Catalysts Derived from Waste Sources in the Production of Biodiesel Using Waste Cooking Oil
Catalysts fully derived from waste materials in order to make sustainable chemical reactions have been a recent topic of interest. Calcined (900 ◦C, 2 h) calcium oxide (CaO) sourced from waste mud crab shells and cockleshells were mixed in a 1:1 mass ratio to be used for transesterification of wast...

| description | Catalysts fully derived from waste materials in order to make sustainable chemical reactions have been a recent topic of interest. Calcined (900 ◦C, 2 h) calcium oxide (CaO) sourced from waste mud crab shells and cockleshells were mixed in a 1:1 mass ratio to be used for transesterification of waste cooking oil (WCO) at 5 wt.% catalyst and a methanol to oil molar ratio of 13:1 for 3 h at methanol refluxing temperature to give 98% conversion. Then, boiler ash (BA) from agricultural waste was used to transesterify WCO at 3 wt.% catalyst and a methanol to oil molar ratio of 15:1 for 0.5 h at methanol refluxing temperature to give 89% conversion. In order to reduce the reaction time (for CaO-catalyzed reaction) and to increase the conversion (for BA-catalyzed reaction) various amounts of BA were added to 5 wt.% of mixed CaO and optimized using Central Composite Design (CCD). The optimized conditions predicted by CCD were found to be 3.39 wt.% boiler ash, with a reaction time of 32.3 min and a conversion of 99.5%. The predicted results agree with the experimental results (3 wt.% boiler ash, reaction time of 30 min with 99% conversion). |
