Abstract
A process of catalytic partial oxidation of a hydrocarbon fuel with an oxidant to produce partially-oxidized reaction products including hydrogen, with simultaneous in-situ coke removal. The process involves feeding a hydrocarbon fuel and an oxidant to a reactor in a fuel-rich feed ratio; reacting the fuel and oxidant for a fuel-rich cycle-time so as to produce a partially-oxidized reaction product; varying the fuel feed, or the oxidant feed, or both feeds to produce a fuel-lean feed to the reactor; maintaining the fuel-lean feed for a fuel-lean cycle-time sufficient to reduce coke deposits while maintaining a substantially constant yield of partially-oxidized reaction product; and alternating between the fuel-rich and fuel-lean operating cycles.
