Sulfur anti-oxygen leakage catalyst
Thread Content
One-third of the anti-oxygen leakage catalyst is filled in the upper part of the first-stage sulfur recovery converter. What is the function of this anti-oxygen leakage catalyst?
Could you explain it in more detail? What is the principle?
In simple terms, within the Claus reactor, the catalyst not only accelerates the reaction between hydrogen sulfide and sulfur dioxide, but it also accelerates the reaction between sulfur dioxide and oxygen to produce sulfur trioxide. As a result, sulfur trioxide reacts with the alumina present in the catalyst, thereby reducing the surface activity centers of the catalyst； Secondly, the oxygen-proof catalyst utilizes the principle of exothermic reaction with oxygen; it is also used indirectly to raise the temperature of the bed in the primary reactor. The mechanism for removing oxygen involves the reaction of ferrous oxide with oxygen to produce ferrous sulfate, which then reacts with hydrogen sulfide in the presence of the catalyst to form ferrous sulfide, thus creating a cycle
Is this catalyst used in sulfur units?
