BRIQUETTING OF AFŞİN-ELBİSTAN LIGNITE USING BIOMASS AND BINDER ADDITIVES
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2016, Vol 4, Issue 3
Abstract
In this study, a lignite sample from Afşin-Elbistan area of Turkey was briquetted using hazelnut shell, sunflower shell and prina as additives. The lignite and biomass samples were first briquetted separately without blending under pressures of 280, 555, 830 and 1110 MPa. Lignite-biomass blends were prepared to contain 2, 5, 10 and 20 %wt hazelnut shell, sunflower shell and prina as additives. The blends were also briquetted using three different binder materials (molasses, starch and black liquor). Shatter index, compressive strength and water resistance of the formed briquettes were determined and compared. The addition of biomass samples into Afşin-Elbistan lignite were found to affect shatter index positively and to adversely affect the water resistance of briquettes. The addition of 2 %wt prina and sunflower shell into lignite caused a significant increase in compressive strength. Using binder materials affected both compressive strength and shatter index negatively. However, the water resistance of the briquettes increased with the increase in binder material concentration.
