Biofuel production over Fischer-Tropsch synthesis: effect of Fe-Co/meso-HZSM-5 catalyst weight on product composition and process conversion

Fischer-Tropsch Synthesis (FTS) using Fe-Co/meso-HZSM-5 catalyst has been investigated. The impregnated iron and cobalt on HZSM-5 could be used as bifunction which combined polimerizing synthesis gas long hydrocarbon cracking for making biofuel (saturated C5–C25 hydrocarbons gasoline, kerosene diesel oil). study emphasized the effect of weight product composition process conversion. HZSM-5, had converted from ammonium ZSM-5 through calcination, then desilicated with NaOH solution. Co(NO3)2.6H2O Fe(NO3)3.9H2O were precursor incipient wetness impregnation (IWI) amorphous meso-HZSM-5. consisted 10 % Fe 90 Co by weight, called 10Fe-90Co/meso-HZSM-5. All catalysts reduced in situ continuous reactor flowing hydrogen at 25 mL/min, 1 bar, 400 °C hours. performance was observed same fixed bed mL/min (30 CO, 60 H2, N2), 250 °C, 20 bar 96 Various (1, 1.2, 1.4, 1.6 gram) applied FTS. properties (BET analysis) 6.1–29.9 nm mesoporous diameter, 0.3496 cc/g average volume, 526.035 pore surface area, EDX analysis gave 22.1059 Si/Al ratio 16.11 loading (by weight) showed XRD spectra (66°), Fe-Co alloy (44.50°) Co3O4 (36.80°). reaction gram 10Fe-90Co/meso-HZSM-5 produced largest normal selectivity gasoline (19.15 %) (55.18 %). While oil (24.17 obtained 1.4 catalyst. CO conversion per similar value (CO 26–28 all
