Novel Multiplicity and Stability Criteria for Non-Isothermal Fixed-Bed Reactors

Autor: Jens Bremer, Kai Sundmacher

Publikováno v: Frontiers in Energy Research, Vol 8 (2021)

With the increasing need to utilize carbon dioxide, fixed-bed reactors for catalytic hydrogenation will become a decisive element for modern chemicals and energy carrier production. In this context, the resilience and flexibility to changing operatin

Non-intrusive Time-POD for Optimal Control of a Fixed-Bed Reactor for CO2 Methanation

The optimization of a controlled process in a simulation without access to the model itself is a common scenario and very relevant to many chemical engineering applications. A general approach is to apply a black-box optimization algorithm to a param

CO2 methanation is often performed on Ni/Al2O3 catalysts, which can suffer from mass transport limitations and, therefore, decreased efficiency. Here we show the application of a hierarchically porous Ni/Al2O3 catalyst for methanation of CO2. The mat
