摘要：

Prior to the technical use of natural gas, toxic and corrosive components need to be removed. This work provides results from dynamic fixed-bed experiments for the adsorption of sulfurous compounds, CO2 and H2O from carrier gas (CH4 or N2) on two adsorbents (zeolite 5A, silica-alumina-gel) used in industrial applications. The breakthrough curves were measured at ambient conditions (298K, 1.3bar) in a trace level concentration range up to 2000mol-ppm. Adsorption isotherms were derived using mass balances and a simple linear driving force model was fitted to the curves. Good agreement of experimental data and model calculation was obtained.
