Fischer-Tropsch-Synthese. Neuere Untersuchungen und Entwicklungen

Fischer-Tropsch synthesis – Recent studies and Developments . This article surveys some results of recent research and new lines of development in Fischer-Tropsch synthesis. Most interest is focussed on variants synthesis showing high selectivity of C₂-C₄ alkenes or C₅-C₂₀ 1-alkenes or Diesel oil. In the last decade catalysts of improved alkene selectivity have been developed. Also the dependence of selectivity on process parameters such as pressure of hydrogen and carbon monoxide and temperature has been investigated in order to find appropriate conditions of operation for a synthesis of high selectivity. Some preliminary process designs are discussed.
