Interactions Between Components in Coking of Coal Blends

Year 2004, Volume: 43 Issue: 4, 29 - 40, 01.12.2004

Abstract

This study has been carried out for the purpose of determination of interactions among the
components in coal blends during the coking process. For this purpose, the blends of cokable
Zonguldak coal (ZK) with air-dried (TK), semicoked both at 550°C (TK550) and 900°C (TK900)
Tunçbiiek lignite were prepared. The plasticity, dilatation, contraction of these blends and the strength
of the cokes produced from these blends were determined.
The experimental data obtained were evaluated and it was determined that the lignite, when
carbonised at about 500 °C, completes its chemical breakdown, terminates the evolution of its volatile
matter and contraction process, improves its surface wetting behavior and thus exhibits the most
favorable properties as far as the cokability of coal blend is concerned.

KÖMÜR KARIŞIMLARININ KOKLAŞTİRÎLMASINDA BİLEŞENLER ARASI ETİKİLEŞİMLER

Year 2004, Volume: 43 Issue: 4, 29 - 40, 01.12.2004

Abstract

Bu çalışma koklaşma işleminde, kömür karışımlarını oluşturan bileşenler arasındaki etkileşimin
incelenmesi amacıyla yapılmıştır. Bu amaçla, koklaşma özelliği olan Zonguldak taşkömürüne (ZK)
havada kurutulmuş (TK), 550°C'de (TK550) ve 900°C'de (TK900) karbonize edilmiş sert Tunçbiiek
kömürleri karıştırılarak karışımlar hazırlanmıştır. Bu karışımların plastikleşme, dilatasyon, büzülme
özellikleri ve bu karışımlardan üretilen kokların sağlamlıkları belirlenmiştir.
Elde edilen deneysel veriler değerlendirilmiş ve linyit kömürü 500 °C civarında karbonize edildiğinde,
kimyasal parçalanmasını tamamlayarak gaz çıkışını ve büzülmesini kaybettiği, yüzey ıslanma
özelliğinin arttığı ve dolayısıyla da koklaşan kömüre karıştırmak için en uygun özelliği kazandığı tespit
edilmiştir
