CSIC-ICP researcher Dalia Liuzzi visiting ECN for investigation on sorbent regeneration

Ongoing tests are helping finding better operating conditions for the SEDMES process, involving optimal functioning of both the catalyst and the adsorbent. More recently, cooperation between CISC-ICP and ECN has intensified with the starting of advanced SEDMES testing with CSIC synthesised catalyst materials at ECN laboratories. The picture shows CSIC-ICP researcher Dalia Liuzzi (right) and ECN researcher Özlem Pirgon (left) in ECN’s chemical lab, preparing samples for parallel testing of sorption-enhanced reactions.

Different regeneration conditions has been tested in sorption-enhanced DME synthesis (SEDMES), to assess the effect on the catalyst and the sorbent performance. It was shown that regeneration by temperature swing up to 400 °C improves the DME yield both pre- and post-water breakthrough. The adsorbent capacity clearly increases with temperature swing to 400 °C and indications are that the temperature swing also improves the catalyst activity or the adsorbent slip level.
