Effects of Thermal, Physical, and Chemical Properties of Biodiesel and Diesel Blends

Abstract

The biodiesels are the fuels composed of mono-alkyl esters of long chain fatty acids derived from the renewable energy sources, such as vegetable oil, animal fat, etc. The thermogravimetric analysis (TGA) from thermal, density and viscosity from physical and iodine value from the chemical properties has been considered for the study, by considering this objective the literature review was done through the research papers of last two decades. The conclusions drawn are as follows, the thermal property TGA is an important property which shows the distillation and decomposition, and it provides behavioural information of a substance are measured as a function of temperature. The density and viscosity from the physical properties for different biodiesel strongly affect the fuel consumptions of engine system and it has been seen that density and viscosity strongly dependent on the temperature. The iodine value from chemical properties, the iodine value for different biodiesel and diesel blends increases as the biodiesel fractions increases in the blends.
