Abstract

Microwave pyrolysis is a new research method for deeply processing of low-rank coal. This paper conducted comparative study on microwave co-pyrolysis products of low-rank coal under CH4 and N2 atmosphere, respectively. The composition and content of tar and bluecoke were analyzed by gas chromatography-mass spectrometry and fourier transform infrared spectrometer. The results indicated that compared with N2 atmosphere, the yield of liquid products (tar and pyrolysis water) obtained under CH4 atmosphere increased by 5.4 wt.%, whereas the bluecoke yield decreased by 3.0 wt.%; The content of S element in the bluecoke obtained under CH4 atmosphere was less than 0.30 wt.% to meet Bluecoke Standard S-1 Grade, and the ash content was just 6.72 wt.% to meet Bluecoke Standard A-3 Grade. Furthermore, the content of –OH C=C and –C O functional groups in the bluecoke were higher; The alkanes and olefins compound content in tar obtained under CH4 atmosphere were 9.1 wt.% and 7.9 wt.% higher than that under N2 atmosphere, meanwhile, the aromatic hydrocarbons compound content was 35.5 wt.% lower than that under N2 atmosphere.
