Abstract

This work is to study the efficiency of bio-oil production with and without bio-oil scrubber in a circulating fluidized bed reactor. Napier grass was used to be a raw material for pyrolysis process. The experiment was performed at biomass feed rate of 45, 60, and 75 kg/h, the temperature from 440°C to 520°C and the superficial velocity of 7 m/s. The effect on temperature and feed rate of the pyrolysis process, bio-oil properties, cold efficiency and energy conversion were studied. The experimental results show that the maximum yield of pyrolysis oil with and without bio-oil scrubber were 44.60wt% and 43.73wt%, respectively. The properties of bio-oil were investigated and it was found that the Higher Heating Valuer (HHV), cold efficiency and energy conversion in this system were 12.29 MJ/kg, 29.94%, and 20.66%, respectively. The bio-oil scrubber can improve the bio-oil production with the increasing of bio-oil yield of 1.99% compared with the system without bio-oil scrubber and it can solve the problem in fluidized bed reactor.
