The effect of heat treatment on bio-oil properties obtained fromn pyrolysis of wood sawdust

摘要

Heat treatment is becoming increasingly popular and is growing as an industrial process to improve wood properties. The Finnish wood heat treatment technology, ThermoWood, is the most commonly used technology in the industrial area. In this study, pyrolysis of untreated and heat-treated ash wood (Fraxinus excelsior L.) was carried out using a fixed-bed reactor at different pyrolysis temperatures. The influences of the heat treatment process and the pyrolysis temperature on the yields and chemica
