Abstract:
Petroleum is non-reneweble fuel sources, its production decline gradually, while
consumption increase significantly. Therefore it is necessary to find a new alternative
energy, such as bio oil from a waste of palm plantation such as stem palm. Stem palm
can be converted to bio oil by pyrolysis process using Ni.Mo/Cengar Clay as a catalyst.
This research is aimed to determine the ratio effect between weight of catalyst (grams)
and sample weight (grams) (0:50; 0,25:50; 0,75:50; 1,25: 50) respectively. In the
pyrolysis process is used 500ml silinap 280-M as heating media and temperature
330oC. The maximum yield of bio oil is around 70,54% under ratio catalyst : sample
(0,75: 50). Bio oil properties having density of 0,988 g/ml, 10,74 cSt viscosity, flash
point 52 0C, and the acidity content 71,34 g NaOH/g sample. Based on GC-MS analysis
is found that bio oil contain several organic compounds, such as acids, ketones,
aldehydes, phenols, alcohols, ect. It can be concluded that bio oil can be further
processed into alternative energy sources instead of petroleum
