Who has used a reduced methanol catalyst?
A catalyst in its reduced state for methanol refers to a catalyst that is reduced outside the tower following the process carried out inside the tower, and then installed for use directly.
Both transformation and ammonia synthesis catalysts have pre-reduction catalysts, while methanol catalysts currently do not have pre-reduction catalysts. A company in Hunan reduces the methanol catalyst and then transports the reduced catalyst directly into the tower.
Which catalyst? Copper-based catalysts for methanol synthesis?
Yes, what we are talking about here is a methanol catalyst.
We filled it more than halfway under a nitrogen atmosphere
A complete reduction is not possible; only a partial pre-reduction can be achieved. Otherwise, transportation and loading must take place in a nitrogen atmosphere. We have used reduction methods, but the catalyst surface becomes passivated, and heating is required for further reduction after loading, although the time needed is shorter.
Only pre-reduction outside the tower is possible, and it can only proceed to the removal of physical water, combined water, and some impurities
External tower reduction is carried out in the same manner and for the same duration as the internal tower reduction process, with specialized transport vehicles used for loading.
