Partial Oxidation

In the case of partial oxidation, a substoichiometric fuel-air mixture is partially combusted in a reformer and a hydrogen-rich synthesis gas is formed, which can be reused in the fuel cell, for example.

A distinction is made between thermal partial oxidation (TPOX) and catalytic partial oxidation (CPOX). At TPOX, these reactions depend on the air number at 1200 ° C and above. At CPOX, the required temperature is reached by using a catalytic medium at 800 to 900 ° C. Which technology is used for reforming depends on the sulfur content of the fuel used. If the sulfur content is less than 50 ppm CPOX can be used. A higher sulfur content would poison the catalyst too much, so the TPOX process is used for these fuels. Edit source text
