Abstract: The paper introduced the research progress on the lignite themolysis technology of the solid heat carrier at home and abroad.The comparison and analy sis on the themolysis technique of the solid heat carrier and the coupling themolysis technology as well as the catalysis performances of the applied solid heat carrier W ere conducted. The study results showed that the coupling low temperature themolysis multi link production technology of the circulating fluidized bed would be a suitabl e technique to clean and high efficient comprehensive utilization of lignite.The author pointed out that the integrated technique would not only optimize the product com position,improve the production rate and increase the energy utilization efficiency,could realize the heat,electric power,gas,oil,coke and other multi production and suppl y and could improve the coal comprehensive utilization value.In addition,according to the problems existed in the solid heat carrier and the preparation,the relative impr oved proposals and future research prospects were provided.
