摘要：

Green house gas emissions and NOx pollutions in China are reviewed in this paper.The effects of the use of lean burn engines in power plant boilers and vehicle engines on green house emission and NOx pollution control are discussed.Based on the relationship between Green house gas emissions and NOx reduction,a combination of in -engine purification with after -treatment technology may be the most reasonable way for the control of green house gas emissions and NOx pollutions at the same time.The requirements of SCR catalysts for power plant stack gas and vehicle exhaust DeNOx are mainly analyzed.Research status,recent progress and development trend in SCR materials are reviewed.High sulfur resistant materials may be the main sources of SCRcatalysts used for DeNOx in China.And low temperature SCR catalysts,still in research phase,provide opportunity for SCR catalyst applications and development in China.SCR catalysts with self-owned intellectual property in China,such as V-W-Ti based SCR catalysts,low temperature SCR catalysts and zeolite based SCR catalysts,are considered as the most promising SCR catalysts for DeNOx in China.
