ABSTRACT:
A process to separate at least two classes of hydrocarbons of a solution using an aryl-bridged polysilsesquioxane adsorbent has been developed. The classes of hydrocarbons to be separated may be saturated hydrocarbons, unsaturated aliphatic hydrocarbons and aromatic hydrocarbons. The aryl-bridging group may be phenylene, diphenylene, terphenylene, or anthrylene. 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 aryl-bridged polysilsesquioxane.
