? 2022 Elsevier B.V.Highly stable catalysts were prepared by wet impregnation of blast furnace dust (BFD) in Na2CO3·H2O, Na2CO3·10H2O, NaHCO3 and Na2CrO4 solution and subsequent calcination at 300–600 °C. At low temperature of 65 °C for 2 h with methanol/oil molar ratio of 15/1, high biodiesel yield of 100 wt% was obtained with for both Na2CO3·H2O@BFD300 and Na2CO3·H2O@BFD400 catalyst (impregnating with Na2CO3·H2O solution and calcining at 300 and 400 °C) at 7 wt% for the first use. Na2CO3·H2O@BFD300 catalyst exhibited outstanding stability and recyclability with biodiesel yield of 100 wt% at the fifth use (93 wt% at the twelfth use) owing to the formation of stable and active nanocomponents of NaFeO2 (32.42 nm) and magnetic nanocomponent of Fe3O4 (size of 3.14 nm and magnetization of 6.16 Am2/kg). This study finds a solution to use solid waste for the green production of biodiesel.
