The dispersion of Sr and K supported on limestone-eggshell-based CaO support and its effect in the canola oil transesterification were studied in this work by changing the Sr/(Sr + K) molar ratios in 0.2, 0.3, and 0.4, keeping the K loading in 9 wt%. K and Sr were impregnated with methanol at 60 °C...
