Patent ID: 7998456

Claim:
A process for the production of hydrogen from the catalytic partial oxidation of a hydrocarbonaceous feedstock with molecular oxygen over a partial oxidation catalyst, which process comprises: contacting a first mixture of the hydrocarbonaceous feedstock and molecular oxygen with an overall oxygen-to-carbon ratio in the range of from 0.3 to 0.8 with the partial oxidation catalyst to convert the feedstock to a hydrogen-comprising gas during a reaction time interval; and contacting a second mixture of the hydrocarbonaceous feedstock and molecular oxygen with an oxygen-to-carbon ratio in the range of from 1.0 to 10 with the partial oxidation catalyst during a regeneration time interval, in which process the regeneration time interval is in the range of from 2 to 10 seconds and the ratio of the reaction time interval to the regeneration time interval is at most 40.
