Key Points

Pore size distribution changed significantly under temperature treatment, impacting coal's overall structure.
Findings indicate variations in pore characteristics over time due to temperature influence in LF-NMR assessments.
Analysis of coal samples involved low-field nuclear magnetic resonance techniques combined with thermal treatment procedures.
Understanding pore alterations has implications for coal's usage and efficiency in energy production.

Implication

Analysis of coal's pore size distribution reveals significant changes under varying temperature conditions, suggesting stronger structural insights.

Abstract

This study employed LF-NMR combined with oil bath heat treatment experiments to systematically characterize variations in T 2 relaxation spectra, pore size distribution, throat structure, and porosity in coal samples.
