Tailoring the Reactor Properties in the Small‐Scale Sorption‐Enhanced Methanol Synthesis
Emanuele Moioli, Tilman J. Schildhauer
Abstract
Abstract The performance of a fixed‐bed and entrained flow reactor for the sorption‐enhanced methanol synthesis from CO 2 is assessed by modelling. Both reactors achieve good performance but show possible drawbacks. The fixed bed reactor requires several units working in parallel, while the entrained flow reactor needs a large volume due to the high superficial particle velocity. We propose a new reactor type, which combines a circulating sorbent with a fluidized bed methanol catalyst in bubbling regime. This solution achieves high CO 2 conversion with high space velocity in a continuous manner.
