Abstract

Waste cooking oil from restaurants and hotels is expected to be thrown away. As a result, waste cooking oils (WCO) which have no pre-treatment will unfavourably pollute the earth. One of the approaches to treat and use the waste cooking oil is by its conversion into biodiesel. This paper illustrates the study on the active reaction of waste cooking oil transesterification into biodiesel and identifies the best set of input parameters for the most economical yield of biodiesel. The sample of WCO for the present study was collected from the restaurants. Methanol was used as a reactant along with two homogeneous base catalysts(KOH, NaOH) and one heterogeneous base catalyst(CaO). The input parameters selected for the study were methanol-to-oil molar ratio, catalyst type, reaction temperature and reaction time. The orthogonal experimental array L9 was selected for the present study with four parameters and three levels. The optimum set of input parameters for the transesterification process is; 8:1 methanol-to-oil molar ratio, KOH as a catalyst, 55 °C reaction temperature and 120 min of reaction time. The optimum yield of FAME was 92.5% with 1.0% catalyst concentration by weight.
