Öz

In this study, high sulphur (1.2%) and ash (20.6%) containing Tunçbilek lignite was co-gasified with raw sorghum (green go) biomass and sorghum hydrolysate, which was hydrolyzed under sub-critical conditions, and synergetic effects of sorghum on co-gasification process were investigated as well as product distributions. The total gas volume obtained from individual gasification of Tunçbilek lignite was less than those obtained from both co–gasification with raw Sorghum and Sorghum hydrolysate. The highest total gas (2810 mL) and hydrogen yield (70.1%) was obtained from co–gasification with sorghum hydrolysate.

Tunçbilek Linyitinin Sorgum Biyokütlesi ve Biyokütle Hidrolizatı ile Birlikte Gazlaştırılması

Öz

Bu çalışmada, yüksek oranda kükürt (%1,2) ve kül (%20,6) içeren Tunçbilek linyiti, öğütülmüş katı sorgum (green go) ve sub-kritik su koşullarında hidroliz edilmiş sorgum hidrolizatı ile birlikte gazlaştırılarak gaz ürün dağılımı ve birlikte gazlaştırma işlemine sorgumun sinerjik etkisi incelenmiştir. Öğütülmüş katı sorgum ve sorgum hidrolizatı ile yapılan birlikte gazlaştırma deneylerinden elde edilen gaz hacimleri, Tunçbilek linyitinin tek başına gazlaştırılmasından elde edilenden daha fazla olduğu görülmüştür. En yüksek toplam gaz hacmi (2810 mL) ve hidrojen verimi (%70,1) 900 °C sıcaklıkta sorgum hidrolizatı ile yapılan birlikte gazlaştırma deneylerinden elde edilmiştir.
