Partial Oxidation » GSTCGlobal Syngas
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
