Contrastive Study on Microwave Pyrolysis Products of Coal under N₂ and Non-N₂ Atmosphere

Abstract:

The microwave pyrolysis is a new research method for deeply processing of coal. This paper researched the microwave pyrolysis products of low rank coal under N₂ and non-N₂ atmosphere. The results showed that, compared with non-N₂ atmosphere, the yield of liquid products increased by 4.65%, while the yield of solid bluecoke decreased by 2.95% under N₂atmosphere. The infrared characteristics absorption peak intensity of bluecoke obtained from N₂ pyrolysis atmosphere was weaker; N₂ contributed to the transformation of heavy oil into light oil.
