The ESI Figures show we would like to apply higher desorption temperatures in our processes than current adsorbent stability limits allow in order to improve productivity and decrease energy consumption. If we increase the desorption temperature, we will likely reach an optimum when considering the trade-off between productivity and energy consumption. However, currently, optimisation efforts converge onto the upper bound of temperature (~100°C). Some background on amine-functionalised adsorbent stability is available in the ESI Section 2.3. Based on this, primary amine-grafted adsorbents appear to be the most promising route to preventing thermal and oxidative degradation and accessing higher desorption temperatures.
