FIELD: separation of organic compounds.
SUBSTANCE: invention concerns adsorption isolation processes and can be used when isolating monomethyl-substituted paraffins from hydrocarbon mixtures. Gist of invention resides in that a method for adsorption isolation with simulated moving bed designed for isolation of monomethyl-substituted paraffin C8-C14 is realized by passing initial mixture through adsorbent bed at air/fuel ratio between 0.5 and 1.5, 30-120°C, and operation cycle time 20-60 min. Thereafter, adsorbed monomethyl-substituted paraffin is selectively isolated from adsorbent bed when in contact with desorbent. Initial mixture containing monomethyl-substituted paraffins further contains at least another acyclic nonlinear hydrocarbon with the same number of carbon atoms and less than 5% of normal C8-C14-paraffins. Adsorbent includes silicate.
EFFECT: increased selectivity of isolation.
