STUDI PENGGUNAAN RECYCLE NON-CONDENSABLE PRODUCT SEBAGAI FLUIDIZING GAS PADA PRODUKSI BIO-OIL MENGGUNAKAN PROSES FAST PYROLYSIS
Bio-oil can be produced from biomass with fast pyrolysis process. To facilitate fast heat transfer to quickly heat up the solid phase necessitates the use of inert fluidizing fluid. The cost of inert gas is the main factor that hinders the application of fast pyrolysis commercially. This research is...

description |
Bio-oil can be produced from biomass with fast pyrolysis process. To facilitate
fast heat transfer to quickly heat up the solid phase necessitates the use of inert
fluidizing fluid. The cost of inert gas is the main factor that hinders the application of
fast pyrolysis commercially. This research is directed to investigate alternative
fluidizing gases which are easier and cheaper to be prepared. The objective of this
research was to study influence of operating conditions in a fast pyrolysis process
with re-circulated non-condensable product for producing bio-oil from various
biomasses (corncob, coconut shell, teakwood sawdust and rice husk).
The experiment was done in a fluidized bed reactor equipped with controlled
electric heater and a non-condensable gas re-circulator. A condenser is installed to
separate the bio-oil from non-condensable gas. The non-condensable gas was recirculated back to the reactor. Pyrolysis was done at temperature between 400 °C up
to 500 °C and particle diameters from 0.4 mm up to 1.4 mm and fluidizing gas
flowrate 2 up to 16 L/min. The experiment results show that coconut shell produce more bio oil compared to other materials (up to 77.99 % yield for coconut shell and 44.89 %, 56.69 % and 62.45 % for corncob, teak wood sawdust and rice husk respectively). The highest biooil yield was obtained at the operating temperature for coconut shel, teak wood sawdust, croncob and risk husk respectively 420, 440,500 and 460°C |
