I’m sorry, regarding basic questions about catalysts
Thread Content
Dear DXs, what is the average usage time of mercury chloride catalysts? Including the total usage time for both the front end and back end
Generally over 10,000 hours
1KG－1.5KG/tVCM
Generally, it is 8,000 to 12,000 hours; with proper use, it can reach over 20,000 hours
20,000 hours is the threshold for discarding it due to mercury content, right?:lol
The catalyst is mercuric chloride, not mercury chloride! It uses a process with old and new catalysts connected in series... which can prevent excessive temperature rise! It’s usually changed every six months... Since the vehicle has to be parked, it’s a good opportunity to do a thorough repair!
In chemistry, the divalent mercury chloride is called mercuric chloride; mercuric subchloride is merely an old term for it. Monovalent mercury chloride is called mercurous chloride. It’s not the case that they are all replaced collectively during maintenance periods; it takes a day per unit, and that would be extremely busy. Replacements can be made at any time during the production process. This post was last edited by yu*nyang_01 on 2009-3-28 23:23.]
It depends on the purity of the feed gas; if the feed gas is pure, it can be used for a longer period of time. If the feed gas contains SP impurities, its useful life is shorter. We generally use it for around 8,000 hours
The service life of the converter catalyst is related to the total amount of material processed by it; the greater the amount processed, the shorter the service life, and vice versa. This does not include cases of catalyst poisoning or failure due to operational errors.
Generally, a new catalyst is used in the second stage for about 3,000 hours before being moved to the primary stage for another 5,000 hours; the total usage time is around 8,000 hours. The decision on whether to discard it is made by analyzing the mercury content.
Thank you all up there:victory: :victory: :victory:
I heard quite early on that there are mercury-free catalysts that can significantly extend the usage time; I wonder if anyone has used them
Generally, 8,000 to 12,000 hours
