Aim of The Work The present work aims to study the factors affecting biodiesel production (i.e. temperature, catalyst loading % wt, time and agitation speed) from low FFA content waste vegetable oil and it introduces an optimization of these factors to obtain the maximum oil conversion. 4/4/2016 Eslam G.

Experimental Work Methodology Experimental Procedure Results and Discussion 4/4/2016 Eslam G. Al-Sakkari

Methodology The methodology followed in this part is to perform set of experiments in which only one factor is changed and the rest are fixed at certain values. Then at the highest conversion observed, this point is considered to be the optimum one for changing factor. Then another factor is chosen and the previous steps are applied again till all optimum values of different factors are obtained. 4/4/2016 Eslam G. Al-Sakkari
