| Summary: | The development of biofuels has been the attention of researchers in recent
years, in line with the decline of conventional fuels supply and the increasing of
environmental awareness. Nyamplung oil is one of the raw materials for biofuels
which is renewable, sustainable and eco friendly. In this research, nyamplung oil
converted into biofuel through pyrolysis process. The objective of this research is
to make biofuel that has hydrocarbon fraction close to gasoline from nyamplung
oil and catalyzed by porous carbon.
Pyrolysis of nyamplung oil conducted in batch with fixed bed reactor
made of quartz. Pyrolysis process is done in thermal (non-catalytic) and catalytic.
Before the pyrolysis process started, nitrogen gas flowed into the system for 1
hour. Once the desired temperature is reached, nyamplung oil flowed through a
stack of porous carbon catalyst. Pyrolysis performed in temperature 350, 400, 450
and 500oC. Porous carbon that used in this research is made of polymers
resorcinol phenol formaldehyde ethylene glycol (RPFEG) which has the dominant
structure of mesoporous and microporous. Volume of the liquid yield is recorded
every 30 minutes and the liquid yield for each temperature is analyzed with GCMS
for the identification of its constituent components.
The research results showed that pyrolysis of nyamplung oil with porous
carbon catalyst can produce a liquid product with hydrocarbon fraction equivalent
to gasoline. The dominant mesoporous carbon produces gasoline with higher yield
than the one that produced with the dominant microporous carbon and without
catalyst. The highest gasoline yield of nyamplung oil pyrolysis with the dominant
mesoporous carbon was 84,14%, it was obtained at temperature 350oC.
