Experiments using different gasification temperatures, sorbent-to-biomass and steam-to-carbon ratios have been conducted, which allowed assessing the influence of each operating variable independently. Gas yield has been found to be mainly linked with the char conversion reached in the reactor, which is influenced by the temperature, the solid residence time and the type of biomass. No significant effect of the steam-to-carbon ratio has been found in the content of H<sub>2<\/sub>, CO, CO<sub>2<\/sub> and CH<sub>4<\/sub> in the syngas (and so on the M-module) when keeping the temperature and the sorbent-to-biomass ratio constant. The M-module is driven by the gasification temperature and the sorbent-to-biomass ratio by means of the CO<sub>2<\/sub> separated from the gas phase, and the optimum value for DME production (M=2) has been reached for most of the biomass tested. The biogenic waste material from the Econward plant resulted to be among the most reactive feedstocks tested, resulting in the largest gas yields (i.e. up to 1.6 Nm<sup>3<\/sup>\/kg<sub>waf<\/sub> biomass). However, in a temperature range of 650-680\u00baC this waste biomass could lead to the largest tar yields compared to other biomasses (see the figure). The combustion of the unconverted char coupled to the calcination of the carbonated sorbent has been also studied in the BFB facility at ICB-CSIC. <\/p>\n\n\n\n<p>Experiments using different char\/sorbent ratios, air excess amounts and temperatures have been conducted for chars coming from two different biomass feedstocks. Combustion and calcination efficiencies higher than 98 % and 94 %, respectively, have been reached when operating the reactor at 860\u00b0C, being the formation of polycyclic aromatic hydrocarbons (PAHs) being the main issue to be solved.

The feasibility of reactive steam adsorption processes, such as sorption-enhanced DME synthesis (SEDMES) require high working capacity, heat management as is currently being addressed in the FLEDGED project. Finally, it became clear how progress in process development requires combination of theory and experiments.  Preliminary testing (TRL3) in the laboratory at ECN.TNO has led to a  dataset (&gt;300 SEDMES runs) of performance, in terms of DME yield and  DME productivity, as a function of operating parameters.  The potential operating window has been defined and a suitable  combination of catalyst for direct DME synthesis and zeolite water  adsorbent.

The dataset that was obtained in the TRL3 testing is currently being used to validate the SEDMES reactor models at ECN.TNO as well as at POLIMI. To further intensify cooperation, POLIMI PhD candidate Simone Guffanti has moved to ECN.TNO in Petten for the first half of 2019, where he focuses on aligning the heat balance modelling with bench-scale experiments as well as intra-particle mass transfer phenomena. Currently, the modelling efforts at ECN.TNO are directed towards optimising the SEDMES cycle design in terms of DME productivity.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_ECNfacilities.png\" alt=\"\" class=\"wp-image-1575\" width=\"432\" height=\"257\" srcset=\"https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_ECNfacilities.png 575w, https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_ECNfacilities-300x178.png 300w\" sizes=\"auto, (max-width: 432px) 100vw, 432px\" \/><figcaption> <em>ECN.TNO bench-scale test facility (TRL4) for SEDMES<\/em>  (left) and <em>lab-scale test facility (TRL3) for sorption-enhanced DME synthesis<\/em>  (right). <\/figcaption><\/figure><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Catalyst development at CSIC-ICP<\/strong><\/h3>\n\n\n\n<p>The\nCSIC Institute of Catalysis and Petrochemistry, developed two series of\ncatalysts: one series for the methanol synthesis from bio-syngas and one for\nDME synthesis from methanol dehydration.

The conventional multitubular reactor behavior has been described using a heterogeneous steady state single-tube model.   Governing equations consist of  i-species mass, energy and momentum balances of the fluid phase written in 2D cylindrical coordinates, coupled with  i-species mass and energy balances for the catalyst phase accounting for concentration gradients (1D) in an isothermal catalyst pellet. This model has been used as a tool for an extensive parametric analysis aimed to identify the best operating conditions (temperature, pressure, space velocity and composition) and to design the reactor (tube diameter and length) in order to maximize the DME productivity and controlling the temperature hot-spot. The analysis includes also a detailed study of the possible different configurations (hybrid, mechanical mixture, core@shell) of the two catalysts present in the DME direct synthesis process (methanol synthesis and methanol dehydration catalyst). The 2D dynamic SEDMES reactor model has also been developed and implemented in gPROMS and it is now ready&nbsp; to make predictions on the reaction\/adsorption behavior of the process. For this purpose, the POLIMI PhD candidate Simone Guffanti moved to ECN.TNO for a six months internship. The focus of the cooperation is the SEDMES model assessment achieved through an experiment\/model comparison and the analysis of the mass and heat exchange phenomena inside the bench-scale reactor. The assessed SEDMES model will be used for the rational design of the SEDMES reactor and comparison of the performances with those obtained with the conventional reactor model.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_LCCPmodels.png\" alt=\"\" class=\"wp-image-1579\" width=\"400\" height=\"261\" srcset=\"https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_LCCPmodels.png 652w, https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_LCCPmodels-300x196.png 300w, https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_LCCPmodels-594x389.png 594w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><figcaption>  <em>Comparison of the conventional and sorption-enhanced DME synthesis reactor models and examples of estimated temperature profiles.<\/em> <\/figcaption><\/figure><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Preliminary techno-economic analysis of the complete FLEDGED plant released by POLIMI<\/strong><\/h3>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_POLIMIlayout.png\" alt=\"\" class=\"wp-image-1571\" width=\"385\" height=\"315\" srcset=\"https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_POLIMIlayout.png 591w, https:\/\/www.fledged.eu\/wp-content\/uploads\/N4_POLIMIlayout-300x246.png 300w\" sizes=\"auto, (max-width: 385px) 100vw, 385px\" \/><figcaption>  <em>Reference FLEDGED plant configuration.<\/em> <\/figcaption><\/figure><\/div>\n\n\n\n<p>POLIMI\ndeveloped an Aspen Plus model to calculate the heat and mass balances of a\nreference complete FLEDGED plant, including: i) a biomass drying and\npreparation unit, ii) the SEG process, iii) the syngas cleaning units for the\nremoval of tar (OLGA), soluble contaminants (water scrubber), bulk sulfur\nremoval (liquid redox process) and residual contaminants and H<sub>2<\/sub>S (activated carbons and ZnO bed), iv) syngas compression, v) DME\nreactors and vi) DME separation unit. <\/p>\n\n\n\n<p>The model allowed calculating the key performance indicators such as the biomass-to-DME conversion efficiency and the electric efficiency.

