Synthesis of Ethyl Esters from Waste Cooking Oil Using a Calcined Coconut Husk-Based Catalyst: A Novel Green Approach
A low-cost heterogeneous base catalyst was prepared by simple calcination of coconut husk at 700°C and applied to the ethanolysis of Waste Cooking Oil (WCO). The catalyst was characterised by FTIR, XRD, SEM and nitrogen physisorption, revealing a silica-rich matrix containing crystalline quartz,…...
