Methyl Ester Production from Waste Frying Oil

Abstract

Uaed adible plants oil or animal fat have a potential to use as alternative and renewable sources of diesel fuel. The research objective is 1) to perform ratio of waste frying oil (WFO) and methanol 2) to wash and clean methyl ester and 3) to test of fuel property. The WFO was esterified with methanol in the presence of NaOH catalyst, at 55-60 ℃ with 1000 r/min stirring for 60 min. The working ratio WFO and methanol was established, It was found that 5:1 by volume results in 96 % of yield. Washing and cleaning methyl ester by step using water and NaCI solution to give cleaned products. The fuel properties were tested and found that decreasing of viscosity 6.24 cSt, flammable, net capacity of heat 39,519 J/g. Machine test for number of starting was 2-5 times and fuel consumption was averaging 3.1 hour/liter. The environment concerns more friendly than petroleum diesel due to low black smoke and less carbon particulated. It can concluded that biodiesel from WFO has a potential use as alternative diesel fuel and is better for the environment.
