The issue of new catalysts
Thread Content
The newly purchased vanadium catalyst was tested for arsenic content at the factory, and the level of arsenic found was more than twice higher than that in the old catalyst that had been in use for ten years. I would like to ask everyone: shouldn’t a vanadium catalyst contain no arsenic at all when it leaves the factory?
Has the new catalyst been put into use? How are the performance metrics?
Oh, this shouldn’t happen; let’s do a pre-saturation check
Already in use; pre-saturation is not good. The conversion rate per segment is acceptable, but the overall conversion rate remains unsatisfactory
