【Abstract】 The exist forms of sulfur and nitrogen and their transformation behavior during coal pyrolysis have been briefly reviewed. The distribution of sulfur and nitrogen species among gas, liquid and solid products are also presented and evaluated simultaneously. A new coal combustion process which removing SO 2 and NO x simultaneously based on decoupling principle is also analyzed. Several research hotspot topics which are useful to decrease or control sulfur and nitrogen emissions are pointed out.更多还原
