Distribution of rapid pyrolysis products for Hami lignite and its light residue.

ABSTRACT: Naomaohu lignite (NL) from Hami, Xinjiang, was ultrasonically extracted with a mixed solvent of CS₂ and acetone (in equal volumes) to obtain the extract residue (ER). The ER was then separated based on density differences with CCl₄ to yield the corresponding light residue (NL-L). The composition and structural characteristics of the light residue were characterized by proximate, ultimate, infrared, and thermogravimetric analyses (TG-DTG). The difference in the distribution of pyrolysis products between NL and NL-L was studied with rapid pyrolysis equipment (Py-GC/MS). The results showed that solvent extraction and density difference can reduce moisture and increase volatile matter. The relative content of oxygen-containing functional groups and aromatic functional gro
