Abstract
An adsorptive process to separate the components of a solution of linear and branched hydrocarbons into a linear hydrocarbon portion and a branched hydrocarbon portion where the adsorbent is an aryl-bridged polysilsesquioxane has been developed. The hydrocarbon components to be separated may be alkanes, alkenes, or alkynes, and the aryl-bridging group of the adsorbent may be phenylene, diphenylene, terphenylene or anthrylene. A specific embodiment of the invention is one where the process is operated in the simulated moving bed mode.
