Konversi Kayu Ketapang (Terminalia Catappa. L) Menjadi Bio-Oil Menggunakan Metode Pirolisis Dengan Katalis Co-Mo/NZA

Abstract

The demand of fossil fuel  is increasing each year. On the other hand,  the availability of
conventional petroleum fuels diminishing due to its non-renewable. Therefore, it is necessary to
develop  a  new alternative  fuel  that can be renewed,  one of the solution  is the  processing of
biomass into bio-oil. Bio-oil is a result of the pyrolysis of biomass. Availability of Ketapang rod
is converted  into bio-oil by pyrolysis method using catalysts natural zeolite. The purpose of this
study was  to  determine the performance of  the catalyst  to  produce bio-oil,  characterize  the
density, viscosity, acid number, and flash point of bio-oil  that produced, as well as analyze  the
chemical components  of bio-oil  by GC-MS method.  Pyrolysis of  Ketapang rod  catalyst  from
natural zeolite  in the reactor  slurry  do  by feeding 50 grams with the size    -100 +200 mesh,
silinap 500 ml, stirring speed is set to 300 rpm, 320o
C temperature, and the process runs for 120
minutes. The results showed that the optimum yield obtained  on 2.5% catalyst, amounting to
77%. The test results obtained by the physical properties of density 0.875 g/ml, 9.56  cSt
viscosity, acid number of 49,89 gr NaOH/gr sample.
