Fischer Tropsch Synthesis using promoted cobalt-based catalysts

•Addition of P to a CoMnOx catalyst decreases CH4 and CO2 formation.•Addition of La to a CoMnOx catalyst decreases CH4 and CO2 formation.•Combined addition of La and P decrease CH4 and CO2 further.

A series of CoMnOx catalysts with lanthanum and phosphorus promoters were prepared by wet impregnation and investigated for syngas conversion to hydrocarbons activity via Fischer Tropsch Synthesis. The effects of the promoters on the catalyst structure were examined by ICP, XRD, TPR and XPS measurements. The results of the catalytic tests showed that the addition of promoters altered the product selectivities when compared to the unpromoted catalyst.
