Removal of sulfur ions from crude oil using copper Oxide Nanoparticles

Abstract

The present study was designed to investigate the effectiveness of the adsorption desulfurization of crude oil using CuO-NPs. The prepared of nanoparticles using a sol-gel method was subjected to a novel analysis comprising standard analytical methods, including XRD, FESEM, and EDX, to identify the crystalline phase, morphological, and referring contained of the element in the particles. Hence, the XRD of crystalline planes of CuO exhibited peaks of the monoclinic structure at 31.6°, 45.4°, 56.4°, 66.3, and 75.2° corresponding to indexed planes of 110, 112, 202, 220, and 004, respectively. The average size of CuO-NPs was found to be 34 nm based on the Debye-Scherrer equation. Comparatively, the FESEM demonstrated through agglomerated spherical shape is shown at different magnifications. The particle size was found to follow an interval ranging from 42.43 to 87.09 nm. The elemental composition of EDX profiles was composed of Cu standing at 80.6%, O at 13.9 %, and 5.5 C%. The peak of Cu along with O shows sound evidence, suggesting that it contains nanocrystals made up of CuO nanoparticles at 1:1. In summary, the lowest removal efficiency was found at the highest temperature of 328K, 150 minutes of time, and 50 mg of adsorbent, while the removal efficiency increased as the temperature fell, the adsorbent was increased, and the contact time increased. Thus, the scavenged material was providing effective removal with optimal results and possibilities to develop for industrial applicability.
