| Summary: | <p dir="ltr">In this work we present a simple, yet powerful, metric for estimating the potential of a CCU reaction pathway to fix CO<sub>2</sub>. The CO2Fix metric is determined by using a model that accounts for various process variables and parameters that influence the ability of the reaction to convert CO<sub>2</sub> in addition to its propensity to produce CO<sub>2</sub> through the energy requirements of the process. The CO2Fix metric in this work accounts only for the direct CO<sub>2</sub> emissions and indirect CO<sub>2</sub> emissions related to the reaction portion of a CCU process. We demonstrate the use of the model to estimate the CO2Fix in two case studies representing common CCU reactions: dry reforming of methane (DRM) and CO<sub>2</sub> hydrogenation to methanol. When using natural gas-powered energy, and under the same process assumptions, the CO2Fix was estimated to be 1.1 and 3.9 for the DRM and CO<sub>2</sub> hydrogenation reactions respectively.</p><h2>Other Information</h2><p dir="ltr">Published in: Computers & Chemical Engineering<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.compchemeng.2023.108398" target="_blank">https://dx.doi.org/10.1016/j.compchemeng.2023.108398</a></p> |
