Partial oxidation

In the partial oxidation of a stoichiometric fuel-air mixture is combusted in a reformer part and there is a hydrogen-rich synthesis gas, which can be used for example, in the fuel cell.

A distinction is made between Thermal Partial Oxidation ( TPOX ) and Catalytic Partial Oxidation ( CPOX ). In TPOX these reactions depends on the air speed run off at 1200 ° C and more. CPOX at the required temperature by the use of a catalytic medium at 800 to 900 ° C. Whichever technique is used for reforming, is dependent on the sulfur content of the fuel used. If the sulfur content below 50 ppm can CPOX be used. A higher proportion of sulfur would poison the catalyst too strong, so the TPOX method is used for these fuels.
