| Abstract: | ABSTRACT To observe the effect of the heating rate on the desulphurization. Bolu- Mengen lignite was desulphurized in the temperature range of 450-750 °C using flash and slow pyrolysis methods. A reduction of 57.6 % and 34.2 % In the total sulphur was obtained for the slow and flash pyrolysis at a pyrolysis temperature of 750 °C. respectively. It was observed that the flash pyrolysis is shifted toward higher temperatures with respect to the slow pyrolysis. The flash pyrolysis having high thermal efficiency has a potential as a desulphurization process. |
