👉 The term "desulfurizer" refers to a chemical process that is used to remove sulfur from the atmosphere. When sulfur dioxide (SO2) emissions are released into the air, it reacts with oxygen in the presence of sunlight to form sulfuric acid (H2SO4). This reaction produces SO2 gas and can be harmful to the environment if not properly controlled. Desulfurization is a process that involves adding an oxidizing agent such as H2O2 or KMnO
