FISCHER-TROPSCH SYNTHESIS OF HYDROCARBONS IN THE GASOIL RANGE
Preparation of liquid fuels from coal is one of the major routes to make the European economy more independent of petroleum. The well-known Fischer-Tropsch synthesis (which transforms CO + H-2 into hydrocarbons, alcohols and olefins) has demonstrated its technical feasibility. The major disadvantage is the lack of selectivity to obtain higher yields of gasoline and/or diesel, which is inherent to the chemical mechanism (a polymerization scheme according to Schulz-Flory kinetics) with the type of catalysts presently used. To be applicable in European economic conditions, Schulz-Flory kinetics will have to be circumvented to improve selectivity. This requires the development of new catalysts and the optimisation of their use. This work involves the development and optimisation of catalysts for the high selectivity preparation of hydrocarbons, olefins and alcohols from coal. With these catalysts it should be possible to synthesize motor fuels in a direct process which will not require major refinery operations after synthesis. For this purpose, a batch reactor and a continuous reactor with a gas chromatograph have been installed. The active metal of the catalyst is either ruthenium or cobalt. The supports used are kieselguhr and microporous alumina. The catalysts were calcinated in air and then reduced under hydrogen in the reactor (so that they become active).
