Abstract
The article presents experimental data on testing synthetic CaA-type zeolite for the purification of isopentane fractions from impurities of normal pentane. The separation of hydrocarbon mixtures the components of which are close in physicochemical constants is of particular difficulty in the technological processes of petrochemical production, while conventional methods cannot provide the required degree of separation, which is also characteristic of pentane isomers. It is shown that for the separation of substances, based on the difference in the size and shape of the molecules, a domestic CaA-type zeolite can be successfully used. Research methods and conditions of paraffin hydrocarbon sorption-desorption on a laboratory flow-through unit are described. It has been found that the adsorption capacity of zeolite under the experimental conditions is 11,8 g of n-pentane per 100 g of zeolite, with a purity of the purified fraction not lower than 99 %. Based on the results obtained, optimal conditions for the process of isopentane fraction purification have been selected.
