Construction and Operation of a Fischer-Tropsch Laboratory System with a Liquid Phase Reactor

摘要

Among the products of the Fischer-Tropsch reactions, the olefins in the range C2 to C4 are important raw materials for the chemical industry. This report describes an effort to use new catalysts and to vary the reaction conditions so as to increase the yield of C2/C4 olefins. The reaction took place in liquid phase reactors of various size and in small fixed-bed reactors. The melt catalysts of Sasol Company and the precipitation catalysts of Ruhrchemie company, as well as iron whisker catalysts were tested. By means of the new catalysts, yields of C2/C4 olefins could be increased from a previous value of less than 40 g to more than 60 g per cu m (V(n) hydrogen and carbon monoxide.
