Abstract

Slurries made from petroleum coke (petcoke) particles in water have the potential be a useful energy source. We studied the interactions between various additives and the petcoke and the effects on the slurry rheology. Adsorption and rheology studies with polyvinylalcohol, a partially hydrophilic polymer, showed that the polymer reduced viscosity only when adsorbed to the petcoke surface. Adding xanthan gum causes shear-thinning behavior, which increases storage stability, so the combination of these two additives may yield optimal slurry characteristics.
