Breakthrough modeling and experimental design for o -xylene dynamic adsorption onto clay material

摘要: The adsorption of o-xylene onto raw clay material in a fixed bed using thermal conductivity detector gas chromatography was investigated. Experimental and theoretical studies were established to evaluate the removal efficiency by on materials predict kinetic parameters. Column data describing at different conditions Bohart–Adams, Wolborska, Thomas, Yoon Nelson, dose–response, depth service time models. All used models satisfactory breakthrough curves. A suitable advection–dispersion–sorption (ADS) model has been also developed simulate measured data, based nature various equilibrium relationships solid–gas diverse descriptions mass transfer processes within adsorbent particle. experiments can be fitted with high correlated coefficient R 2 = 0.996.
