Syngas: Derived from biodiesel and its influence on CI engine

Nowadays biodiesel usage is widely adopted in internal combustion engine because of availability and lower exhaust emissions. During the biodiesel production around 10% glycerol is obtained as a byproduct, and this can be efficiently used in CI engines. In this paper the crude glycerol obtained from the trans-esterification process of biodiesel is used to produce hydrogen enriched syngas, through water mixture by directly injecting it into a fast thermal cracking reactor at different temperature such as 600 degrees C, 650 degrees C, 700 degrees C and 750 degrees C. The yield of syngas at different temperatures and different glycerol water proportions are analyzed. It is seen that the addition of water has improved the syngas yield and also increased the proportion of hydrogen in the syngas up to 80%. Further the performance and emission study of the syngas in a compression ignition engine showed significant reduction in smoke and NO emission simultaneously. (C) 2019 Elsevier Ltd.
