Effect of oxygen content on sulfur dioxide formation during regenerative charring
Thread Content
How does the oxygen content during the regeneration and charring process affect the formation of sulfur dioxide and sulfur trioxide?
During the regeneration and charring process, the oxygen content affects the amount of sulfur dioxide produced. When there is an adequate supply of oxygen, sulfides are completely oxidized to sulfur dioxide, resulting in a large amount of this substance being produced ； When the oxygen content is insufficient, sulfides can only be partially oxidized to sulfur dioxide, resulting in a corresponding decrease in its production. Furthermore, the level of oxygen content also affects the formation of sulfur trioxide. At high oxygen levels, sulfur trioxide can be produced by oxidizing sulfur dioxide ； At low oxygen levels, the reaction that produces sulfur trioxide is inhibited, resulting in a corresponding decrease in its production. -
