ABSTRACT
Because of its environmental advantages, biodegradability, and renewability, biodiesel has become a subject that is rapidly attracting global interest. As an alternative fuel for diesel engines, it is becoming increasingly important due to diminishing petroleum reserves and the environmental consequences of exhaust gases from petroleum-fuelled engines. Transesterification of a triglyceride feedstock with methanol or other short-chain alcohols is common for biodiesel processing. Analysis of transesterification of tiger nut oil is presented in this paper. The oil was extracted using the solvent process, yielding a percentage of oil yield of - 26.24 percent. The oil's physicochemical properties included density(0.84g/Cm³), moisture content(5.30),specific gravity-0.84, saponification value_157.37,acid value (3.336mgKOH/g),FFA(1.68),Peroxide value(5.01) and Iodine value(79.83gl/100g).The physicochemical parameters of the biodiesel were compared to the ASTM standard, and it was found that tiger nut oil is a good supplementary feedstock for biodiesel synthesis since the results are within the ASTM specification standard.
