Title
Effect of potassium addition on the product selectivity of Ru:Mn/alumina supported catalyst system for Fischer–Tropsch reaction
Abstract

The catalytic behavior of a series of Ru/Al2O3 catalysts promoted with various levels of Mn and K prepared by co-impregnation method were investigated in the CO hydrogenation reaction. Catalytic studies showed that the addition of Mn enhances the production of Fischer–Tropsch products and K promotion in particular enhances the production of unsaturated hydrocarbons while inhibiting the methanation reaction. The influence of K and Mn on the Fischer–Tropsch product selectivity in CO hydrogenation studies is discussed in terms of ensemble and electronic effect; and the production of new surface site Ru:Mn:K in accordance with our characterization results.
