To estimate reactivity such as char yield and ash melting for softwood pellets during gasification CHP process, Japanese cedar and German spruce pellets were employed to thermogravimetry, proximate analysis and chemical composition analysis. Then we found that Japanese cedar showed higher fixed carbon content and mass yield from proximate analysis and thermogravimetry, suggesting that higher char yield during gasification. That was supported from the higher cellulose and lignin content of Japanese cedar. Furthermore, Japanese cedar contained a large amount of alkali metals and silica contents, suggesting that the molten alkali metal easily forms larger clinker at lower temperature with involving the surrounding char.
