2019 - ICPS 19 - International Conference on Polygeneration Strategies
<a href = '/wp-content/uploads/Downloads/Presentations/Conferences/FLEDGED_201911_ICPS19_SHafner_presentation.pdf'>Download presentation on syngas production for DME synthesis from Sorption Enhanced Gasification of Biomass: A Pilot Plant-based Case Study (USTUTT - Hafner)</a>
The presentation covers results achieved from SEG with wood pellets and pellets made out of the organic fraction of municipal solid waste. Results are presented comprehensively focusing on syngas composition, considering standard gases (H2, CO, CO2 and CH4), lower hydrocarbons (C2-C4) and tars. It is shown that the facility can be operated stably with both investigated fuels and that both fuels are suitable for the production of a syngas with a Module M equal to 2 that is required for downstream DME synthesis.

2019 - ORC 2019 - 5th International Seminar on ORC Power Systems
<a href = '/wp-content/uploads/Downloads/Presentations/Conferences/FLEDGED_201909_ORC2019_CElsido_ORCrecovery_presentation.pdf'>Download poster on design optimization of a heat recovery ORC for a novel biomass to methanol plant (POLIMI - Elsido)</a>
This work presents the optimization of ORCs for recovering waste heat from a novel process for the co-production of methanol and electricity from biomass. The process uses a flexible sorption enhanced gasification reactor, developed in the framework of the H2020 EU project FLEDGED. The heat integration study is particularly interesting because the process features multiple hot and cold streams at different temperatures (i.e., the calciner flue gases, the syngas coolers, etc.) making it necessary to optimize not only the ORC configuration (i.e., single vs. multiple pressure levels, regenerative vs. simple cycle, combined heat and power arrangement, etc.) but also the heat exchanger network.
For two candidate working fluids, hexane and R1233zde, the cycle and heat integration are optimized using the p-h ORC superstructure and a systematic synthesis methodology recently proposed by Martelli et al. (2017). The optimization aims at maximizing the economic performance of the system taking into account the trade-off between efficiency and costs.

2019 - Conference of the Spanish Society of Catalysis - SECAT
<a href = '/wp-content/uploads/Downloads/Presentations/Conferences/FLEDGED_201906_SECAT2019_DLiuzzi_presentation.pdf'>Download presentation about double bed configurations for methanol synthesis from CO2-rich bio-syngas (ICP-CSIC - Peinado - in Spanish)</a>
The production of biofuels such as methanol and DME from bio-syngas is a topic of great interest. The production of methanol from syngas derived from natural has been studied extensively, using Cu/ZnO/Al2O3 (CZA) catalysts as benchmark. In this work, the effect of reducing the CO2 content of the bio-syngas through the reverse water gas shift (R-WGS) reaction before the methanol synthesis has been studied. In order to that, the possibility of using a double catalytic bed, using a RWGS catalyst as the upper bed and a CZA catalysts for the methanol synthesis as the lower bed has been studied. Our results indicate that in order to obtain higher methanol productivities, the H2O produced during the RWGS has to be removed before the CO2-lean bio-syngas reaches the CZA catalytic bed.

<a href = '/wp-content/uploads/Downloads/Presentations/Conferences/FLEDGED_201810_GHGT14_Martinez_DMEandSNGfromSEG.pdf'>Download presentation Sorption enhanced gasification (SEG) of biomass with CO2 capture for the production of Synthetic Natural Gas (SNG) and DME for transport sector with negative emissions (CSIC - Martinez)</a>
Presentation on a process assessment of two synthetic fuel production plants based on a flexible Sorption Enhanced Gasification (SEG) of biomass is carried out, one focused on Synthetic Natural Gas (SNG) and the other on dimethyl ether (DME) production. Mass and energy balances of these two synthetic fuel production plants have been solved and their performance has been compared. The calculated biomass-to-fuel equivalent cold gas efficiency CGEeq (i.e. accounting for energy credits/debits associated to electricity export/import) ranges from 53.7% of the bio-SNG plant to 51.3% of the bio-DME plant. The assessed plants are also able to capture 63-67% of the inlet biomass carbon, leading to negative Well-to-Wheel emissions (around -160 g/km). The WTW CO2 emission saving in comparison with a conventional diesel vehicle is then around 260 g/km.
2018 - SDEWES2018 - Conference on Sustainable Development of Energy, Water and Environment System
<a href = '/wp-content/uploads/Downloads/Presentations/Conferences/FLEDGED_201809_SDEWES2018_CElsido_presentation.pdf'>Download presentation Preliminary simulation study and heat integration of a highly intensified and flexible process for bio-DME and electricity production (POLIMI - Elsido)</a>
Presentation on the preliminary process modelling study and heat integration optimization for a novel highly intensified and flexible process for the co-production of bio-DME and electricity from biomass. The process combines two “sorption-enhanced” reactors: a flexible sorption enhanced gasification and a novel sorption enhanced DME synthesis. The novel system is being developed in the framework of the H2020 EU project FLEDGED. The preliminary process simulation is based on simplified (first-principle) models of the main process units while the heat integration optimization is performed with a systematic energy targeting methodology. The DME off-gas can be used in a gas turbine or in an internal combustion engine with minor differences in efficiency while the process waste heat can be efficiently recovered by a multiple-pressure-level heat recovery steam cycle. According to the results, the plant can achieve a biomass-to-DME conversion efficiency of 31.14 % (LHV basis) and a biomass-to-electricity conversion efficiency of 19.3 %.
2018 - ECCRIA 12 - 12th European Conference on Fuel and Energy Research and its Applications
<a href = '/wp-content/uploads/Downloads/Presentations/Conferences/FLEDGED_201809_ECCRIA_IMartinez_presentation.pdf'>Download presentation <i>Experimental investigation on sorption enhanced gasification (SEG) of biomass in a fluidized bed reactor for producing a tailored syngas</i> (CSIC - Martinez)</a>
Presentation on the analysis of the effect of different operating parameters (e.g. steam-to-carbon (S/C) ratio, CO2 sorption capacity and sorbent-to-biomass ratio) in the syngas composition and char conversion obtained in a 20-30 kWth bubbling fluidized bed gasifier, using grape seeds as feedstock. The importance of reducing the formation of higher hydrocarbons through a higher steam-to-carbon ratio and using a CO2 sorbent with high sorption capacity is assessed. C2+ concentrations below 0.6%vol. (in dry basis) can be achieved when working with S/C ratios of 1.5 at gasification temperatures from 700 to 740ºC. Varying the amount of the CO2 separated in the gasifier (by modifying the temperature or the CO2 sorption capacity of the sorbent) the content of H2, CO and CO2 in the syngas produced can be greatly modified, resulting in a module M=(H2-CO2)/(CO+CO2) that ranges from 1.2 to almost 3.

The interaction of water with alumina provides understanding of the impact of the regeneration temperature on the catalyst activity.
