摘要
PURPOSE: A sulfur oxide selectivity absorber and a pretreatment method thereof are provided to effectively remove a sulfur oxide in a fraction in which the sulfur oxide is included by using a non-standardized porous silica and increase the breakthrough adsorption capacity of the sulfur oxide and a breakthrough drainage by presenting detailed absorber treatment conditions like the pore size of silica, a surface area, a surface processing method, and a heat treatment temperature. CONSTITUTION: A sulfur oxide selectivity absorber is based on silica, and the silica is porous silica having the pore size of 4 ~ 9nm. The surface area of the silica is 300 ~ 600m^2/g. The pore volume of the silica is 0.01 ~ 0.3cm^2/g. The pretreatment method of the sulfur oxide selectivity absorber includes a step for the heat treatment of the silica, and the heat treatment temperature is 100 ~ 300=. Preferably, the heat treatment temperature of the silica is 100 ~ 200=.
