These drawbacks result in a serious impediment for bio-oil’s practical applications. Although there are many methods for upgrading bio-oil, there is no effective way to solve the problems existing in bio-oil. The aim of the paper is to find a breakthrough from the bio-oil preparation, which using vacuum pyrolysis method to obtain bio-oil from pine straw at bench scale. The influence of temperatures (400-600℃) and biomass dimensions (150-830 μm) on vacuum pyrolysis were investigated. The reaction temperatures were set at 400, 450, 50 |
