Project goals

The project aims to develop a continuous low-temperature process for the production of methanol, which combines the normally separate process steps of CO₂ separation and CO₂ hydrogenation in one process step. This eliminates the thermal separation step to obtain the pure CO₂ from the amine wash solution and instead catalytically converts the CO₂ still bound in the amine directly to the product. So far the process has only been shown in batch processes. An important goal is the construction of a continuously working demonstrator.

Application

The process to be developed represents a new low-temperature process for methanol synthesis from CO₂, which could potentially also be suitable for large-scale production of methanol. However the process appears to be particularly advantageous for smaller plants for decentralized energy storage due to the simpler heat management in the liquid phase.
