ABSTRACT:

The formation of short-chain hydrocarbons on a sintered iron/manganese catalyst is investigated in this work. This sintered catalyst, contrary to a precipitation catalyst exhibits the same chemical composition, a higher selectivity of short-chain olefins. The Fischer-Tropsch synthesis takes place in a temperature range of 255 to 333 exp 0 C and at pressures of up to 20 bar. The part system ethylene/ethane was closely examined by adding ethylene. It was shown that paraffins and olefins probably have the same precursor which yields olefins by eliminating hydrogen and by hydrogenation to form paraffins. The evaluation of measured results (conversion considering the kinetic parameters) gives a formal kinetic description of the reaction rates which can be transferred to a large scale reactor and desired product optimization.
