Deliverable 2.1 - Characterisation of raw materials for sorption enhanced gasification
This document describes the analytical techniques that were used and will be used along the project to perform the characterization of the different raw materials to be used in the gasification process. It includes the description of the techniques used for the characterization of fuels and those necessary to perform the characterization of sorbents. In addition, the full characterization of fuels and sorbents to be used in the project are also reported. It is concluded that the selected fuels can be processed in the available experimental rigs although some difference have been found between the natural biomass fuels and ECOH biomass. Regarding to the sorbents, their behavior has been similar to data found in the literature.
Deliverable 2.6 - Catalytic performance of novel catalyst mixtures for the direct synthesis of DME
This deliverable reports the results of obtained in our study to identify the optimum catalysts mixture for the direct synthesis of DME (dimethyl ether) from syngas. Two kind of acid catalysts for the DME production from methanol were tested, the commercial catalyst γ-Al2O3 and the supported heteropolyacid HWSi/TiO2 (HPA). For the methanol synthesis from syngas we used a Cu-based commercial KATALCOTM51-8 (referred to as CZA_com). Both catalysts were mixed in m:a (metallic:acid) ratios of 10:90, 50:50 ad 90:10. The DME production from syngas was tested in a fixed bed reactor at 270 ºC, 25-50 bar, 5000-7500 h-1 for the mix with γ-Al2O3 and 7500-15000 1/h for the mix with HPA. The mixture containing HPA was also tested at 240 ºC. Syngas CO2/CO-ratio= 1.9 with M=2 was used.
Deliverable 3.1 - Experimental matrix for SEG and SEDMES tests
In this report, the experimental matrices for SEG and SEDMES tests are presented, determined based on the experience gained on the SEG and SEDMES process at the current stage of the project.
The range of operating conditions defined in the experimental matrices are summarized for SEG and SEDMES processes respectively. The measurements to be carried out in the experimental campaigns are also indicated. The main measurements include gas composition and product yield, solids composition and characterization which will used for defining and validating the FLEDGED process models.
Deliverable 4.1 - Preliminary process simulations
An Aspen Plus model of the reference FLEDGED plant has been developed and used to calculate the mass and energy balance of the plant. Sensitivity analyses on the S/C in the gasifier and on the DME yield in the SEDMES process have been carried out.
Global biomass to DME conversion efficiency (Cold gas efficiency – CGE) of 38-45%LHV combined to biomass to electricity efficiency of 8-11% have been calculated. Resulting “equivalent” CGE (i.e. CGE taking into account the primary energy savings associated to electricity export) of 56-64% have been obtained. Overall results obtained are in line with those reported in the literature for other biomass to DME processes based on air-blown gasification systems. From the economic analysis of a 100 MWLHV biomass input plant, a DME cost of 49.6 €/GJLHV has been calculated, largely associated to the cost of biomass (unit cost of 125 €/t) and from the plant cost (216 M€). From the preliminary techno-economic study presented in this deliverable, suggestions for improving both conversion efficiency and economic performance are proposed.
Deliverable 6.1 - Goal and scope of the Sustainability and Process Safety analysis
WP6 deals with risk and sustainability analysis addressing impacts like environmental LCA, safety assessment, appraisal of social issues and air quality in the FLEDGED project. The present deliverable D6.1 defines the goal and scope of the sustainability and process safety analysis of the FLEDGED value chains. It also provides key information necessary for carrying out the task like the organisation, management of WP through working group, boundaries of systems to be studied, functional units, reference technologies for comparison and data framework. WP6 is an interactive and cross cutting WP needing information from all the other WPs. The information may vary from test results on materials, process simulation results, economic analysis, optimization of processes, etc.
The main outputs from this deliverable are (i) the goal and scope, boundaries, reference technologies, functional units along with the data collection framework, (ii) the establishment of working group for effective interaction with other WPs, (iii) preliminary data requirements for the different impact assessments.
