Alpha-olefin selectivity during conventional and supercritical Fischer-Tropsch synthesis Academic Article uri icon


  • Fischer-Tropsch synthesis was studied on a precipitated iron catalyst (Ruhrchemie LP 33/81) in a fixed bed reactor at several different temperatures (235C, 250C and 265C) and synthesis gas feed compositions (H2/CO = 0.67, 1 or 2) under both supercritical (propane as a supercritical fluid) and conventional (P = 1.5 MPa) operating conditions. It was found that the supercritical operation results in enhanced selectivity of -olefins relative to conventional (normal) operation. Both total olefin content and -olefin selectivity decreased with either increase in conversion or H2/CO molar feed ratio, whereas olefin selectivities were essentially independent of reaction temperature.
