for the different aromatic compounds with this procedure is as follows benzene 10 n xylene 9 5 o xylene 9 51 p xylene 9 32 and styrene 10 2 the procedure of example 1 was repeated using pinene turpentine after adsorption the mordenite carbonized at 200 u00b0 c the carbon was oxidized under a 500 u00b0 c 2 hours thermal soak which regenerated the dealuminated mordenite for further adsorption vapors from naphthalene were passed through an adsorption bed of dealuminated mordenite which had been previously soaked at 500 u00b0 c for two hours after the bed showed a weight gain of 8 8 the dealuminated mordenite carbonized during a thermal soak at 200 u00b0 c the sorbent was regenerated with thermal soaking at 500 u00b0 c to remove the carbon by oxidation in air vapors from dichlorobenzene were passed through an adsorption bed of dealuminated mordenite which had been previously soaked at 500 u00b0 c for two hours during the regeneration the sorbent carbonized and emitted a fume which was acid to indicator paper the sorbent was further regenerated by oxidation of the carbon with a thermal soak at 500 u00b0 c examples 1 5 show that aromatic compounds two ring aromatic compounds chlorinated aromatic compounds and cyclical hydrocarbon containing two different rings are readily adsorbed by dealuminated mordenite and with thermally soaking the sorbent carbonizes the sorbent is completely regenerated with an additional thermal soak the carbonization indicates that the sorbate is destroyed during the regeneration cycle the following examples show the general applicability of the described method.
