Evaluation of combined lignite cleaning processes, flotation and microbial treatment, and its modelling by Box Behnken methodology
(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
(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
(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 ...
