1. 1. Supercritical Hydrogenation of Vegetable Oils

   Författare :Maj-Britt Macher; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium catalyst; supercritical; hydrogenation; silver ion HPLC; rapeseed oil; fatty acid methyl ester; trans fatty acid; palm oil; deactivation; propane;

   Sammanfattning : Vegetable oils were hydrogenated in a supercritical single-phase mixture with propane and hydrogen. The reaction was carried out in a small (0.5 ml) fixed-bed reactor and the influence of different process parameters was investigated. LÄS MER

3. 2. Coke on Supported Palladium and Platinum Catalysts

   Författare :Mikael Larsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TPO; palladium; deactivation; coke; propane dehydrogenation; microbalance; vegetable oil hydrogenation; acetylene hydrogenation; catalysis; platinum;

   Sammanfattning : Catalyst deactivation by coke formation has been investigated in three heterogeneous catalytic processes, propane dehydrogenation, acetylene hydrogenation and hydrogenation of vegetable oil. Palladium and/or platinum supported on alumina were used as catalysts in all reactions. LÄS MER
