Abstract

In this paper, three nanocatalysts of iron, copper, and strontium were prepared by a microemulsion method. The composition of the final catalysts, in terms of the atomic ratios, are Fe, 100 Fe/3 Cu, 100 Fe/3 Cu/2 Sr. XRD, BET, TEM, and TPR techniques were utilized for the investigation of the phase, structure, and morphology properties of the synthesized catalysts. The performances of the catalysts were tested in a fixed-bed stainless steel reactor. Nanoiron catalyst contained promoter material improved the Fischer-Tropsch synthesis (FTS) and water-gas shift (WGS) activities, while decreased methane selectivity to 7.44%; CO conversion and chain growth probability were also increased to 63.3% and 0.66 respectively.
