准东煤与污泥共热解过程中NOx前驱物释放规律
Release of NOx precursors in co-pyrolysis process of Zhun Dong coal mixed with sludge
摘要
Abstract
The TG-MS,ICP-OES andin situ DRIFT were used to analyze the release of NOx precursors in the co-pyrolysis process of Zhun Dong coal mixed with sludge. In this experiment, the different proportion blends of sludge and coal with sludge percentage of 25%, 50% and 75% were tested under the same conditions. The effects of minerals and functional groups on the release of NOx precursors were investigated. The results indicated that the yields of NH3 and HCN did not increase with increasing the percentage of sludge in samples, but there was an optimum distribution of 50% to decrease the yields of NOx precursors in the process of co-pyrolysis. Minerals in Zhun Dong coal and synergistic effect of various functional groups in process of mixed pyrolysis had an inhibitory effect on the release of NOx precursors.关键词
