Title

Treatability of Beech and Pine wood with pyrolysis acids produced from different species of Wood

Pages

  88-101

Abstract

 Pyrolysis acid or wood vinegar is a dark liquid derived from the condensation of steam and volatile compounds emitted by thermal pyrolysis of wood or any other lignocellulosic material. In this study, a heating furnace was first designed to allow a precise temperature-time program of pyrolysis. The wood from three different species including oak, citrus and cypress were pyrolyzed under a specific temperature-time schedule. The gases emitted from the furnace were cooled and condensed in a 20 m pipe ooled with flow of cold water, and then the condensate of was dumped in a container. Pyrolysis was performed at three different temperature ranges of 200, 260 and 330 ° C. The obtained pyrolysis acids had different color and acidity depending on the temperature and spieces of wood used. Under the heating conditions used in this study, cypress had lower pyrolysis rate than hardwoods. The weight percentage gain of the treated beech and pine wood varied from 5 to 35%, which was depended on the temperature as well as the wood used for pyrolysis. Acid pyrolysis at higher temperatures resulted in higher weight percentage gain. The Acid pyrolysis obtained at lower temperature was leached at higher rates from treated wood. Also the wood types used for pyrolysis had significant effect on the amount of tar from treated woods.
