Abstract (en)
[origin: WO2008053006A1] The present invention provides a process for the production of hydrogen, wherein during a first time interval a hydrocarbonaceous feedstock (3) is converted to a hydrogen-comprising gas (5) by mixing the feedstock with an amount of molecular oxygen (4) to form a first mixture comprising feedstock and molecular oxygen with an overall oxygen-to-carbon ratio in the range of from 0.3 to 0.8 and contacting the first mixture with a partial oxidation catalyst (6) and interrupting the contacting of such first mixture with the partial oxidation catalyst during a second time interval, wherein from the start and during at least part of the second time interval no hydrocarbonaceous feedstock or molecular oxygen is supplied to the partial oxidation catalyst, in which process the ratio of the first time interval over the second time interval is in the range of from 0.05 to 5. The invention further provides a process for operating an internal combustion engine and use of the produced hydrogen for reducing NOx to molecular nitrogen and water.