Risk assessment carried out in the FLEDGED project aims at eliminating or minimizing identified hazards from the process rather than incorporating add-on controls and safety barriers at a later stage. A stepwise methodology is implemented to study the risks related to process steps and materials all along the value chain, making use of Inherently safer Design (ISD) approach for the safe and sustainable development and deployment of the FLEDGED technology. One of the tasks in progress is the safety characterization of the material streams for the physico-chemical properties related to hazards (e.g flammability, explosibility) and related risks (fire, explosion sensitivity, self-heating\u2026). Dedicated experiments will focus on the wood biomass, refuse derived fuels and catalysts. The risk assessment will focus on comparison of process configurations with respect to safety (e.g. hydrogen integration and storage, reforming and CCS options), identification of accident scenarios, evaluation of ATEX zones, choice of equipment, safe handling and storage of biomass and proposition of technical and organizational safety barriers. The results will contribute to the safe development and deployment of the FLEDGED technologies.  <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"988\" height=\"422\" src=\"https:\/\/www.fledged.eu\/wp-content\/uploads\/SafetyFaciliities.png\" alt=\"\" class=\"wp-image-1416\" srcset=\"https:\/\/www.fledged.eu\/wp-content\/uploads\/SafetyFaciliities.png 988w, https:\/\/www.fledged.eu\/wp-content\/uploads\/SafetyFaciliities-300x128.png 300w, https:\/\/www.fledged.eu\/wp-content\/uploads\/SafetyFaciliities-768x328.png 768w, https:\/\/www.fledged.eu\/wp-content\/uploads\/SafetyFaciliities-594x254.png 594w\" sizes=\"auto, (max-width: 988px) 100vw, 988px\" \/><figcaption>  <em>Experimental facilities for safety characterization of material streams <\/em> <\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Financial analysis for commercial exploitation of FLEDGED technology (ECONWARD, FRAMES and SUMITOMO FW)<\/h3>\n\n\n\n<p>Two exploitation business models of FLEDGED technology have been conducted to produce DME from different types of biomass. The first exploitation model proposes the use of lignin and wood biomass as raw material, while the second model proposes biomass produced from Municipal Solid Waste by ECONWARD technology as feedstock.

In this model, ECONWARD technology provides a pretreatment of MSW to recover the organic fraction and produce a homogenous and sanitized biomass. The pretreatment increases CAPEX, but it allows to valorize a waste that today ends mostly in a landfill. In a waste management perspective, the process is a cost-effective solution which provides a solution aligned with the European directives in circular economy. The obtained range of DME sales price (100 \u2013 2000 \u20ac\/ton DME) is competitive under certain values of Fledged technology CAPEX and tipping fee. It is necessary to further improve the process and technology to make the exploitation models more&nbsp; competitive and attractive.

However, the produced steam reduces the activity. In this work, the influence of the exposure of \u03b3-Al2O3 to steam on the catalytic activity for methanol dehydration has been determined. At 250\u202f\u00b0C and increasing stream partial pressure the conversion of \u03b3-Al2O3 into \u03b3-AlO(OH) is observed at a p(H2O) of 13\u201314\u202fbar. As a consequence, the catalytic activity decreases, reducing the rate of methanol dehydration to around 25%. However, this conversion is reversible and under reaction conditions \u03b3-AlO(OH) converts back to \u03b3-Al2O3, recovering its catalytic activity. <\/p>\n\n\n\n<p><strong><em><a href=\"https:\/\/zenodo.org\/record\/1999219\">Open access full paper on <\/a><\/em><\/strong><strong><em><a href=\"https:\/\/zenodo.org\/record\/1999219\">Zenodo<\/a><\/em><\/strong><\/p>\n\n\n\n<p><strong>Steam separation enhanced reactions: Review and outlook <\/strong>(van Kampen J., Boon J., van Berkel F.P.F.

However, although some advantages of reactive steam separation are readily apparent from a theoretical, thermodynamic point of view, the developments in several research lines make clear that the feasibility of in situ steam removal should be addressed case specifically and not only from a theoretical point of view. This includes the hydrothermal stability of the membranes and their permselectivity for reactive steam permeation, whereas high-temperature working capacities and heat management are crucial aspects for reactive steam adsorption. Together, these developments can accelerate further discovery, innovation and the rollout of steam separation enhanced reaction processes. <\/p>\n\n\n\n<p><strong><em><a href=\"https:\/\/zenodo.org\/record\/3248628\">Open access full paper on <\/a><\/em><\/strong><strong><em><a href=\"https:\/\/zenodo.org\/record\/3248628\">Zenodo<\/a><\/em><\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>Newsletter #4 &#8211; June 2019 Download pdf version here.
