Direct liquefaction of high-sulfur coals: Effect of the catalyst, the solvent, and the mineral matter

Gözmen, Belgin; Artok, Levent; Erbatur, Gaye; Erbatur, Oktay (American Chemical Society, 2002-09)

Two low-rank coals with high sulfur contents (Gediz subbituminous coal: 7.6 wt % S:dry basis. Çayirhan lignite: 5.7 wt% S:dry basis.) were subjected to hydroliquefaction. Liquefaction conditions included dry or solvent ...
The effect of additives on hydrodesulfurization of dibenzothiophene over bulk molybdenum sulfide: Increased catalytic activity in the presence of phenol

Gül, Ömer; Atanur, Osman M.; Artok, Levent; Erbatur, Oktay (Elsevier, 2008-04)

The effect of various additive organic reagents on the activation of MoS3 as molybdenum sulfide catalyst precursor during hydrodesulfurization reaction of dibenzothiophene was studied. It was found that the presence of ...
