Abstract: Abstract Heishan lignite (HL) was extracted with isometric acetone/carbon disulfide mixed solvent under ultrasonic irradiation. The extraction residue (ER) was subjected to thermal dissolution/methanolysis (TD/M) in methanol and catalytic hydroconversion (CHC) in cyclohexane (CH) at… read more here.
