Supercritical phase Fischer–Tropsch synthesis over cobalt catalyst

摘要: Abstract A supercritical phase Fischer–Tropsch reaction over a SiO 2 supported cobalt catalyst in fixed bed reactor was studied this paper. Four different fluids: n -pentane, -hexane, -heptane and -decane were investigated. Similar CO conversion, hydrocarbon distribution, 1-olefin content of the products, etc. obtained -hexane -heptane; however, products obviously lower than that -heptane. Under conditions used study, conversion increased with increasing temperature decreasing W/F (CO+H ) . The partial pressure had little influence on under total syngas kept constant. In general, change distribution not obvious operating (time-on-stream, temperature, , etc.). remarkably performances synthesis (FTS) also compared those fluidized gas bed. results show higher but slightly
