Effect of boron source on the catalyst reducibility and Fischer–Tropsch synthesis activity of Co/TiO2 catalysts

Impact of Boron Modification on MCM-41-Supported Cobalt Catalysts for Hydrogenation of Carbon Monoxide

“…Li et al [26] also reported that the addition of boron (0.05 wt.%) onto Co/TiO 2 did not change the activity of the catalyst at lower space times and slightly increased the conversion at higher space times. The result [25] was in agreement with what we have found here regardless of the supports used. Thus, B modification consistently caused a decrease in reducibility of Co catalysts due to strong support interaction.…”

“…It seemed that the impact of B modification on the MCM-41 supports was more pronounced indicating the shift of reduction temperature to higher values. In fact, the effect of B source on the catalyst reducibility and Fischer-Tropsch synthesis activity of Co/ TiO 2 catalysts was investigated by Coville et al [25]. They reported that for all series of catalysts, at low B loadings (B wt.% < 0.05), reaction rates increased with increasing B loading; at high B loadings (B wt.% > 0.1%), there was a decrease in reaction rate.…”

Fischer–Tropsch Synthesis on Lanthanum Promoted Co/TiO2 Catalysts

“…Recent years, titania-supported cobalt catalysts have been extensively investigated [3][4][5][6][7][8][9][10]. The Co/TiO 2 catalyst has strong metal support interaction (SMSI) which significantly affects the cobalt dispersion and reduction of the catalyst.…”

Effect of TiO2 crystallite size on the dispersion of Co on nanocrystalline TiO2

“…In addition, as a catalyst support particularly in hydrogenation reactions, TiO 2 manifests a strong metal-support interaction (SMSI) with group VIII metals resulting in an improved catalytic performance [4][5]. It has been reported that Co/TiO 2 shows high activities in CO hydrogenation and gives a distribution of Fischer-Tropsch products ranging from C 1 to C 18+ hydrocarbons with high selectivity for C 2 -C 11 [6].…”
