摘要
PURPOSE: The pretreatment method of a sulfur oxide selectivity absorber and a sulfur oxide selectivity absorber pre-treated thereby are provided to efficiently remove a sulfur oxide in a fraction in which the sulfur oxide is included and increase the breakthrough adsorption capacity of the sulfur oxide and breakthrough drainage by passing through a treatment process before adsorption. CONSTITUTION: The silica based pretreatment method of a sulfur oxide selectivity absorber includes a step for performing an acid treatment on the silica surface. The pretreatment method additionally includes a step for drying the acid-treated silica surface, and the drying temperature is 100 ~ 200=. The acid includes any one of sulfuric acid, nitric acid, hydrochloric acid, acetic acid, and hydrofluoric acid or a mixture thereof. The concentration of the acid is 0.1 ~ 10M. The contact time of the silica surface and acid is 1 minutes ~2 hours.
