Abstract: 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 °C, 650 °C, 700 °C and 750 °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.
