Abstract: Polymer compositions for coating of metal surfaces including moieties that interact with a metal atom in the metal surface and optionally containing antifoulant moieties. These polymer compositions provide lubricious coatings for medical devices, anticorrosion coatings for metal components, and antifoulant coatings for marine components such as propellers. The polymer composition is synthesized in a safe manner in which the synthesis components are added to a synthesis vat and there is no need for filtration or removal of waste materials in any step including the consumer use. As such this invention provides an environmentally sound approach to composition synthesis, formulation development, and consumer use.

Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to produce less fouling sediment. The dual catalyst system more effectively converts sediment-forming precursors to produce sediment that is less fouling than sediment produced using only the heterogeneous catalyst and not the dispersed metal sulfide particles. The dual catalyst system provides for a lower rate of equipment fouling for a given sediment production rate and/or concentration. In some cases, sediment production rate and/or concentration can be maintained or increased while equipment fouling is reduced. In some cases, sediment production rate and/or concentration can be increased without increasing equipment fouling.
