HYDROCARBONS SYNTHESIS FROM A SIMULATED BIOSYNGAS FEED OVER FE/SIO2, CATALYSTS

The Fischer Tropsch reaction, using a simulated gas mixture similar to that obtained from biomass transformation (biosyngas), was studied over Fe/SiO2catalysts. The reaction was carried out in a stainless steel fixed bed reactor at 300 °C and 1 MPa. Excess solvent impregnation was used to prepare th...
