Abstract

The search for sustainable and environmentally sound alternative for diesel are permanent and biodiesel has been proven to be a viable alternative. Biodiesel is a form of diesel fuel that is sourced and produced from animal fats or plant oils. Numerous plant oils such as palm oil and waste cooking oil have been utilized as feedstock to produce biodiesel. Other than feedstocks, there are also different ways to produce biodiesel, which could affect the yield and quality of the product. The purpose of this project is to produce biodiesel by mixing WCO and another raw material such as palm oil by using two different processes. The two types of processes applied in this study are one step process and three-steps process. One step process includes transesterification, while three-steps process includes pre-treatment, esterification, and transesterification. The quality of the biodiesels produced from the two process differs from one another, hence the biodiesels analyzed by using FTIR. The FTIR process determines the fatty acids that are present in the produced biodiesels. Not only that, but the optimum conditions of factors that influence the production of biodiesel are also optimized. There are several factors that affects the yield of biodiesel, such as methanol to oil ratio, amount of H2SO4 and KOH catalyst and palm oil to WCO ratio. Three of the most influential factors were chosen through preliminary lab test and heatmap correlation. The factors were further optimized by using RSM. The sustainability of utilizing WCO to produce biodiesel is also discussed.
