This paper reports on the effects of experimental parameters on the liquefaction yields of Elbistan and Yatagan lignites that were investigated by using different solvents, gases and catalysts. In hydroliquefaction of Elbistan lignite with anthracene and creosote oils, higher oil yields were obtained with anthracene oil. Based on this result, anthracene oil was chosen as solvent for further work done with Elbistan lignite. First, the effect of moisture in lignite samples was observed with synthesis gas as medium gas; then, the effect of carbon monoxide/hydrogen ratio in liquefaction gas mixture was determined using moist lignite samples. The highest oil yield was obtained with most lignite sample in 3CO/1H{sub 2} gas moisture and it was 57.3% (daf.) The hydroliquefaction oil yields of Yatagan lignite obtained with creosote oil were higher than those obtained in anthracene oil. On further work done with Yatagan lignite, creosote oil was chosen as solvent. First, the effects of CoMo and red mud catalysts, then in catalyzed medium, the effects of moisture in lignite samples and at last, using most lignite samples and red mud catalyst, the effects of carbon monoxide/hydrogen ratio in gas moisture, were investigated.
