Abstract

The experiments on converting Japanese MSW into chlorine-free solid fuel using the combination of the hydrothermal process and the water-washing have been performed. It was observed that after the hydrothermal process, the organic chlorine in the product was reduced and converted into water-soluble inorganic chlorine due to dehydrochlorination effect as well as reaction with the alkaline content of MSW. Water-washing experiments were then conducted to obtain chlorine-free products with less than 3,000 ppm total chlorine content and identify the influencing parameters of chlorine removal by the washing process. In this research, a thermogravimetric analysis to compare the combustion characteristics of products before and after the washing process was also performed.
