Fischer-Tropsch synthesis Over titaniasupported cobalt catalyst : optimum pressure for C5+ hydrocarbons production

Abstract: Fischer-Tropsch (FT) runs were performed using a titania-supported cobalt catalyst at total operating pressures of 1, 10 and 20 bar respectively, to determine the optimal pressure for C5+ hydrocarbons production. The reaction temperature and feed flowrates were kept constant as 220oC and 20 Nml/gCat/min respectively. Lower methane and higher C5+ hydrocarbons selectivities were measured at higher pressure. However the highest rate of C5+ hydrocarbons production was measured at an optimum pressure of 10 bar
