Abstract
In order to find the influences of antioxidant addition and storage temperature on stability, induction period of safflower biodiesel stabilized with propyl gallate whose concentration spreads from 0 to 5,000 ppm was studied by Rancimat method at the temperature range of 100–120°C. Kinetics on its oxidation was described by the first order rate law. In order to improve the oxidation stability of biodiesel economically, Klason lignin was introduced to supercritical treatment during biodiesel production. It was consequently found that the rapeseed biodiesel prepared by supercritical methanol method at 300°C / 20 MPa for 20 min with a small amount of lignin addition had the induction period longer than 6 h at 110°C in Rancimat test.
