The Department of Chemistry at the College of Science, University of Mosul, discussed a Master’s thesis entitled \u201cImproving the Quality of Petroleum Products Using Nanocatalysts\u201d<\/strong> on Wednesday, 22 April 2026.<\/p>\n

The thesis, submitted by Mr. Omar Sami Hamad Sultan Al-Rawi<\/strong>, investigated, for the first time, the use of nanomaterials in upgrading and converting Qayyarah heavy crude oil, characterized by its aromatic nature, into lighter petroleum fractions such as gasoline, used as automotive fuel, and kerosene (white oil), commonly utilized for heating purposes.<\/p>\n

The study aimed to determine the optimum conditions for the thermal treatment of heavy crude oil. Two different approaches were adopted to achieve the highest conversion yield of petroleum distillates using two types of nanomaterials as catalysts: nanocarbon<\/strong> and nanosilica<\/strong>. The findings demonstrated that nanosilica achieved a higher yield of petroleum products compared with nanocarbon materials.<\/p>\n

The nanomaterials were characterized using advanced analytical techniques, including Atomic Force Microscopy (AFM), Field Emission Scanning Electron Microscopy (FESEM), Energy-Dispersive X-ray Spectroscopy (EDX), X-ray Diffraction (XRD),<\/strong> and Fourier Transform Infrared Spectroscopy (FTIR)<\/strong> to investigate their surface structures and catalytic performance.<\/p>\n

The study also included a range of physical and chemical analyses of the resulting distillates, such as density, freezing point, acid number, cetane number, API gravity, and sulfur content. The results indicated the potential preliminary use of these products as automotive fuels. These promising outcomes contribute to addressing the challenges associated with Qayyarah crude oil, particularly its high sulfur content and limited production of light fractions.<\/p>\n
