Abstract

The properties of biochar, which are very important in the last decade, are critical in determining usage purpose and estimating potential functions in the soil environment. In this study, some physico-chemical properties of biochar, obtained from slow pyrolysis process at 400 ℃ from rice straw, were investigated by means of advanced analytical techniques. In the study, the properties of biochar material such as yield, volatile matter (VM), mineral ash content (MAC), fixed carbon (FC), elemental composition (C, H, N, S), spectroscopic properties (FT-IR, 13C NMR, XPS, XRF and XRD), morphological attributes (SEM-EDX), particle size and specific surface area were investigated. According to the results biochar produced from rice straw at 400 °C has large pores and moderate to low specific surface area; is a weakly crystalline, carbon-rich cellulosic amorphous material; contains silvite (KCl) mineral. These properties show that biochar may be suitable for use in carbon stabilization in soils.

Özet

Son yıllarda oldukça güncel olan biyokömürün özellikleri, kullanım alanının belirlenmesi ve toprak ortamındaki potansiyel fonksiyonlarının tahmininde kritik öneme sahiptir. Bu çalışmada çeltik saplarından 400℃’de yavaş piroliz yoluyla elde edilen biyokömürün bazı fizikokimyasal özellikleri ileri analitik tekniklerle incelenmiştir. Çalışmada, elde edilen biyokömür materyalinde; verim, uçucu madde (UM) mineral kül içeriği (MKİ), sabit karbon (SK), elementel analizler (C, H, N, S), spektroskopik analizler (FT-IR, 13C NMR, XPS, XRF ve XRD), görüntüleme analizi (SEM-EDX), parçacık boyutu ve spesifik yüzey alanı analizleri yapılmıştır. Elde edilen bu sonuçlara göre, 400 °C'de pirinç sap/samanından üretilen biyokömür, büyük gözeneklere ve orta ila düşük özgül yüzey alanına sahiptir; zayıf kristalik, karbonca zengin, selülozik amorf bir malzemedir ve silvit (KCl) mineralini içermektedir. Bu özellikleri biyokömürün topraklarda karbon stabilizasyonunda kullanımına uygun olabileceğini göstermektedir.
