Nitrogen was the other adsorbate since air is composed of nitrogen by 79%. As adsorbents one in-house adsorbent; SBA-15 and three commercial adsorbents; HiSiv-3000 (ZSM-5 zeolite), activated carbon cloth, mesoporous activated carbon were used. Experiments of constant volume technique were performed in order to obtain adsorption isotherms of methyl chloride and nitrogen with the adsorbents mentioned above up to 1.6 arm in the temperature range of 21.5 and 80°C. Langmuir, Freundlich, Sips and Toth isotherm models were fitted to these isotherms. By using the Toth isotherm parameters adsorption isosteres were obtained. Henry's Law constants and heat of adsorption values were calculated. Expected working capacities for pressure swing adsorption (PSA), vacuum swing adsorption (VSA), temperature swing adsorption (TSA) were obtained and feasibility of these processes was discussed. The binary system behavior was also predicted for HiSiv-3000 and SBA-15 by using Extended Langmuir and Ideal Adsorbed Solution models. Methyl chloride adsorption breakthrough curves with HiSiv-3000 and SBA-15 for vacuum swing adsorption application was produced. The effects of modeling parameters such as temperature, inlet concentration, flow rate and bed length were investigated. It was concluded that mesocarbon is the best adsorbent to separate methyl chloride from air. Carbon cloth has the lowest heat of adsorption for methyl chloride. Prediction of binary system behavior showed that nitrogen adsorption is negligible. Mesocarbon shows the highest expected working capacities for PSA, VSA and TSA. VSA and TSA were found to be two promising processes for separation of methyl chloride from air. (Abstract shortened by UMI.)113 p.enEngineering, Chemical.Thesis
