Abstract
One of the promising methods to convert waste wood into renewable energy is thermo-chemical methods. Among them, fast pyrolysis of biomass has been studied in many countries in the last decade because biomass can be converted to a liquid fuel which has higher energy density. During fast pyrolysis, waste wood is rapidly heated in the absence of oxygen and this results in the different amounts of char, gas, and pyrolysis oil, depending on the feedstock and process conditions. The most previous studies of fast pyrolysis focus on the characteristics of fast pyrolyzer to increase the yield and quality of bio-oil. However, one of very important aspects for designing fast pyrolysis plant is volatile condensation process. In order to minimize secondary reactions and maximize oil yields, pyrolysis vapors must be quenched and condensed very rapidly. Nevertheless, the study on the volatile condensation after fast pyrolysis is still insufficient due to the complicated physical phenomena. Therefore, this study is carried out to examine the characteristics of bio-oil by changing condensation conditions, especially for the yield and water content.
