This paper presents the result of a detailed study on the dechlorination at various atmospheres of low bituminous Turkish lignite chlorinated in water media. In this study, the effects of the ratio of steam (5-60% of steam), temperature (300-550 degrees C) and coal treatment time (0-1800 s) in nitrogen atmosphere containing 60% of steam, and gas flow rate (700-4750 ml min(-1)), temperature (250-550 degrees C) and coal treatment time (0-3600 s) in nitrogen atmosphere on chlorine removal have been investigated. It is shown that steam has an increased effect on chlorine removal. The remaining chlorine content in coal was found to be 0.045 wt.% of coal (this is much lower than the chlorine content of 0.14 of the raw coal) in nitrogen atmosphere containing 60% of steam at 550 degrees C. Original chlorine in the coal, in addition to the chlorine taken by the coal during chlorination is also removed by this method. (C) 2000 Elsevier Science Ltd. All rights reserved.
