The use of silver modified stationary phases for the separation of olefins from hydrocarbon mixtures was investigated. Gas solid chromatography (GSC) was found to be a quick and efficient technique for screening ion exchange resins and zeolites as potential support materials in olefin separation. Using GSC, the efficiency of Ag⁺ exchanged resin in retaining olefins relative to alkanes in a given mixture was found to be dependent on the porosity of the resin used. The silver form of the porous, macroreticular type Amberlyst A-15 resin strongly retained olefins in the GC column as compared to the microporous Amberlite IR(120) resin. Olefins were so strongly retained on the Ag⁺exchanged Amberlyst A-15 resin that they could only be eluted efficiently from the GC column at elevated temperatures. The Ag⁺ exchanged resin was however found to undergo degradation at elevated temperatures (> 140⁰C) and hence the resin packed columns could not be re-used. 2016-03-28T14:45:07Z 2016-03-28T14:45:07Z 1994 Master Thesis Masters MSc http://hdl.handle.net/11427/18345 eng application/pdf Department of Physics Faculty of Science University of Cape Town |
