Abstract：The research progress and characteristics of the domestic and international mainstream pulverized coal pyrolysis upgrading tech-nologies were introduced in details in order to improve the quality,economy and security of low rank coal.The technical problems existed were analyzed and developing suggestions were proposed for the low rank pulverized coal pyrolysis upgrading technology.The results showed that it was one of the key technologies to use solid heat carrier pyrolysis process for pulverized coal utilization,which have the advantages of high heating speed,high tar yield and calorific value.Due to the issues such as key technical deficiency,low economic efficiency,big tar quality fluctuation and difficult waste water treatment,the research in future should focus on the fields of key technical breakthrough,pyrol-ysis reactor optimization,pyrolysis products deep processing and utilization,tar yields and tar quality improvement,tar separation and re-covery technology,organic waste water treatment and poly-generation technology with high energy conversion efficiency.
