Formulation of gasification rate of char from Eucalyptus camaldulensis grown in arid land on Western Australia

Abstract

During the trial of the afforestation of a dry area in Western Australia for carbon fixation, it was found that Eucalyptus camaldulensis, a species of broadleaf tree, is superior as a plantation tree. Gasification of the trees is a promising energy conversion method which can ongoingly reduce carbon dioxide emissions from the fossil fuel. In the present study, the gasification rate of the char produced by pyrolysis of E. camaldulensis was measured and was found to be reduced at the pyrolysis temperature higher than 1100°C, while it was partly recovered at high conversion. The present phenomena were explained by ash deposit on char surface, which was once released at high conversion.
