ABSTRACT:
A process to separate at least two classes of hydrocarbons of a solution using an alkylene-bridged polysilsesquioxane adsorbent has been developed. The classes of hydrocarbons to be separated may be saturated hydrocarbons, unsaturated aliphatic hydrocarbons and aromatic hydrocarbons. The alkylene-bridging group may contain from about 2 to about 14 carbon atoms. A specific embodiment of the invention is one where the components of a solution of aromatic, unsaturated aliphatic, and saturated hydrocarbons are separated into an aromatic hydrocarbon portion, an unsaturated aliphatic hydrocarbon portion, and a saturated hydrocarbon portion where the adsorbent is an alkylene-bridged polysilsesquioxane.
