Primary Pyrolysis and Secondary Reaction Behaviors as Compared Between Japanese Cedar and Japanese Beech Wood in an Ampoule Reactor

Abstract

The purpose of this work is to understand the primary pyrolysis and secondary reaction behaviors of two distinct groups of woody biomass, i.e., softwood and hardwood by using Japanese cedar wood (a softwood) and Japanese beech wood (a hardwood). Their demineralized samples were also used in order to understand the influences of inorganic substance. Heat-treatment was conducted under the conditions of N2 / 600°C / 40-600 s in an ampoule reactor. In this paper, some characteristic features of these wood samples are reported and discussed with the different chemical structures of lignin and hemicellulose as their composing polymers. © Springer 2010.
