Technology for producing sulfuric acid from gypsum at low temperatures
Thread Content
We are looking for solutions and methods related to the production of sulfuric acid from gypsum. We are currently interested in technologies for producing sulfuric acid at low temperatures, as this approach requires less energy compared to high-temperature conversion processes. Does anyone among you have any information on this topic or can recommend any manufacturers? It would be useful for everyone to learn and discuss this； The technology I am aware of at present is not yet mature; I hope everyone will participate actively. Thank you ；
There is now a new method for producing acid from gypsum, requiring only a temperature of 870 degrees. It is patented; I’m not sure what temperature level you consider to be considered low-temperature acid production
We are conducting experiments on producing acid using gypsum at a low temperature of 350°C; we don’t have any specific data yet. I’m not sure what the principle behind using 870°C is – is it the same as that used at the high temperature of 1100°C?
