    \                   , can be a part of the transformation towards renewable energy
    carriers. A major engineering challenge is the optimization of the fixed‐bed reactor
    design, specifically the heat dissipation in regions of high reaction heat release.
    A mitigation concept is the introduction of inert material into the fixed bed,
    called catalyst dilution. In this study, a 1D continuity model is presented, which
    aims to predict catalyst superheating. This model is used in an exploratory study
    to identify system sensitivity and optimization parameters. Subsequently, an optimization
    framework for improving the reactor design is tested, resulting in a 148‐K reduction
    in peak catalyst temperature when using a 33.3 vol% catalyst dilution.\r\n                  </jats:p>"
