Biodiesel is a monoalkyl esters of long chain fatty acids derived from renewable feedstock like vegetable oils and animal fats. It is produced by transesterification in which oil or fat is reacted with a monohydric alcohol in the presence of a catalyst. In this research, transesterification process was used to convert olive oil and cashew nut oil into biodiesel (methyl ester). The selected material used in the preparation of this biodiesel was methanol, alkaline catalyst (KOH), constant temperature of 70o C at 1.5hrs, to optimize the experimental conditions for maximum biodiesel yield. The thermodynamic properties of the biodiesel produced such as heat content of the pure biodiesel (B100) and the blends were investigated.
