Applications of zeolite-zirconia-copper nanocomposites as a new asphaltene inhibitor for improving permeability reduction during CO₂ flooding.

ABSTRACT: Using nanoparticles for adsorbing asphaltene was known as an efficient method among researchers for crude oil upgrading. In this study, zeolite-zirconia-copper nanocomposites (NCs) have been synthesized and characterized with Scanning electron microscopy (SEM), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), and energy-dispersive X-ray (EDX). Then, CO₂-oil interfacial tension (IFT) tests, Ultraviolet-visible spectroscopy (UV-Vis) Langmuir and Freundlich isotherm models, asphaltene precipitation tests at static phase, and dynamic CO₂ flooding tests were performed in the presence of NCs and the results were compared with zeolite nanoparticles. Based on the characterization results, zirconia-copper particles were distributed at the surface of zeolite with total di
