Abstract: Diesel combustions produce greenhouse and harmful gases bringing health hazards and negative impact to environment. This study produced biochar from waste palm shell and the biochar was further applied as fuel additive in biodiesel to reduce the nitric oxides emission. The biochar showed high fixed carbon content (85.8 wt%) and low ash content (2.0 wt%). Subsequently, the biodiesel post-combustion emission of NO_X recorded a significant reduction up to 40.6% compared to without application of biochar. This study shows that the mixing of biochar in biodiesel is a potential approach to reduce the nitric oxide emission.
