At ECN the revamped valvebox has been hoisted on the multicolumn test rig under H2020 FLEDGED and FReSMe Projects. The test rig will be used for testing Sorption-Enhanced DME Synthesis (SEDMES) performances. Different sorbent/catalyst mixures with commercial catalyst are subjected to cycling testing in a high throughput “Spider” rig, aiming at assessign steam capacity, steam slip level, adsorption and desorption kinetics selectivity and stability. Selected mixtures will be then tested in single- and multiple-column PSA test-rig.

At ECN, Raghu Sumbharaju and Jasper van Kampen are extending the sorbent testing programme to include dedicated desorption experiments. Screening tests of different commercial steam sorbents are carried out at ECN to identifiy the most suitable sorbents for operation at SEDMES process. Different sorbent/catalyst mixures with commercial catalyst are subjected to cycling testing in a high throughput "Spider" rig, aiming at assessign steam capacity, steam slip level, adsorption and desorption kinetics selectivity and stability. Selected mixtures will be then tested in single- and multiple-column PSA test-rig. Read more on ECN website

The performance of up to six different biomasses in sorption enhanced gasification (SEG) conditions is being studied in the Bubbling Fluidized Bed (BFB) facility installed at ICB-CSIC facilities. This reactor operates in batch mode and it is electrically heated, being able to treat between 3 kg/h and 30 kg/h of biomass, which corresponds to a thermal input of 10-170 kWth (LHV-based) depending of the biomass used. Different gasification temperatures, steam flowrate and sorbent to biomass ratios are going to be tested in this facility, which will provide valuable information for the tests at a higher scale performed in FLEDGED.

FLEDGED project coordinator Matteo Romano released an interview to the Italian radio "Radio24", on the radio programme "Smart cities" about innovation. DME from biomass is one of the promising pathways towards sustainable mobility in Europe and the coordinator presented the strenghts of FLEDGED project towards an efficient and low-emission DME production process. The full interview can be found here in Italian language.

ECN presented at 5th International Conference on Tailor-Made Fuels from Biomass (20-22 June 2017, Aachen, Germany). Download the abstract here and the presentation here. A novel sorption enhanced dimethyl ether synthesis (SEDMES) process is presented using a solid adsorbent to remove produced water in situ. SEDMES experiments from feed mixtures of H2, CO, and CO2 have shown an increased yield of DME, an improved selectivity to DME over methanol, and a strongly reduced CO2 content in the product. Consequently, SEDMES will reduce the downstream separation effort and minimise the recycle streams. Within the European Horizon 2020 project FLEDGED, synthesis gas

Two contributions about FLEDGED process have been presented at the 12th International Conference on Fluidized Bed Technology (23-27 May 2017, Krakow, Poland). Presentations available in the download section (here and here). Selina Hafner from Universität Stuttgart presented a work on the production of tailored syngas for DME synthesis by sorption enhanced gasification, while Kari Myöhänen from Lappeenranta University of Technology (LUT) presented a work about the 3D-modelling of the governing phenomena inside the indirect gasifier.

INERIS presented a work titled "Promoting safety in innovative and sustainable biomass value chains" at International Symposium on Green Chemistry 2017 (16-19 May 2017, La Rochelle, France). Key issues that needs to be considered towards proactive material hazard characterization or process safety in the sector of biomass have been evidenced, with reference to FLEDGED and other ongoing projects.
