“…[14,15] Comparable systems were reported by The Dow Chemical Company in the same period. [16] In particular, an important model system composed of bulk iron oxide promoted with titanium, zinc, and potassium oxide was developed for industrial applications. [17] These catalytic systems showed high selectivity towards lower olefins while exhibiting a low methane make (10%) and serve as the reference in bulk HTFTS catalyst development.…”

A series of Fe-Ti mixed oxide model catalysts containing different Ti/Fe ratios were synthesized and applied as catalysts for the High Temperature Fischer-Tropsch reaction (HTFTS). XRD, H 2-TPR and in situ Mössbauer and XAFS spectroscopy were applied to evaluate the role of Ti on the physical and chemical properties of Fe within the mixed metal oxide. It was observed that the Ti/Fe ratio determines the relative amounts of hematite, pseudobrookite, and anatase in the starting materials. The interplay between these phases is responsible for the HTFTS catalytic performance. Our results demonstrate that the presence of pseudobrookite: i) enhances the dispersion of iron; ii) mediates and controls the reduction and carburization degree during the transformation of Fe (III) species to carbides upon activation, and iii) increases the stability under HTFTS conditions by minimizing the re-oxidation of iron carbides. Highest catalytic activity and stability is achieved for the material with Ti/Fe ratio of 1/2.1.

“…In this journal, several papers have reported the heterogeneous catalytic process , and the catalytic reduction of NOx, bromates, and methyl oleate for undergraduate experiments. ,, Only a few CO/CO 2 conversion experiments have been presented for undergraduates despite the importance of this synthesis process in real-world applications. , Rubner et al described educational modules on the power-to-gas concept using Sabatier’s reaction (CO 2 methanation) as an example to show a path to renewable energy. This work only provides a science education curriculum for first-year undergraduate students or the general public.…”

Organizing undergraduates in chemistry, energy engineering, and chemical engineering specialties to participate in an energy transformation experiment can encourage them to think about the impact of human activities on nature and stimulate them to learn more about the topic. This laboratory experiment demonstrates a general approach to the methanation of syngas in a fixed bed reactor with online chromatographic monitoring. Undergraduates gain the opportunity to operate temperature controllers, mass flow meters, fixed bed reactors, gas chromatography, and cold traps as well as broaden their knowledge of renewable CO/CO 2 conversion. The experiment also offers a discussion about the chemical principles in catalytic conversion of syngas to methane, viable alternatives to green fuel sources, and the catalytic reaction process.
