Summary : SummaryA catalyst-free and ambient condition dielec. barrier discharge (DBD) plasma torch has been used to efficaciously synthesize partially hydrogenated fatty acid Me ester (H-FAME) obtained from refined palm oil. The electrode configuration was a needle-to-plate type. The effects of power, H2 flow rate, discharge gap, process temperature and reaction duration on H-FAME compositions and properties were examined For 1 h of reaction time, the optimal condition was 100 W input power, 1.0 L/min H2 flow rate, 1.0 cm discharge gap and 90°C reaction temperature Under this condition, the H-FAME contained saturated FAMEs of 56.8% and unsaturated FAMEs of 43.1%, compared to saturated FAMEs of 48.8% and unsaturated FAMEs of 51.0% in the feed FAME. After 1 h of treatment, the oxidation stability increased by 10.7 h (from 12.8 to 23.5 h), while the cloud point increased from 13.5 to 16.0°C. A reduction rate of iodine value was 13.4%/h (reduction from 50.6 to 43.8). The trans-fatty acid formation was not detected in the palm H-FAME. Partial hydrogenation through the DBD plasma torch without using artificial antioxidants or metal catalysts is an environment-friendly and potentially alternative approach, which can substitute conventional catalytic hydrogenation of FAME for enhancing the oxidation stability of biodiesel.
International Journal of Energy Research published new progress about Antioxidants. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate.
