煤炭中氢含量与挥发分的太赫兹时域光谱研究
Analysis of Hydrogen and Volatile Matter Content in Coal Maceral Using Time-Resolved Terahertz Spectroscopy
摘要
Abstract
We apply terahertz time domain spectroscopy (THz-TDS) transmission mode to measure a serious of hydrogen content (from 2.14 to 4.7% by weight) and volatile matter content (from 5.58 to 33.97% by weight) in coal maceral.The THz absorption coefficient and relative dielectric permittivity of coal maceral depende negatively linear on the hydrogen content and volatile matter content in the frequency range from 0.2THz to 1.4THz.The present identification based on THz-TDS was in agreement with established view on proportional to the relationship of Hdaf (hydrogen content) and Vdaf(volatile matter content),what suggested THz technology can act as a valuable tool for monitoring and inspecting hydrogen content and volatile matter content in coal maceral.关键词
