Production of High-Octane Number Gasoline from Basra Low Octane-Number Gas Condensate and Ethanol over Modified Zn/ZSM5 Zeolite Catalyst

Catalytic transformation of a low-octane number stable gas condensate to high-octane gasoline (RON: research octane number) is an economically and strategically vital process. In this research, modifying ZSM5 zeolite (80 Si/Al ratio) by impregnation with 2% Zn (Zn/ZSM5) was carried out increase the selectivity for isomerization aromatization thereby enhance number. The process conducted using 85 vol% 15 ethanol in fixed bed reactor. Zn/ZSM5 were examined pilot scale under different conditions temperature 360-420 °C LHSV1.2-2 h−1, pressure 5 bar. Catalysts characterized before after loading Fourier Transform Infra Red (FT-IR), Brunauer-Emmett-Teller (BET), X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Field Emission (FESEM), Transmission (TEM), N2-adsorption. SEM, FESEM, TEM have shown that no change morphology metal distribution. XRD FTIR characterizations revealed modified catalysts retained their crystallinity while N2-adsorption isotherm demonstrates significant porosity. results display optimum result at 420 °C, 1.2 bar enhancement RON from 60.5 89 whereas shows 82. Post loading, PONA test has iso-paraffin 45.4 47.4%, aromatics 10.8 14. findings translate effectiveness on – transformation. Copyright © 2023 Authors, Published BCREC Group.
