Hydrogen composition in catalytic reforming?

Hydrogen C1 to C6. Purity over 80%, free of

The circulating hydrogen in fixed-bed semi-regenerative catalytic reforming should, in principle, contain no carbon monoxide or carbon dioxide. However, in current fluidized-bed continuous regeneration reforming, since coking treatment is carried out during the regeneration process, the catalyst may absorb trace amounts of carbon monoxide and carbon dioxide, which are then carried into the reactor and mixed with the recycled hydrogen. But these trace amounts of carbon monoxide and carbon dioxide react under hydrogen conditions to form small amounts of water and methane. The recycled hydrogen in the reforming process is primarily composed of hydrogen, with a purity ranging from 80 to 95%; this value can vary to some extent, or even significantly, depending on the process and operating conditions. Other components include small hydrocarbons such as methane and ethane, as well as trace amounts of water.
