Abstract: An organometallic chemistry-based compound for preventing coke formation in a hydrocarbon fluid system. The organometallic chemistry-based compound includes a coordination complex that interrupts an autoxidative pathway of coke formation. A component and a system for mitigating coke formation during delivery or circulation of a hydrocarbon fluid. The component includes a contact surface configured to be in contact with the hydrocarbon fluid. The contact surface is functionalized with an inhibitor ligand to form an inhibitor ligand-functionalized surface. The inhibitor ligand-functionalized surface interrupts an autoxidative pathway of coke formation.

Abstract: A component configured to be in contact with a hydrocarbon fluid and a method of preparing a contact surface of the component. The component may include a wall having the contact surface configured to be in contact with the hydrocarbon fluid. The contact surface is formed from a metal comprising a metal M, where M is selected from the group consisting of nickel (Ni), palladium (Pd), and platinum (Pt). A metal-ligand complex comprising phosphorus (P) is on the contact surface. The method of preparing a contact surface of the component may include treating the contact surface with a metal-ligand complex precursor comprising a phosphorus (P) ligand.

Abstract: A component and a system for mitigating coke formation during delivery of a hydrocarbon fluid. The component includes a contact surface configured to be in contact with the hydrocarbon fluid. Tuning the zeta potential of the contact surface allows selective attraction and/or repulsion of coke-catalyzing materials, metal ions, heteroatomic hydrocarbons, and/or coke precursors present in the hydrocarbon fluid. A method of mitigating coke formation during delivery of a hydrocarbon fluid includes tuning a zeta potential of the contact surface of the component and injecting or circulating the hydrocarbon fluid through the system such that the contact surface selectively attracts and/or repels coke-catalyzing materials, metal ions, heteroatomic hydrocarbons, and/or coke precursors present in the hydrocarbon fluid.
