Polymers are common materials of household appliance; as a result, there is great concern about the toxic compounds which maybe produced from these in the case of fire. Typical polymer-based products used in homes-poly (ethylene terephthalate), Nylon6, Nylon66, polystyrene, polypropene, and polyethylene products have been selected to identify pyrolysis gases for adsorption equilibrium study. Pyrolysis gases from heating the samples of polymer-based products were analyzed by thermogravimetric analysis/ automatic thermal desorption/ gas chromatography/ masss pectrometry. On the basis of the adsorption equilibrium data, activated carbon was more efficient than silica gel and zeolite 13X in the adsorption of the pyrolysis gases. Adsorption uptakes of the pyrolysis gases of aromatic, alkane, alkene, alcohol, ketone, epoxide, and acid gases on activated carbon were observed to be in the range of (10 to 50) ppm, and the adsorption uptake of acid gases was the highest. The regression model for the equilibrium isotherm data using the Freundlich equation was also developed in this study.
