Comparative Study On Carbonized Products Of Poplar And Poplar Particleboard

Currently the chief way to use wasted wood-based panels is to be pulverized to particleboard or other materials. To explore the new approach to recycle wasted wood-based panels, the yield and physicochemical properties of wood vinegar and charcoal, produced by carbonization and pyrogenation process of poplar and poplar particleboard in the different temperature, was mensurated in this paper by contrast test. The paper also analyzed the influence and reason of physicochemical properties of wood vinegar and charcoal in the carbonization temperature and raw materials, providing a theoretical basis for the follow-up production of the waste particleboard vinegar and charcoal. The main results are listed as below,(1) As the carbonization temperature rising, the same quality of poplar and poplar particleboard from charring pyrolysis distillate yield increased, the yield of charcoal decreases the amount of non-condensable gas revenue increase. Compared to the quality of wood vinegar,500℃is the suitable temperature.(2) In the same carbonization temperature, PH and the total volume of poplar particleboard vinegar is greater than poplar vinegar acid PH, and acidity was tested, while acid moisture content and density of poplar particleboard vinegar is less than poplar wood vinegar's, and the color difference is increased with the increasing of carbonization temperature. GC/MS composition analysis showed that poplar particleboard wood vinegar main component is consistent with the aspen, but higher nitrogen material.(3) As the carbonization temperature increased, C element increases in poplar and poplar particleboard, simple pit is got more transparent, and the adsorption for toxic volatile gas is strengthened.
