DOIAbstract
The effect of support and promoters on the catalytic properties of Fe supported in the FTS was studied. Precursors of supported Fe on SiO2 and SBA −15 were synthesized and doped with Cu and K. The precursors were activated in pure H2 and catalytically tested with a mixture of H2:CO = 2:1, T = 543 K and P = 10 bar. The samples were characterized by atomic absorption, N2 adsorption, X-ray diffraction, TEM and TPR. Also, we used the DFT to study the changes of the electronic structure when the Fe, K and Cu are adsorbed on the SBA-15 surface. The incorporation of different ions do not alter the structural and textural properties of the support. In the FTS, all the catalysts supported on SBA-15 presented a low selectivity towards methane and a p...
