Abstract:
The requirement for different types of natural fuel and the peak in the price are big issues for mankind. Researchers are more concerned about using environmentally friendly fuel than limited energy sources
now that public awareness has been raised. Different recyclable energy sources like nuclear, wind, solar,
and biofuels are the best resources, whereas biofuel in different phases has been experimentally performed
as one of the best representative candidates in terms of usage and the production process. The
energy of the biomass is recyclable and also has properties similar to those fossil fuels. To develop the
biodiesel with the help of the transesterification methodology, the catalyst used must be more effective
to ensure faster catalytic activity. In various research journals, different varieties of homogenous type catalyst
are being experimented with, but the reusability of the catalyst is impossible as compared with
heterogeneous catalysts. The biodiesel yield is calculated using response surface methodology and
Chlorella vulgaris algae oil as a feedstock and carbon nanotubes as a heterogeneous nano catalyst. The
present work is performed under 15 experiments by considering 3 parameters: time of reaction, catalyst
concentration, methanol to oil volume, and temperature, which is kept constant at 50 C.
