| Description | Zirconia has advantageous thermal stability and acid–base properties. The acidity character of $ZrO_{2}$ can be enhanced through the sulfation process forming sulfated zirconia $(ZrO_{2}-SO_{4}$). An acidity test of the catalyst produced proved that the sulfate loading s쳮ded in increasing the acidity of $ZrO_{2}$ as confirmed by the presence of characteristic absorptions of the sulfate group from the FTIR spectra of the catalyst. The $ZrO_{2}-SO_{4}$ catalyst can be further modified with transition metals, such as Platinum (Pt), Chromium (Cr), and Nickel (Ni) to increase catalytic activity and catalyst stability. It was observed that variations in the concentrations of Pt, Cr, and Ni produced a strong influence on the catalytic activity as the acidity and porosity of the catalyst increased with their addition. The activity, selectivity, and catalytic stability tests of $Pt/ZrO_{2}-SO_{4}$, $Cr/ZrO_{2}-SO_{4}$ and $Ni/ZrO_{2}-SO_{4}$ were carried out with their application in the hydrocracking reaction to produce liquid fuel. The percentage of liquid fractions produced using these catalysts were higher than the fraction produced using pure $ZrO_{2}$ and $ZrO_{2}-SO_{4}$ catalyst. |
