영문 초록

The effects of various parameters, such as adsorption temperature, interstitial velocity, concentration of adsorbates and aspect ratios(L/D) of the fixed bed, on the adsorption characteristics referring to single and binary component were studied in a fixed bed of an activated carbon. For the single component, the break point decreased with increasing the adsorption temperature, interstitial velocity and concentration of adsorbates. Interstitial velocity, concentration of adsorbates and adsorption temperature had considerable influence upon the MTZ and LUB that obtained through the breakthrough curves. An adsorption isotherm of benzene and toluene was determined with single component, Langmuir, Freundlich and Langmuir-Freundlich isotherm agreed with experimental data fairly well. For the binary component, the adsorption breakthrough curve of key component (toluene) was sigmoidal as in the case of the single component system. However, the breakthrough curve of non-key component(benzene) was entirely different from that of the single component adsorption process. The magnitude of roll up increased with increasing concentration of adsorbates and aspect ratio of the fixed bed, and decreased with increasing interstitial velocity.
