Highly Active Fischer-Tropsch Synthesis Fe-BDC MOF-Derived Catalyst Prepared by Modified Solvothermal Method

Abstract

Fe-MIL-88B was prepared by a method that utilizes ferric nitrate and terephthalic acid (TPA or H2BDC) as precursors. The catalyst was characterized by TEM, SEM, FTIR, XRD, BET, and TGA. The pyrolyzed MOF (Fe-MIL-88B/C) was then tested for FTS at 300 psi, 300/340°C and H2/CO=1 after reduction under flow of hydrogen at 400°C for 4 hours. GC product results show promising FTS performance and stability compared to previously reported Fe-MOF derived catalysts with CO conversion of 96.90% at 340°C for 40 hours and 97.45% at 300°C for 26 hours.
