Abstract

Hydrothermal pretreatment was applied to wood sawdust, Trakya lignite and wood sawdust-Trakya lignite mixture (50%, wt) individually. Changes in fuel properties and thermochemical conversion characteristics of each were observed. In addition, the synergistic effect of biomass on coal with hydrothermal pretreatment of the mixture was investigated. After hydrothermal pretreatment, where the optimum conditions were 230 °C and 90 minutes and under autogeneous pressure, fixed carbon percentage and heating value increased and ash content decreased in all fuels. Compared to lignite and wood sawdust, a fuel with higher elemental carbon content, lower oxygen percentage and higher calorific value was obtained when the mixture was co-hydrothermally pretreated. Hydrothermal pretreatment applied to the mixture modified the structural properties and volatiles of the mixture. For this reason, the reactivity of the hydrothermal pretreated mixture in pyrolysis and combustion reactions increased, and the peak temperatures at which the mass loss rate was maximum were shifted to higher.

Özet

Odun talaşı, Trakya linyiti ve ağırlıkça %50 odun talaşı-Trakya linyitinden oluşan karışıma ayrı ayrı hidrotermal ön işlem uygulanmıştır. Her birinin yakıt özelliklerindeki ve termokimyasal dönüşüm karakterlerindeki değişim gözlemlenmiştir. Ayrıca, karışımın hidrotermal ön işlemiyle biyokütlenin kömür üzerinde sinerjik etkisine bakılmıştır. Optimum şartların 230 °C ve 90 dk olduğu ve otojenik basınçta gerçekleşen hidrotermal ön işlem sonrası tüm yakıtlarda sabit karbon yüzdesi ve ısıl değer artmış, kül içeriği azalmıştır. Linyit ve odun talaşına kıyasla, karışıma beraber hidrotermal işlem uygulandığında daha yüksek elementel karbon içeriğine, daha düşük oksijen yüzdesine ve daha yüksek ısıl değere sahip bir yakıt elde edilmiştir. Karışıma uygulanan hidrotermal işlem, karışımın yapısal özelliklerini ve uçucu madde tipini modifiye etmiştir. Bu nedenle hidrotermal ön işlem görmüş karışımın piroliz ve yanma reaksiyonlarındaki reaktivitesi artmış, kütle kaybı hızının maksimum olduğu pik sıcaklıklar da ötelenmiştir.
