In chicken fat, due to high polyunsaturated fatty acid content, the corresponding methyl esters display poor oxidative stability, as evidenced by an OSI value of 3.5 h at 110 °C. Removal of sulfur contents is also a serious issue. Copyright © 2010-2020 by Global Digital Central. 90(2011)1884–1891.

Calorimetry experiments that measure the heat of combustion can be performed at constant volume using a device called a bomb calorimeter.
Thus, the heat capacity is (6-4) A similar relation is used to determine the heat of combustion. Rama Raju Baadhe, ... Vijai K. Gupta, in Bioenergy Research: Advances and Applications, 2014. The biodiesel were made 0000159078 00000 n The heat that, is released warms the water surrounding the chamber.

0000003362 00000 n 0000002814 00000 n However, the availability of feedstock for producing biodiesel depends on the regional climate, geographical location, local soil conditions, and agricultural practices of any country. The quantity known as lower heating value (LHV) (or net calorific value) is determined by subtracting the heat of vaporization of the water vapor from the higher heating value. Beef tallow and some chicken fat contain around 100 ppm of sulfur. Around 2%–12% of fat can be extracted from a feather meal [62]. [1] 43(2001)1027–42.
