description <p dir="ltr">The hydrogenation of CO<sub>2</sub> to methanol is one of the promising CO<sub>2</sub> utilization routes in the industry that can contribute to emissions mitigation. In this work, improved operating conditions were reported for the sustainable catalytic hydrogenation of CO<sub>2</sub> to methanol using Cu/ZnO/Al<sub>2</sub>O<sub>3</sub> catalyst operated at 70 bar and 210 °C. The CO<sub>2</sub> feedstock used for this process is pure CO<sub>2</sub> produced from the cryogenic upgrading process of biogas or hydrocarbon industries and ready-to-use hydrogen purchased at 30 bar and 25 °C. The process was modeled and simulated using the commercial Aspen Plus software to produce methanol with a purity greater than 99% at 1 bar and 25 °C. The simulation results revealed that an adiabatic reactor operated with a CO<sub>2</sub>/H<sub>2</sub> ratio of 1:7 produces methanol with a yield ≥99.84% and a CO<sub>2</sub> conversion of 95.66%. Optimizing the heat exchanger network (HEN) achieved energy savings of 63% and reduced total direct and indirect CO<sub>2</sub> emissions by 97.8%. The proposed methanol process with an annual production rate of 2.34 kt/yr is economically sound with a payback period of nine years if the maximum H<sub>2</sub> price remains below $0.97/kg. Hence, producing or purchasing gray H<sub>2</sub> from a steam reforming plant is the most viable economic source for the process.</p><h2>Other Information</h2><p dir="ltr">Published in: Fuel<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.fuel.2022.126027" target="_blank">https://dx.doi.org/10.1016/j.fuel.2022.126027</a></p>
