Biodiesel Production from Unused Mixed Culture of Algae
The main constraints for biodiesels are their high market price. Most of the resources of energy are concerned with higher pollution in the environment. Algae, from that point, are the better feedstocks to produce fuel. Algae cut down environmental pollution by using carbon dioxide at the time of photosynthesis. Algae have comparatively higher oil content than other crops. In this experiment, algae, which remain unused and thrown away from a canal at Ludhiana city of India, were used to produce biodiesel. Those algae were dried completely in the sun. Oil extraction from these dried algae was carried out by Soxtherm using n-hexane. Extraction of 10% oil took place in this process. Biodiesel was produced by transesterification of the algal oil. The optimized conditions to produce biodiesel were molar ratio of 6:1, catalyst concentration of 2%, reaction temperature of 62 °C and reaction time of 60 min.
