3. Biodiesel
Biodiesel is a promising alternative in renewable fuels production
decreases amounts of carbon dioxide
decrease dependence on fossil fuels
improve the rural economics

5. Hydroprocessing
Decarboxylation H2 H2
Decarbonylation
Deoxygenation

6. 2nd generation of biodiesel
There are many advantage over trans-esterification method
Obtain product hydrocarbon like fossil fuel
Product is high cetane number and heating value
Product can blend with diesel fossil fuel more than 5%

15. Conclusions
The addition of tungsten can improved the product yield and catalytic activity
The suitable condition of this process is at temperature 350°C and pressure 40 bar in 2hr
The selectivity of product decreased with increasing temperature over 350°C and reaction time
