- Abstract
The microwave pyrolysis of the low-rank coal is a new technology, which solves the utilization problems of coal cleaning conversion. On basis of experiments, this paper conducted comparative study on microwave co-pyrolysis products of low-rank coal under H2 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 H2 atmosphere was higher than 7.8 wt.%, the bluecoke yield was lower than 4.2 wt.%; The content of S element in the bluecoke obtained under H2 atmosphere was 0.24 wt.% to meet Bluecoke Standard S-1 Grade, and the N element content was just 0.48 wt.%. Furthermore, the content of –OH, C=C and –C?O functional groups in the bluecoke were higher; The alkanes compound content in tar obtained under H2 atmosphere was 13.0 wt.% higher than that under N2 atmosphere, meanwhile, the aromatic hydrocarbons compound content was 34.5 wt.% lower than that under N2 atmosphere.
