In the event of a short-term shutdown, the downstream units can use hydrogen for short-term reduction before feeding materials in again; however, the processing volume should not be too high. It is necessary to increase the hydrogen and water-carbon ratio as well as the temperature at the outlet of the conversion process, and feed materials online for reduction. After that, samples should be taken to check whether the methane content at the conversion outlet meets the required standards! Once qualified, you can increase the processing volume!
Agree with what was said above. As long as the operation is stopped in a reducing atmosphere, it is not necessary to use a reducing atmosphere when starting up again.
