I would like to ask the experts and experienced professionals: why is the catalyst used in the sulfuric acid converter in solid form rather than liquid form? Thank you! If a liquid is used, there are no issues such as catalyst pulverization. When the vanadium content is low, it can be added directly from the outside, eliminating the need to stop the operation to replace or add new catalyst Could liquid catalysts be the next focus of research and development in the sulfuric acid industry? Please leave your valuable comments or suggestions, etc
Check the operating conditions of the catalyst before proposing a solution
Thank you for your reply. Isn’t there any special liquid whose temperature can reach 630–700 degrees? Or reduce the catalyst ignition temperature to 300-350 degrees.
If the ignition temperature of the catalyst is reduced to an appropriate level so that the heat generated by the reaction can be removed in a timely manner, is this approach theoretically feasible?
By optimizing and improving the current catalyst, it can be brought to a liquid state at high temperatures, allowing for continuous cyclic reactions similar to those in an absorption tower; at low temperatures, it returns to a solid state (i.e., its original form as a catalyst), during which further transformation reactions can take place.
At the moment, there isn’t any. At the same temperature, solids present less resistance, and corrosion is easier to address, which represents a great advantage
Even with a liquid catalyst, what should be done first regarding the sulfuric acid impurities?
The mechanism of vanadium catalysts used in the current contact method also involves a carrier phase, with the active components on the surface of the carrier being in a molten state.
