THE PRODUCTION OF GOOD QUALITY SOLID FUEL FROMLOW GRADE LIGNITE AND WASTE TYRE CO CHEMICALPROCESS

Abstract

By the year 2013 che lignite mine reserves in Turkey were determjned be 13.3 tons. These lignite contain high levels of ash, humidity, and suiphur. Because of their high ash, humidity, and sulphur contents such coals deemed as low qua:žty when bu.er!ed or gasified for electricity production are•known to cause environmental Tae ft!bber based wastes such as expired tires and the scrap side products during their that may be vulcanized or nor. arp Ollâlifpd Hinrn;a« Thp nnarfiirv ri•a; in Turkey is around 300,000 tons per year. In this study, ci- emir-a! degraeac:cn itudies of the waste tyre rubbers crumb-Low Rank Lignite mixture were tamea catusi,-rg cxiciacive cleavage by inorganic and organic chemicals to decompose easily on account of {ink;ng and stabilizers.it is aimed that both the waste tire degradation. and the scraping of as-. and sulfur from the lignites have been performed with a co-process and c.'ót?ir.ee che caloric value coal resembling solid products. Experimental were performed in these stages; I)The preparation of waste tires and lignite samples and anaiysis, 2) degradation of the waste tire and lignite together and obtain a solid product, of the solid product and .the analysis of sufur and ash removal efficiencv.Elemer.r.è! of the waste tyre rubbers crumb, lignite and solid products was perforrned Q!'

C, H, S, O represent carbon, and oxygen content of material, respectively, expressed in % by mass 3e-šmination of ash, moisture and volatile matter was performed according ASTM surface morphology of solid product was performed bu means c..í a scannir;e 23ectrcr, m;croscope (SEM-ZEISS Supra 40VP). BET surface area measurements using N. gas isotherms were completed with a Micromericics ASAP 2020 gas adsorptic,r. Infrared analyses were obtained using Perkin Eirner Sr,ectrurn ICO m,cdž; with (ATR). Density measurements by Cas pycnomete:- (Mic - TL.•pyc il 1340).As a result, the reduction of ash and sulfur content was and the idea of the utilization of low quality coal together with the :.rž the ?.ptfication of the chemical degradation results obtained are promising
