⚡ TL;DR(Too Long; Didn't Read)

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.

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.

Özet

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
