abstract = "A chemical plant layout for the production of syngas from renewable power,
H<sub>2</sub>O and biogas, is presented to ensure a steady productivity of syngas with a
constant H<sub>2</sub>-to-CO ratio under time-dependent electricity provision. An
electrolyzer supplies H<sub>2</sub> to the reverse water-gas shift reactor. The system
compensates for a drop in electricity supply by gradually operating a tri-reforming reactor, fed
with pure O<sub>2</sub> directly from the electrolyzer or from an intermediate generic
buffering device. After the introduction of modeling assumptions and governing equations, suitable
reactor parameters are identified. Finally, two optimal control problems are investigated, where
computationally expensive model evaluations are lifted
via<monospace>parareal</monospace> and necessary objective derivatives are calculated
via the continuous adjoint method. For the first time, modeling, simulation, and optimal control are
applied to a combination of the reverse water-gas shift and tri-reforming reactor, exploring a
promising pathway in the conversion of renewable power into chemicals.",
