Partial Oxidation » GSTC

Partial Oxidation. Partial oxidation (POX), or gasification, is a chemical reaction that occurs when a mixture of a hydrocarbon feedstock and a sub-stoichiometric amount of pure oxygen (O 2) are reacted together, producing a syngas stream with a typical H 2 /CO ratio range of 1.6 to 1.8.. The hydrocarbon feedstock is fed into the POX reactor (see figure below), where the carbon in the .
