A cobalt catalyst (25%Co/γ-Al2O3, prepared by slurry phase impregnation) was used in a fixed bed reactor under a pressure/density tuned supercritical fluid mixture of n-pentane/nhexane. By using an inert gas as a balancing gas to maintain a constant pressure, the density of the supercritical fluid could be tuned near the supercritical point while maintaining constant space velocity within the r...

Fe/Zn oxides promoted with K and Cu selectively produce a-olefins at typical FischerTropsch synthesis conditions (2/1 H2/CO, 1 MPa, and 270°C). The simultaneous presence of K and Cu introduces a synergistic activity enhancement while maintaining the high oletrm selectivity obtained by alkali promotion. Structural and morphological differences in Fe-Zn oxides prepared from ammonium glycolate com...

Abstract The effect of phosphorus on a cobalt-based catalyst for Fischer-Tropsch Synthesis (FTS) has been investigated. Phosphorus is an impurity present in biomass and, this work, its deposition the during to liquid (BTL) operation, based gasification and FTS, mimicked. For purpose, four different cobalt-manganese-rhenium catalysts supported alumina were prepared by incipient wetness impregnat...
