N2 - The performance of a fatty acid amide inhibitor synthesized from the coffee bagasse oil has been evaluated by electrochemical techniques such as potentiodynamic polarization curves, open circuit potential measurements, linear polarization resistance, and electrochemical impedance spectroscopy. Inhibitor concentrations included 0, 5, 10, 25, 50, and 100 ppm. Inhibitor efficiency was evaluated on an X70 steel in a CO 2 -saturated brine at 60°C. All the different techniques have indicated a decrease in the cathodic current density and inhibitor efficiency values as high as 96%. The inhibitor was chemically adsorbed on to the steel according to the analysis of the inhibitor adsorption process.
