Catalytic Cracking Serbuk Gergaji menjadi Crude Biofuel
Abstract: The need for sources
of energy continues to rise and oil reserves as the main sourceof energy that
continues to thin out the main reason for the importance of seekingalternative
energy sources instead of petroleum. Biomass especially merantisawdust
contained in Riau can be bio-oil through pyrolysis catalytic. This studyaimed
to determine the effect of temperature and percentage of ZSM-5 to yield bio-oil
produced and to know the characteristics of bio-oil properties including
density,viscosity and flash point. The research prosedure is as followed
Meranti sawdustweighing 50 grams that is inserted into the reactor was filled
with 500 ml silinapthen added catalyst ZSM-5 with a weight of 1 wt% bio-mass
and reactor coupledwith a condenser and nitrogen gas flowed at a flow rate of
1:35 ml / sec. Then inthe pyrolysis at temperatures of 290-320 oC to form
products which will furthercondensed. The liquid condensed and collected every
10 minutes in record volumeand weight to calculate yield and stopped at 120
minutes. The experiment wasrepeated at temperatures of 320 oC with a percentage
of catalyst 2%, 3% and 4% b yweight of the biomass. From this research, it was
indicated that temperature andZSM-5 increases the rate of pyrolysis reaction.
Optimum conditions for thepyrolysis at temperatures of 320 oC and the
percentage of ZSM-5 catalysts 4% b yweight of biomass with a yield of 58%. From
the results of physicalcharacterization of bio-oil is known density = 0978 g /
ml, viscosity 19.96 cp = 52°C and a flash point.
