Which reactor catalyst should be given priority protection when the dry gas hydrogen production plant is shut down?
Thread Content
When the dry gas hydrogen production plant is shut down, is it the converter catalyst that tends to coking? Is the medium-transformer reactor easier to reduce? How to prevent it?
It is of course carbon deposition in the conversion catalyst; therefore, when the conversion furnace has to be shut down urgently due to an outage, the first thing to do is to stop feeding material to the conversion furnace and close the valves that connect the hydrogen desulfurization unit to the conversion furnace. At this point, the converter contains only steam anymore – do you still think that the medium-temperature shift catalyst will be reduced?
(1) Preventing carbon deposition in conversion catalysts; (2) Preventing reduction in high-hydrogen-concentration environments for cobalt-molybdenum hydrogenation catalysts
Of course it’s the conversion catalyst; what was said on the second floor is correct
