BIODIESEL PRODUCTION FROM GROUNDNUT OIL USING CALCIUM OXIDE AND MAGNESIUM OXIDE SUPPORTED OVER WOOD ASH AS CATALYST
Abstract
The increasing demand for sustainable and renewable energy sources has driven interest in biodiesel production from vegetable oils. This study explores the production of biodiesel from groundnut oil using calcium oxide (CaO) and magnesium oxide (MgO) supported on wood ash as a heterogeneous catalyst. The transesterification process was carried out under controlled conditions, optimizing parameters such as temperature, reaction time, catalyst concentration, and methanol-to-oil ratio. The results showed that the composite catalyst significantly enhanced biodiesel yield compared to conventional catalysts. The biodiesel produced met standard fuel properties, indicating its suitability as an alternative fuel. The use of wood ash as a catalyst support provides an environmentally friendly and cost-effective approach to biodiesel production.
