Abstract

An autothermal reformer according to the principles of the present invention comprises a first stage that selectively receives a fuel flow, a first oxidant flow, and a steam flow. The first stage has a first portion of a catalyst bed. The fluids within the first stage are routed through the first portion of the catalyst bed and react. There is a second stage downstream from and communicating with the first stage. The second stage receives the fluids from the first stage and also selectively receives a second oxidant flow. The second oxidant flow and the fluids received from the first stage flow through a second portion of a catalyst bed and further react.
