Transesterification of Nannochloropsis oculata microalga's oil to biodiesel using calcium methoxide catalyst

Biodiesel is an environmental friendly liquid fuel similar to conventional diesel in combustion properties. It has received international attention in recent times, as that biodiesel is renewable, non-toxic and safe to store. In this study, high grade biodiesel was produced from microalgae (Nannochl...
