water-to-hydrogen ratio
Thread Content
The requirement that the water vapor ratio at the inlet of the hydrogen production converter should not exceed 7 is based on what considerations?
It should be the water vapor ratio, the ratio of water vapor to hydrogen
During reduction, the water-to-hydrogen ratio used should be greater than 0.5 and less than 7; the purpose of adding steam is mainly to improve the gas flow, prevent excessive reduction of the catalyst, and avoid carbon formation caused by the infiltration of natural gas. In my opinion, if the water-to-hydrogen ratio is greater than 7, the reduction effect is poor, which prolongs the time required to reduce the catalyst; moreover, using too much steam also increases energy consumption.
Which part of the restoration are you referring to?
Transformation and intermediate reduction occur together
Being too large may lead to excessive reduction of the medium-temperature catalyst, while being too small will definitely result in poor reduction effects!
