Hydroisomerization is a substantial process applied in the refinery. Straight chains are converted into branched chains upgrading the octane number with the same number of carbons. In the present research, Al-Dura Refinery supplied Iraqi light naphtha, used in a hydroisomerization process to examine the effect of locally prepared Pt/HY catalyst on process efficiency. The catalyst’s morphology and average crystallite size were measured by Scanning electron microscopy (SEM). Each experiment was carried out with a constant H2/HC mole ratio of 4 at atmospheric pressure and reaction temperatures of 230, 250, 270, 290, and 310°C, and weight hour space velocity (WHSV) of 1.5, 3, and 4.5 h–1. Gas chromatography (GC) type was used to evaluate the product quality. The findings demonstrated that the conversion of the main light naphtha compositions, 2-methylpentane (2MP), n-pentane, and 3-methylpentane (3MP), n-hexane, increased with reaction temperature. The results also showed that 270°C is the optimal operating temperature for hydroisomerization, exhibiting good isomerization selectivity.
