Two Turkish lignites were extracted with tetralin in a batch autoclave under nitrogen or hydrogen atmosphere. The isothermal extraction temperatures ranged from 325 to 425°C at 25°C intervals and the isothermal extraction periods were 0, 30, 60 and 120 min. After removal of char and solvent, the rem
