DETERMINATION OF SORPTION CAPACITY OF ORGANIC VAPORS ON ACTIVATED MESOCARBONS

Popis výsledku v původním jazyce

Specific surface of adsorbent is one of the key factors governing its application. Proposed paper deals with alternative experimental method based on weight registration during adsorption of pure organic vapors on tested samples. Thermogravimeter TGA-HP50 has been used for sorption experiments, where activated mesocarbon microbeads were the sorbent and vapors of benzene, toluene, acetone and cyclohexane were used as organic adsorbate. Primary data has been actual weight of the tested sorbent and absolute pressure of organic vapor. Solid sorbents have been prepared by chemical activation of pyridine insoluble matters (PI) using potassium hydroxide. Coal tar pitch as raw material was thermally treated together with Lewis acids (FeCl3, AlCl3) as catalyticagents. Temperature of activation was 850oC. Experimental data were fitted by Langmuir model of adsorption isotherm. Specific surface was determined from evaluated parameters.
