The production techniques, fuel characteristics, dynamical and economical performances as well as emission characteristics, current situation of application and development prospect of cooking oil biodiesel were comprehensively analyzed. The results showed that cooking oil biodiesel had good renewability, comparative dynamical performance and better emission characteristics than fossil diesel, which was an effective way to achieve the recycling of cooking oil. However, several key problems needed to be solved in the application of cooking oil biodiesel in the car: unperfective preparation process, high viscosity, increasing emission of NOX while burning. Solving above problems was beneficial to truly achieve the economic benefit, environmental benefit and social benefit of cooking oil. |
