Abstract

Activated carbon was especially produced from wood, lignite, organic agricultural wastes such as coconut shale. In this study, high sulfur contained coal was used as a precursor to production of activated carbon. In the activated carbon production, physical activation method was applied and several operation parameters such as activation temperature (350-950 oC), activation time (5- 120 min.) and particle size of coal samples (0,25-2 mm) were investigated. High sulfur contained coal samples has 56 m2 /gr BET surface area. Produced activated carbons at optimum conditions have 485 m2 /gr and 510 m2 /gr BET surface areas in any gas inherent media and N2 gas media, respectively. Furthermore, abilities of removal of Cu2+ ions from solution of produced activated carbons were investigated. In both operation conditions, approximately 97% Cu2+ ions in solutions can be removed. As a result, it was determined that high sulfur coals caused environmental problems can be used in non-fuel areas.

Özet

Aktif karbon, genellikle odun, kömür, Hindistan cevizi kabuğu gibi çeşitli zirai atıklardan üretilmektedir. Bu çalışmada, aktif karbon üretilmesi için hammadde olarak yüksek oranda kükürt içeren kömür kullanılmıştır. Aktif karbon üretiminde fiziksel aktivasyon yöntemi uygulanmış, bu yöntemde etkili olan aktivasyon sıcaklığı (350-950 oC), aktivasyon süresi (5-120 dakika), tane boyut (0,25-2 mm) gibi değişkenlerin etkileri araştırılmıştır. Aktif karbon üretiminde hammadde olarak kullanılan kömür numunesinin BET yüzey alanı 56 m2 /gr iken en uygun çalışma şartlarında herhangi bir gaz girişinin olmadığı işlemde elde edilen aktif karbonun BET yüzey alanı 485 m2 /gr ve inert bir gaz olan N2 ile yapılan işlem ile elde edilen aktif karbonun BET yüzey alanı 510 m2 /gr olarak ölçülmüştür. Ayrıca elde edilen aktif karbonun çözeltiden Cu2+ iyonlarını uzaklaştırma kabiliyetleri incelenmiştir. Her iki çalışma şartlarında çözeltideki Cu2+ iyonlarının yaklaşık %97’si uzaklaştırılabilmiştir. Yapılan bu çalışma ile çevresel sorun oluşturan yüksek oranda kükürt içeren kömürlerin yakıt dışı alanlarda kullanılabileceği belirlenmiştir.
