For the purpose of developing a low cost bio-oil production process, we have investigated rapid pyrolysis of woody biomass by using an entrained flow reactor as the key device. The entrained flow reactor was selected because of the fine controllability of reaction temperature and residence time, which were the main factors affecting liquid products yield. In the bench-scale testing facility with entrained flow reactor, wood particles were rapidly pyrolized and the products were collected to analyze. The yield of bio-oil was higher than 50wt% compared with the fed biomass in dry weight. The obtained bio-oil formed two layers, which were hydrophilic layer containing condensed water and hydrophobic layer settled on the bottom. The moisture of hydrophilic layer should be removed and the products are expected to use as an alternative to heavy fuel oil.
