“…of CO conversion to hydrocarbons. In a recent work by Surisetty et al on MoS 2 catalysts [9], it was suggested that activity is also influenced as the increase of K loading was found to increase Mo dispersion and the number of active sites in MoS 2 domains. In addition, alkali promotion seems to be essential for achieving high catalyst stability [10].…”

“…In attempts to improve these catalysts, many reports describe alkali-promoted molybdenum sulfide phases on high surface area supports, including alumina, silica, carbon nanotubes, activated carbon, and clay [3,[20][21][22][23][24][25][26][27][28][29]. In some cases higher alcohol productivity per gram of Mo was slightly improved while in others, higher alcohol selectivity was improved.…”

A Mg/Al mixed metal oxide material (MMO) is introduced as a support for K 2 CO 3 promoted MoS 2 in CO hydrogenation reactions at 310°C and 1,500 psig. The catalyst is shown to be more selective for C 2 -C 4 linear alcohols (substantially so for C 3 -C 4 linear alcohols) than for methanol and offers good alcohol to hydrocarbon selectivity. Methanol selectivity of the MMO supported catalyst deviates greatly from the Anderson-Shultz-Flory distribution.

“…Catalysts supported on CNF have been used in fuel cell applications [16], chemical synthesis such as hydrogenation [17], higher alcohol synthesis [18] and Fischer-Tropsch reactions [19]. Some examples that show the potential of these materials in hydroprocessing reactions of both model compounds and real feeds can be found in the literature.…”

Catalysts based on functionalised carbon nanofibers (FCNF) coated with Ni-decorated MoS 2 nanosheets were obtained by direct decomposition of ammonium thiomolybdate and nickel nitrate impregnated on the FCNF under controlled temperature conditions in inert atmosphere. The catalysts were characterised by X-ray Diffraction (XRD), N 2 adsorption, Raman spectroscopy, temperature programmed reduction of sulfur species (TPR-S), NH 3 temperature programmed desorption (NH 3 -TPD) and transmission electron microscopy (TEM). Decomposition temperature was found to have a paramount importance in the formation of uniform MoS 2 slabs, as revealed by the TEM study: at 600 °C, non-uniform covering of the carbon nanofiber (CNF) was observed Higher asphaltene conversions were obtained for the CNF-supported catalysts prepared at 450 °C, which overperformed the Al 2 O 3 -supported benchmark catalyst. However, the catalytic performance in hydrodesulfurisation and hydrodemetallisation of the CNFbased catalysts was slightly lower than that of the benchmark catalyst.
