How is the catalyst in each reactor protected during the startup, operation, and shutdown of the hydrogen production plant?
Thread Content
Our company’s hydrogen production plant is equipped with reactors such as isothermal reactors, adiabatic hydrogenation reactors, zinc oxide desulfurization reactors, reformers, and medium-temperature shift reactors. How can we protect the catalysts in these reactors during startup, operation, and shutdown? Please provide specific details! I’m a beginner, so I hope everyone can give me some guidance!

Your department has the technical documents; they should be quite detailed. Go and look for those technical documents. . . .
For the first three reactors, my experience tells me that it is essential to strictly control the composition of the feed gas in order to prevent overheating of the bed; any increase in temperature must be addressed promptly. When operating a conversion furnace, it is crucial to ensure a steady feed rate, and the water-to-carbon ratio should also be kept stable as much as possible. During an emergency shutdown, the injection time of steam must be sufficient; here we reduce it by half in 15 minutes and shut it off completely in half an hour.
