Evaluation of combined lignite cleaning processes, flotation and microbial treatment, and its modelling by Box Behnken methodology
Koca, Sabiha; Aksoy, Derya Oz; Çabuk, Ahmet; Çelik, Pınar Aytar; Sagol, Ercan; Toptas, Yağmur; Koca, Hüseyin (Elsevier Sci LTD, 2017)In this study, first, the physicochemical cleaning of Cayirhan region's low-quality lignites was investigated by flotation to reduce ash content. In the flotation experiments, the effects of collector dosage, frother dosage, ... -
Isolation and characterization of native microorganism from Turkish lignite and usability at fungal desulphurization
Aytar, Pınar; Aksoy, Derya Oz; Toptas, Yağmur; Çabuk, Ahmet; Koca, Sabiha; Koca, Hüseyin (Elsevier Sci LTD, 2014)In this study, microorganisms were isolated from Mihaliccik region (Eskisehir, Turkey) lignites with low rank and high ash and sulphur content. A series of heavy liquids (from 1.3 g/ml to 1.9 g/ml) were used to determine ... -
Physical and physicochemical cleaning of lignite and the effect of cleaning on biodesulfurization
Aksoy, Derya Öz; Aytar, Pınar; Toptas, Yağmur; Çabuk, Ahmet; Koca, Sabiha; Koca, Hüseyin (Elsevier Sci LTD, 2014)In this work, physical, physicochemical and biological processes were combined to decrease the sulfur and ash content of finely ground coal. Two separation methods - flotation and a multigravity separator (MGS) - were ...
