Kinetics of absorption of a mixture of aliphatic, aromatic, and unsaturated hydrocarbons from the gas phase onto polypropylene containing 5, 18, and 40% atactic polymer in its molecular lattice was studied. The kinetic parameters, equilibrium constant, and Gibbs energy of adsorption-desorption of the hydrocarbons were determined by zero-, first-, and second-order optimization of the solution of the multiparameter equation. These parameters were correlated with the adsorbent composition and the number of sorption-desorption cycles.
