Results (slag formation versus AFT) IDT=1300 o C IDT=1311 o C IDT=1321 o C FT=1346 o C copyright reserved 2008, Sasol Technology, R&D, IP Approval PP000489
Conclusions Between 1000-1250oC the mineral composition is a mixture of both slag-liquid and crystalline material Urbain model with ash composition input assumed the system as 100% molten Viscosity predictions within fixed bed gasification conditions thus not accurate by only using the Urbain model predictions Viscosity predictions on the slag composition based on Factsage results supply a more accurate prediction of the actual molten material Correlations between trends in slag formation based on Factsage and viscosity trends on the slag composition can be explained Na 2 O plays a role in slag formation at lower temperatures and CaO at higher temperatures copyright reserved 2008, Sasol Technology, R&D, IP Approval PP000489
