Abstract:

Biofuel production from algae using hydrothermal conversion technology is novel and the studies proved the feasibility of producing biofuel precursors such as biofuel to replace significant quantities of petrocrude used for the production of diesel, petrol and jet fuels. Three microalgal samples Botryococcus sp., Chlorella sp. and Tetradesmus wisconsinensis were selected and screened for fast growth and high oil content. Proximate composition of microalgal isolates was studied and the values of proximate composition such as moisture content, volatile matter, ash content and fixed carbon are resulted. Among all three algal strains, T. wisconsinensis is suitable for analysis, which results 3.7 per cent of moisture, 82.5 per cent of volatile, 2.4 per cent of ash and 11.1 percent of fixed carbon. The thermo gravimetric (TGA) and derivative thermo gravimetric (DTG) curves of the algae at heating rate of 40 in nitrogen revealed three stages of thermal decomposition for all the three microalgal isolates. The final weight loss from all the three isolates lies in the range of 53 to 74 per cent.
