碩士 / 大仁科技大學 / 環境管理研究所 / 98 / Microalgae, due to the advantages of higher photosynthetic efficiency, higher biomass production and faster growth compared to other energy crops, as a potential source of bioenergy has attracted wide attention. Microalgae are photosynthetic microorganisms that convert sunlight, water and carbon dioxide to algal biomass. Many microalgae are exceedingly rich in lipid, which can be converted to biodiesel.
To understand the effect on the biodiesel production via transesterification of microalgae, four factors such as such as alkaline catalyst amount, reaction temperature, reaction time, and acid catalyst amount were investigated using two level four factor full factorial design in this study. Under experimental range considered the most important factor on the biodiesel production of transesterification is the alkaline catalyst amount. For the biodiesel production of biomass, this factor has a positive influence, resulting in an increase of fatty acid content. The reaction time and acid catalyst also have a positive influence respectively. The reaction temperature, however, has a negative influence. There is an appreciable interaction between alkaline catalyst amount (variable 1) and reaction temperature (variable 2), the effects of these variables must be considered jointly. The best results for laboratory scale tested on the biodiesel production via transesterification were obtained at dosage of 8 meq alkaline catalyst, with acid catalyzed, 100℃of reaction temperature, and 30 min of reaction time.
