Abstract :The aim of this study was to investigate the use of various vegetable oils insert ignore into journalissuearticles values(almond oil, hazelnut oil, poppy oil, soybean insert ignore into journalissuearticles values(soya); oil, sunflower oil); for Sivas/Gemerek insert ignore into journalissuearticles values(in Turkey); lignite coal by oil agglomeration. The study examined the effect of bridging liquid type and dosage on oil agglomeration. Vegetable oil dosages of 2%, 5%, 10% and 20% were investigated in oil agglomeration experiments. The agglomeration of lignite coal with these bridging liquids was evaluated based on yield, combustible recovery and ash rejection. The agglomeration performances of these vegetable oils were compared. The highest ash rejection insert ignore into journalissuearticles values(70.30%); was observed by using soybean insert ignore into journalissuearticles values(soya); at 20% of the bridging liquid dosage. The yield and combustible recovery of lignite coal were achieved 36.46% yield and 38.05% combustible recovery in this soybean insert ignore into journalissuearticles values(soya); oil dosage, respectively. The lignite coal ash content was reduced from 19.08% to 15.54% under these optimum conditions.
