A study of feasibility evaluation of biodiesel production from Camelina sativa grown in Nova Scotia

Description: Biodiesel, a renewable, biodegradable and environmentally innocuous biofuel, has shown great potential to be used as a substitute for conventional petro-diesel. Camelina sativa has recently attracted great interest as an energy crop for biodiesel production in North America. To assess the feasibility of biodiesel production from camelina, the cultivation conditions, camelina oil fatty acid profile, alkali-catalyzed transesterificaiton process and fuel properties of camelina biodiesel were investigated. Unrefined camelina oil, containing 10%, 33.2% and 56.8% saturated, monounsaturated and polyunsaturated fatty acids respectively, was used to synthesize biodiesel. A high conversion rate of 96% was obtained under optimal reaction conditions of 38.7°C reaction temperature, 40 min reaction time, 7.7 molar ratio of methanol/oil, and 1.5 wt.% potassium hydroxide catalyst concentration. Most fuel properties of the resulting camelina biodiesel were in good agreement with specifications of the American Society for Testing and Materials (ASTM D6751) and European standard (EN 14214), such as kinematic viscosity, acid number, flash point, sulfur content, total glycerol content. However, camelina biodiesel exhibited poor oxidative stability (1.9 h) resulting from the high percentage of polyunsaturated fatty acid methyl esters. Adding suitable amount of antioxidants would be a promising solution to improve the oxidation stability of camelina biodiesel.
