The adsorption breakthrough test of hydrogen chloride was performed by loading zeolite 13X pellet (molecular sieve 13X, Aldrich Co., USA), a commercial absorbent, onto a fixed bed reactor (height 15 cm, inside diameter 0.5 cm). The breakthrough test was carried out by changing various experimental conditions such as inlet flow rate (0.5, 1, 1.5, 2 l/min), HCl concentration (200, 350, 500, 650 ppm), reaction temperature (30, 50, 70, 90C), and reaction pressure (1, 5, 10, 15, 20 bar) with considering the retention time and space velocity. After evaluating the adsorption and the desorption characteristics of HCl on the MS-13X, the consecutive cyclic test was carried out with optimum condition. The optical, physical, and chemical characteristics of MS-13X were analyzed using BET, XRD, SEM, EDX, and TGA before and after breakthrough tests.
