Abstract

The sorption capacity of the selected adsorbents was determined - silica gel CSL (coarse-pored silica gel lump) and synthetic zeolite CaA according to the standards of aromatic and n-paraffin hydrocarbons using the cryoscopic method. The amount of adsorbed substance in weight percent for each portion of the filtrate is converted into grams, summed up and referred to 100 g of the adsorbent. After that, the silica gel was washed with distilled water until the reaction to the Cl– ion was negative, unloaded onto filtered paper, and left to dry in the open air. The solution was passed in a chromatographic column through an adsorbent. The amount of adsorbed substance A was calculated. Type A synthetic zeolites include zeolites with radii: KA (0,3 nm), NaA (0,4 nm) and CaA (0,49 nm). CaA zeolite adsorbs hydrocarbons and alcohols of normal structure only (regardless of the chain length) due to the size of the input window corresponding to the size of their critical diameters The synthesized zeolites are powders and in order to use them under dynamic conditions, they are granulated with the addition of a binder, usually natural clays, and molded into tablets, cylinders, or balls. The sorption capacity of the synthetic zeolite CaA for n-hexane from the liquid phase under dynamic conditions is given. As can be seen from the given data, benzene is practically not adsorbed by CaA zeolite, but is adsorbed by silica gel. Moreover, CSL silica gel activated with hydrochloric acid has a higher capacity.
