Abstract

Sodium metasilicate (SMS) tended to agglomerate during glycerolysis reactions in high shear compartment reactors (HSCR), hindering triacylglycerol (TAG) conversion. Therefore, the aim was to evaluate the SMS-magnesium oxide (MgO) blend as a heterogeneous catalyst for glycerolysis reactions. Various SMS-MgO ratios (ranging from 2.5:1 to 10.0:1) were evaluated. The results demonstrated that increasing MgO in the blend reduced catalyst basicity and minimized O-Si-O groups and catalyst crystallinity, preventing clumping and increasing catalyst surface area. The SMS-MgO 5.0:1 blend exhibited the smallest pore size (<2 nm) with a surface area of 4.22 m2 . g–1 and basicity of 11.59 ± 0.115 mmol . g–1. This blend achieved the highest TAG conversion of 53.98%, with a MAG content of 16.86 ± 0.528% when it was performed at 120 °C with an agitator speed of 2,000 rpm for 6 h. Thus, the SMS-MgO 5.0:1 blend shows promise as a heterogeneous catalyst in glycerolysis reaction in HSCR, hindering agglomeration and enhancing surface area.
