Abstract:In order to investigate pyrolysis characteristics of disused composite panels and promote directional application value of its pyrolysis products, the disused particle boards (PB) and middle-density fiber boards (MDF) were treated at 300,400,500 and 600℃ of pyrolysis temperature in a telecontrol furnace with two increasing rates of 100 and 150℃/h. Effects of different terminal temperatures and rates of temperature increment on pyrolysis process and product yield were analyzed. The pyrolysis characteristics of disused composite panels and properties of its products were studied based on physicochemical properties of solid and liquid products. The results showed that smoke temperature peaked during the pyrolysis process corresponding to the inner furnace temperature at 150 and 250℃.The pyrolysis degree of MDF was stronger than that of PB at the same condition. The collection rate of solid and liquid products decreased and gas collection rate increased when increasing the terminal temperature. The condensed liquid from MDF and the solid charcoal both from MDF and PB showed alkalescent while the condensed liquid from PB was weak acidic. The organic elemental analysis of solid products revealed that the relative contents of N and H elements reduced and C element content increased when increasing the terminal temperature. The relative content of N element in the carbonized products from MDF was higher than that from PB.
