Title: Desulfurizing method
Inventor: KIN KISHUN
IPC: B01D53/46
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To efficiently desulfurize by an easy method with a simple device event at a rather low temp. by introducing gas to be treated containing sulfur compds. into plasma to bring the gas into contact with a catalyst. SOLUTION: A reactor 1 consists of a plasma producing part 11 and a catalyst contact part 12 formed in a cylindrical quartz tube of specified dimension. In a process to introducing gas into the plasma, the reactivity of sulfur compds. such as H2S, SO2 and SO3 present in the gas to be treated is increased by imparting energy by the plasma. Further, these compds. are efficiently oxidized by various kinds of radicals, ions or the like having high activity in the plasma. In a catalyst contact process, the activation energy is decreased by a catalyst and the oxidation of the sulfur compds. is caused even at a low temp. Therefore, by combining the two processes above described, the sulfur compds. can be efficiently oxidized at a low temp. and easily desulfurized.
