How should a catalyst be properly put into use in an isothermal hydrogenation reactor for hydrogen production after it has been replaced?
Thread Content
We plan to replace the catalyst in the isothermal hydrogenation reactor during operation; since the catalyst is in a sulfided state, there is no need to stop production for sulfidation. Currently, there is only one adiabatic hydrogenation reactor, which uses natural gas as raw material to maintain production. During normal production, we use catalytic dry gas as the main feedstock with natural gas as a supplement. But once the catalysts in the isothermal hydrogenation reactor have been replaced, how do we put them into use?
For catalysts in the sulfided state, fill the small gas vessel with water to around 50 degrees, slowly open the inlet of the isothermal reactor, pressurize to ensure airtightness, and then slowly increase the temperature for drying. Once the outlet temperature reaches 220 degrees, introduce the catalytic dry gas! Control the air pocket pressure to control the outlet temperature! Control the adiabatic reactor temperature using isothermal voltammetry!
