Two Turkish lignites were extracted with tetralin in a batch autoclave under nitrogen atmosphere. Fe 2 O 3 , Mo(CO) 6 , MoO 3 or Al 2 O 3 were used as the added catalyst. The isothermal extraction temperatures ranged from 325 to 425ะŠC, the starting nitrogen pressure ranged from atmospheric to 5 MPa,

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