Batch and fixed bed column selective adsorption of C-6, C-8 and C-10 linear alpha-olefins from binary liquid olefin/paraffin mixtures onto 5A and 13X microporous molecular sieves

摘要

The separation of gaseous olefin/paraffin mixtures by physical adsorption and pi-complexation chemical adsorption has been widely investigated, while studies on the adsorption of liquid olefin/paraffin are much rarer. One of the most important reasons is that it is difficult to determine the actual adsorption capacity of liquid phase adsorption directly through experiments, and the study of liquid olefin/paraffin mixtures adsorption capacities has not been sufficiently systematic. In this paper, the adsorption of C-6, C-8 and C-10 linear alpha-olefins onto 5A and 13X molecular sieves from binary liquid olefin/paraffin mixtures in batch and fixed bed column systems was systematically investigated.
