing hydrocarbon to produce a carbon monoxide- and hydrogen-containing gas, catalytically reacting water with the carbon monoxide- and hydrogen-containing gas to produce a carbon dioxide- and hydrogen-containing gas, centrifugally compressing the carbon dioxide- and hydrogen-containing gas to at least 180 psia carbon dioxide partial pressure and contacting it with an absorbing liquid containing diisopropanolamine and a cyclotetramethylene sulfone, catalytically reacting the absorber effluent gas at conditions to react hydrogen with carbon oxides to produce methane and passing the resultant hydrogen-containing gas to the hydrogen-consuming process. 5 claims, 2 drawing figures.
