摘要
Acacia and Eucalyptus woods were carbonised in the temperature range 400-1200-degrees-C using two different heating-cooling cycles, viz. slow and rapid. The yield of chars and their chemical composition was found to be dependent on the carbonisation temperature, heating rate, soaking time and wood species. The char yield gradually decreased with increase in carbonisation temperature and the majority of volatilisation occurred up to 800-degrees-C. Slow carbonisation resulted in higher char yield than rapid carbonisation. The char yield from Eucalyptus wood samples was greater than from Acacia wood. The carbon content of Eucalyptus wood char was found to be a little higher than Acacia wood char produced under similar carbonisation conditions, possibly due to relatively higher lignin content of Eucalyptus wood.
