Effect of mixture of alcohols on biodiesel properties which produced from waste cooking oils and compare combustion performance and emissions of biodiesels with petrodiesel
Journal Title: Advances in Environmental Sciences - International Journal of the Bioflux Society - Year 2012, Vol 4, Issue 3
Abstract
Increasing the petroleum price and environmental problems have been driving forces to find alternative and renewable energy resources. Biodiesel has attracted the attention of many researchers due to various advantages associated with its usages. Several aspects including the type of catalyst, molar ratio of alcohol to oil, temperature, purity of reactants and free fatty acid content have mainly influence on transesterification. In this work, waste cooking oils and two types of alcohols with different molar ratio of methanol to ethanol and potassium hydroxide as catalyst were used as materials. Effect of alcohol on the physical properties, combustion efficiency and emitted gases of biodiesels were studied and compared with petrodiesel. Mixture of methanol and ethanol were used for transesterification in order to optimize solvent property of methanol and rapid equilibrium using methanol. Waste cooking oil is considered as the most suitable material due to its availability and cost-effectiveness. To examine the performance and emissions of biodiesels, a wet base semi-industrial boiler was used for combustion and a flue-gas analyzer has measured the emitted gases. Finally, physical properties of biodiesels were measured in Abadan’s Oil Refinery Laboratory
