What is Settling Aids for Hydrocarbon Solids about?

This patent describes a method for accelerating the settling of finely divided solids in hydrocarbon fluids. Specifically, it involves adding a sufficient amount of a polyacrylic acid adducted alkylphenol-formaldehyde resin alkoxylate compound to the hydrocarbon fluid. This additive is effective at accelerating the settling of spent fluid catalytic cracking (FCC) catalyst fines in an oil slurry. A series of examples are provided to demonstrate the efficacy of this method.
