Physical–chemical properties and thermal behavior of fodder radish crude oil and biodiesel

In this paper the characteristics of fodder radish, a potential biodiesel source, are investigated. Recent developments in fodder radish biodiesel production and studies on the composition of fodder chemical structure are reviewed. The physical–chemical characteristics of fodder radish crude oil and biodiesel were measured and compared with available literature data and biodiesel specifications. The measured properties were density, kinematic viscosity, carbon residue, sulfur content, acid number and iodine value. A thermogravimetric analysis to evaluate the thermal behavior of fodder radish crude oil and biodiesel is included. The results show that fodder radish biodiesel can meet physical–chemical property specifications, although its acid number requires attention.

► Fodder radish biodiesel meet density, viscosity and sulfur content specifications.
► Fodder radish biodiesel carbon residues and iodine value also attend specifications.
► Fodder radish biodiesel thermogravimetry indicates favorable engine performance.
