The methane content in the hydrogen used in gasoline hydrogenation is high
Thread Content
Due to the interruption in feed, the gasoline unit operated in cycle mode for 6 hours; after the reaction temperature was increased, feed was gradually restored to normal levels. The methane content in the recycled hydrogen was found to be 10%, and help is sought to understand the reason for this

Thank you. By the way, during the cycling process, is it the increase in CO that leads to more methane production? What is the reason for the increase in co.?
It turns out that the hydrogen added contained it! Analyze the composition of your new hydrogen! It was originally added to the hydrogen zone; moreover, the longer the circulation time, the lower the purity of the hydrogen! There will also be some light hydrocarbons included in the cycle!
