Mitigation of NOx emission by monophenolic antioxidants blended in POME biodiesel blends

Biodiesel is among the solutions to substitute petroleum‐based fuel. However, the autoxidation ability of biodiesel, which results in degradation of the existing oxygen, has delayed its use on a global level. A potential solution to this problem is the addition of antioxidant additives. Palm oil met...
