This post was last edited by Pfz2867 on 2011-10-7 at 15:43 RT. . . . . . . . How much is imported and how much is domestically produced? How many years will it last, and what will the conversion rate be? What is the loading capacity? Thank you
Domestic catalysts have a higher bulk density and are generally sold by ton, while foreign catalysts are usually sold by volume, at around 5–6 cubic meters per ton-hour of acid produced (these values are approximate for reference only). The cost of purchasing foreign catalysts for a 300,000-ton sulfuric acid production plant is approximately over 4 million. Regarding the service life of catalysts abroad, the first period is generally shorter, with a guarantee of around 5 years, while the subsequent periods can last 8 to 10 years. The time at home is shorter. The conversion rate is generally the rate specified by the client and provided to the manufacturer, who then calculates the loading amount based on this rate. According to the current national standards, a conversion rate of 99.9% is achieved.
Reply to 2# A Sha: Is the amount of catalyst used in the production of sulfuric acid from pyrite and sulfur roughly the same? What are the advantages of imported catalysts over domestic ones in this application? Is it quick to light the stove?
Reply to 3# Pfz2867: I’m not very familiar with the processes related to pyrite. Regarding discussions on catalysts, there are some posts on the forum that you can refer to.
Reply to 4# A Shie: I’ve taken a look. I just want to know the investment required for imported catalysts
Reply to 2# A Shi: “Abroad, it’s usually sold by cubic volume; generally, it’s 5–6 cubic meters per ton of acid per hour. Is that really necessary?” Isn’t it a promotion? (L)
Reply to 6# Pfz2867: What I meant is the amount of acid loaded per unit of time. This figure is related to the capacity of the device and the design capabilities of the equipment, and it is not a scientific metric. The total catalyst loading for a sulfuric acid plant with an annual production capacity of 300,000 tons is around 160 cubic meters.
Is it effective to use cesium-containing catalysts in producing acid from 300,000 tons of pyrite?
It is recommended to use imported catalysts, which require less loading and have a longer service life. 300,000 tons is approximately 160-180 cubic meters
