of the natural gas–fed POX process. The oxygen fed to the system is sub-
stoichiometric such that both CO and CO

are formed in the system. A

POX is highly exothermic and raises the reactants to a high temperature.
The resulting reaction products, still in a reduced state, are then quenched
through the introduction of superheated steam. The addition of steam pro-
motes the combined water–gas shift and steam reforming reactions, which
further cools the gas. In most cases, and with sufcient preheating of the
reactants, the overall reaction is exotherm ...
