Effect of K promotion of Fe and FeMn Fischer–Tropsch synthesis catalysts: A…
Abstract. Promoting a precipitated FeCuSiO2 catalyst with Mn has been shown to significantly improve its catalytic activity for Fischer–Tropsch synthesis (FTS). Although the impact of K promotion on the activity of Fe catalysts with and without Mn addition has been studied previously, no one has previously delineated how K influences the concentration of active surface intermediates and t…

Impact of Cr, Mn and Zr addition on Fe Fischer–Tropsch synthesis catalysis:…
Abstract. Recently, we reported that Cr, Mn, or Zr promotion of a precipitated Cu-promoted Fe Fischer–Tropsch synthesis (FTS) catalyst significantly improves its catalytic activity. In this study, we used steady-state isotopic transient kinetic analysis (SSITKA) of methanation to investigate the activity of these catalysts at the site level, providing insight into how this promotion enhan…

Esterification and transesterification using modified-zirconia catalysts
Abstract In this paper, modified zirconias (WZ, SZ, and TiZ) have been extensively compared under the same reaction conditions as catalysts for both the transesterification of triglycerides (TGs) and the esterification of carboxylic acids (free fatty acids, FFAs) with ethanol. In addition, for the first time, the catalyzed rate of hydrolysis/esterification + transesterification of triglyceride…
