The synthesis behaviour of the manganese-iron catalyst, developed by Koelbel and Tillmetz, for the selective guidance of the Fischer-Tropsch synthesis to produce short-chained olefins was stabilized using a stochastic optimization process. In the liquid phase synthesis, yields of 50-65g C sub 2 -C sub 4 olefins could be obtained per normal cubic meter of converted syngas. The product distribution corresponds to the Schulz-Flory distribution and can only be slightly influenced by technical measures applied to the reaction. The conversion of synthesis gas using mixed catalysts consisting of manganese-iron catalyst and the H-ZSM zeolite leads to hydrocarbon mixtures rich in aromatics and isomers. Based on these results, data for the direct, single-stage liquid phase synthesis of antiknock fuel were worked out. Simulations were carried out using a model and with these calculations the effect of operating parameters on the conversion and reaction performance in commercial suspension reactors can be determined. A new process variant of the Fischer-Tropsch liquid phase synthesis was developed for the direct conversion of syngas containing a very high proportion of carbon monoxide. (ERA citation 11:007062)
