The adsorption behaviour and long-term stability of diphenoldichlorosilane (DPDSCI) coated zeolite was investigated in a column study by studying the toluene adsorption performance and material regeneration at various temperatures. Computer modelling (CXTFIT and MATLAB) was adapted to explore the adsorption mechanism, including the calculation of the axial dispersion coefficient and maximum adsorption capacity. The results indicate that DPDSCI coated zeolite presented a higher adsorption capacity towards toluene than that found in previous batch experiments. Under high flow rates, temperature had little influence on the adsorption behaviour. Regeneration tests prove that this material may be..
