Correlation of stability/rheology relationship with coal properties and chemical additives: Quarterly progress report, September 15, 1988--December 15, 1988

Abstract

In an effort to establish a criteria for designing and preparing coal-water slurry (CWS) for utilization, the relationships between coal properties and slurry quality must be determined. These relationships will enable the prediction of potential CWS quality for the particular coal candidate from some characteristic(s) of the coal. The coal content at a given viscosity varies for different coal. Thus, to develop a viable coal selection strategy using chemical surfactants as additives, the adsorption of these surfactants by the coal particle surface must be established. This work therefore, intends to screen a number of chemical surfactants and dispersants which can be used in the preparation of coal water slurry. The information derived from this screening together with the coal properties will be used to help develop a prescription to predict the stability of coal slurries. 7 refs., 1 fig., 3 tabs.
