Waste beef tallow

The factors that affect transesterification such as temperature, time and molar ratio have been included. The study reveals that waste beef fat would be a suitable replacement of vegetable oils due to low cost, its role in protecting the environment, and beef tallow esters are close to ASTM D 6751 biodiesel standards. Research work needs to be carried out on heterogeneous catalysts and low-cost lipase catalysts to improve productivity.

The physical properties of beef tallow i.e. methyl esters density, kinematic viscosity, cloud point, pour point, cold filter plugging point (CFPP), acid value, calorific value, and flash point, were within ASTM standards for biodiesel.

This research utilized low cost feedstock of waste beef tallow for biodiesel synthesis and its application in a CI engine. The biodiesel and diesel blends B0, B20, B40, B60, B80 and B100 were used in a stationary tractor diesel engine. Performance and emission parameters brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), exhaust gas temperature (EGT), carbon monoxide (CO), oxides of nitrogen (NOx) and hydrocarbon (HC) were tested at a constant speed of 2000 rpm and varying loads.
