Abstract:Coal tar residue
(CTR) is recognized as a hazardous industrial
waste with a high carbon content and coal tar consisting mainly of
toxic polycyclic aromatic hydrocarbons (PAHs). The coal tar in CTR
can be deeply processed into high-value-added fuels and chemicals.
Effective separation of coal tar and residue in CTR is a high-value-added
utilization method for it. In this paper, ethyl acetate, ethanol,
and
n
-hexane were chosen as extractants to study
the extraction process of coal tar fro… Show more
