ABSTRACT:
Disclosed is a method and an apparatus for analyzing the composition of a gasoline-range petroleum product using a new copper on silica gel adsorption composition. The copper on silica gel adsorption composition is capable of separating olefins from saturates in a mixture by temporarily retaining the olefins while allowing the saturates to pass through. The method of analysis entails passing a gasoline sample through an absorption column whereby the aromatics are retarded while the saturates and olefins pass through. The saturates and olefins are then directed through the copper on silica gel composition wherein the olefins are retained while the saturates pass through into a detector and are measured. Once all the saturates are removed from the system, the aromatics are backflushed from the absorption column and are routed into the detector for measurement. Lastly, the copper on silica gel composition is elevated in temperature so as to release the olefins which then likewise pass into the detector for measurement. The flow of the various streams is facilitated by a compatible carrier gas, such as nitrogen.
