Effect of Catalyst on Transesterification of Waste Vegetable Oils from Food Processing Facility
Converting waste vegetable oils from food processing facilities, restaurants and households to biodiesel by the transesterifi cation reaction with methanol has important advantages for human health and environment. Th e transesterifi cation reaction of waste vegetable oils is aff ected by free fatty acids and water content of oils and fats, type of alcohol, type and quantities of catalyst, reaction temperature and reaction time. Basic aim of this paper is to explore eff ect of type and quantities of catalyst on transesterifi cation process of diff erent waste vegetable oils from food processing facilities with methanol. Comparison of basic characteristics between produced biodiesel, industrially produced biodiesel and values from European standards for biodiesel fuel (EN14214) was made.
