摘要
A novel magnetic catalyst with hollow cylinder shape based on K2CO3/γ-Al2O3/Sepiolite/CoFe2O4 was prepared to convert macroalgae oil (Fucus vesiculosus) into biodiesel in an unconventional reactor assisted by magnetic field. Catalysts were formulated by the extrusion and characterized satisfactorily by physicochemical (mechanical strength, XRD, TG/DTG, FTIR and TPD-CO2), magnetic (VSM and EPR), morphological (SEM) and textural properties (BET). While their catalytic performance was also evaluated at 70 °C, oil: ethanol molar ratio 1:12 and 6 wt.% of catalyst using two different reaction systems for comparative purposes: (a) conventional stirred reactor and (b) fluidized bed reactor assisted by a magnetic field. The attained biodiesel presents properties in accordance with the standard limits (ASTM and EN) and total conversion (>99%) was observed in both cases after 2 h of reaction without significant differences between the two reactors. However, the magnetic properties of these catalysts allowed stabilization of the bed under a magnetic field and easy magnetic catalyst separation/recovery at the reaction end, showing their great potential for biodiesel production with regard to conventional process and thus, transforming it into a more sustainable technology.
