WebReforming is a key step of the XTL process to produce syngas (CO and H 2 ). Syngas can be synthesized using three processes: steam reforming (SR), CO 2 reforming (dry reforming), … WebIt occurs when a substoichiometricfuel-air mixture is partially combustedin a reformer, creating a hydrogen-rich syngaswhich can then be put to further use, for example in a fuel cell. A distinction is made between thermal partial oxidation(TPOX) and catalytic partial oxidation(CPOX). Principle[edit]
WebThe Braun Purifier process plants utilized a primary or tubular reformer with a low outlet temperature and high methane leakage to reduce the size and cost of the reformer. Excess air was added to the secondary reformer to reduce the methane content of the primary reformer exit stream to 1–2%.
