system development and product analysis for the fluidized bed fast pyrolysis

Abstract

In this study both system development and experimental investigation were conducted for fluidized bed fast pyrolysis The design of a fluidized bed pyrolysis system including a fluidized bed reactor a feeder a cyclone and a condenser was carried out in order to improve the system performance and efficiency Rice husk was chosen as the feedstock based on its availability in Taiwan The product distributions from fluidized bed pyrolysis 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 ℃ and 450 ℃ 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
