Glycerol is a by-product of the biodiesel manufacturing process, glycerol is obtained by reacting triglycerides with alcohol. The raw materials used are used cooking oil and methanol. The purpose of this research To determine the effect of Recydu Catalytic Cracking catalyst on glycerol conversion. In this study to obtain the conversion of glycerol, namely through 2 reaction processes, namely the esterification reaction and the trans-esterification reaction,by using 4 variables, namely Stirring Speed and Reaction Comparison and Stirring Time and Amount of Catalyst. The glycerol conversion was obtained from the analysis data for the determination of the total fatty acid equivalent and the analysis of the acetin method. From the results of the study, it was found that the variation of stirring time on the amount of RCC catalyst obtained the largest conversion, namely 52.3% at optimum conditions at 105 minutes and the amount of catalyst was 2.1 grams. Meanwhile, in the variation of Stirring Speed and Reaction Comparison, the largest conversion was obtained, namely 54.51% at the optimum condition at a reaction ratio of 1:3 and the optimum condition at a speed of 90 rpm.
