The increased interest in the Integrated Gasification-Combined Cycle (IGCC) power generation technology has led to a need to predict viscosities for coal ash and fluxed coal ash slags at the tapping temperatures of entrained flow gasifiers. Slags der

One of the alternate processes presently being investigated to produce electrical power from coal is Integrated Gasification Combined Cycle (IGCC). The ash, which remains when the coal is gasified in this process, is removed by tapping the molten ash

This paper presents a phase diagram approach to predict the melting temperatures of coal ash/flux mixtures and the viscosity versus temperature characteristics of the molten slags. This is illustrated by calcium oxide fluxing studies of three Austral

Dehydroxylation of kaolinite and smectite is significant in oil shale processing. The possibility of shifting these endothermic reactions from the retort to the combustor by increasing the water vapour pressure was confirmed and the kinetics of dehyd

The evaluation of kinetic parameters from thermogravimetric curves is considered for two linear transformations of the rate expression for various decomposition models. The differentials are calculated by applying splines to theoretically calculated
