Abstract:
In this study, system development and experimental investigation were conducted for the fluidized bed fast pyrolysis of rice husk. The design of a fluidized bed pyrolysis system, including a fluidized bed reactor, a feeder, a cyclone and a condenser was developed in detail for the purpose of improving the system performance and efficiency. Rice husk was chosen as the feedstock based on its availability in Taiwan. The product distributions were studied with varying temperature, carrier gas flow rate and biomass feeding. The results showed that the optimal experimental conditions for obtaining the maximum bio-oil yield were at the temperature between 400 oC and 450 oC, the flow rate of 45 L/min and biomass feeding of 21.3 g per inject time. The analysis of GC-MS indicated that the major components of bio-oil contain n-hexadecanoic acid, octadecaoic acid, 9-octadecenoic acid and decanoic acid. The element and property analysis of bio-oil demonstrated that the bio-oil has high oxygen content and low heating value. The analysis of GC-TCD showed that the major components of non-condensable gas are CO2, H2, CH4 and N2.
