Abstract

Fast pyrolysis was performed with small diameter woody biomasses (Larix Kaempferi and Quercus mongolica) in the fluidized bed reactor under the temperature ranges between 450 and 500°C at the residence time of 1.3 second. Three pyrolytic products (bio-oil, bio-char and gas) were investigated by means of various analytical methods. The yield of bio-oil was determined to 60.6-66.7 wt% for Larix Kaempferi and 59.7-64.4 wt% for Quercus mongolica, respectively. The lowest yield of bio-oil was observed at temperature of 550°C in both feedstocks. As a result of the physicochemical analysis, the water content of biooil showed the lowest at 500°C in both Larix Kaempferi and Quercus mongolica (Larix Kaempferi 25.9%, Quercus mongolica 25.3%). According to GC/MS analysis, 36 pyrolysis products were identified from the bio-oil. Acetic acid, levoglucosan, ketone related compounds were produced as major pyrolysis degradation products.
