Abstract
Authors report a novel Raney Fe@HZSM-5 Fischer–Tropsch synthesis catalyst which was synthesized using a one-pot strategy employing an FeAl alloy as the Fe precursor and as the Al source.
Besides cracking/isomerization of heavy hydrocarbons, HZSM-5 also stabilizes Hägg carbide, resulting in excellent selectivity to gasoline fraction and unexpectedly enhanced C₅₊ selectivity.
