RESUMO

The Fischer-Tropsch synthesis reaction has received great attention due to its scientific and technological interest. This interest arises mostly in association with the dwindling of petroleum reserves, and because the Fischer - Tropsch synthesis offers an appropriate route for the transformation of solid fuels into liquid or gaseous fuels, as well as basic chemicals for the petrochemical industry. Considering the structure of the Brazilian market, this interest is essencially directed for the substitution of diesel and fuel oil. Accumulated experience with the synthesis reaction shows that it is possible to alter, within certain limits, the distribution of the products obtained. In this work a discussion is presented on the nature of the catalysts used in the Fischer - Tropsch synthesis, as well as on the reaction mechanism, with emphasis on catalysts based on iron. The aim of this discussion is to establish possible schemes for the development of optimized catalysts, with better activity and selectivity for desired product fractions(gasoline, diesel, olefins,etc). It is also presented the description of an experimental equipment developed for collecting kinetic data on the Fischer - Tropsch synthesis, and discussed the difficulties that were met in the preliminary tests, particularly with reference to chemical analysis of the products of reaction
