Methanol shift

When sulfidation is first initiated in methanol conversion, the water vapor ratio must be kept low. Just how low should it be, and how can the water vapor ratio be reduced?
No steam to be used; try to keep the moisture content in the feed material as low as possible

For sulfurization without driving the reaction, nitrogen and CS2 are used directly in reaction, with no water vapor present. For vulcanization while driving, it is necessary to control the water vapor ratio by lowering the temperature of the gas, thereby causing the water to condense.
I agree with you; using circulating nitrogen along with hydrogen, followed by the addition of carbon disulfide for vulcanization, is an effective and safe method, and it’s easy to control the bed temperature!

Reply to 5# 654262293: So does controlling the temperature at the outlet of the vaporization control scrubber reduce the water vapor ratio?
After the initial sulfidation process while the reactor is in operation, the water vapor ratio is quite low. During subsequent operations, the water vapor ratio of the gas introduced at the start of vaporization is also low; as long as no steam is introduced, the bed temperature can be kept within a low range
