A major task addressed in the Strategic Energy Technology Plan of the EU is the sustainable power generation from fossil fuels. A crucial step here is the separation of CO2 from flue gas. INTERACT investigates the scientific and technological basis of radically innovative materials and processes. Strong improvement of the energy penalty of the capture process below 5 % points and reduction of the CO2 capture costs significantly below 50% by simultaneously substantially decreasing the footprint of power plants and thus the environmental impact. INTERACT follows the idea of the concurrent engineering in which new materials for CO2 capture i.e. membranes, highly efficient nanomaterials and biological absorbents are combined with innovative technologies resulting in real breakthroughs according to criteria given in Topic ENERGY 2013.5.1.2. The general concept of INTERACT is to open new pathways for development of high-potential novel processes for post combustion CO2 capture based on new materials, using poly(ionic liquid)s or enzymes, integrated into gas separation technologies such as gas separation membranes, absorption in columns and absorption using membrane contactors. Several innovative absorbents and adsorbents - the main bottleneck of the conventional processes - will be in depth analysed for applications in different unit process operations. Tests in full scale for long term operation under realistic operating conditions will confirm their feasibility. It will result of proof of concept for the most suitable combination of new material by design and innovative technology. These activities fully agree with the recommendations of the Materials Roadmaps Enabling Low Carbon Energy Technologies from 2011. The consortium composed of industry, universities and research institutes will provide the technological basis for advanced CO2 separation both for large scale operation of power stations or other energy intensive industry as well as for smaller emission sources


The invention refers to the method for the utilization of low-concentration mixtures of a combustible gas and air with the stable recovery of heat and the flow-reversal device for the embodiment of the method. The method consists in the combustion, with heat recovery, of the mixtures in the flow-reversal device having at least a single pair of combustion sections, each of which has the structural packing of monolith blocks with small channels characterized by low pressure drop, provided with an internal heating device, temperature and composition sensors and the elements of the automatic control system, supplied with the low-concentration mixture with the combustible component and connected with the heat recovery apparatus through the pipeline, wherein the quantity of energy transferred in the heat recovery apparatus (22) is stabilized by supplying additional fuel to the flow-reversal device, selecting the flow reversal moment, and selecting the flow rate for hot gas supplied by the pipeline to the heat recovery apparatus (22). Additional fuel in the form of highly concentrated fuel mixture is introduced as an admixture to the stream of low concentrated mixture containing the combustible component, supplied to the flow-reversal device or to the internal heating device (7). The device according to the invention, in its combustion sections (I, II) is provided with symmetrical temperature sensors (T_(i), T_(ii)) and an additional supply of highly concentrated combustible mixture (17) connected to the supply system for low-concentration mixture (15) with the combustible component or to the internal heating device (7). The combustion sections (I, II) are packed with heat-accumulating material (1, 2) of small porosity of the specific surface area below 30 m^(2)/g, and advantageously below 1 m^(2)/g.

The study of CO2 absorption in ionic liquids (ILs): [Emim] [Ac], [Bmim] [Ac] in a packed column is presented. The influence of mass transfer resistances, initial CO2 concentration, absorption temperature and 2, 5, 10% wt. water addition on CO2 removal efficiency was investigated. The resistance in series model and estimated values of enhancement factor were used to predict with good accuracy mass fluxes of absorbed carbon dioxide for both ILs. The CO2 absorption efficiency in packed column depends on temperature and initial CO2 concentration. The addition of small amounts of water to [Emim][Ac] is of minor effect on CO2 absorption. ©2016 Taylor & Francis

The study of CO2 absorption in ionic liquids: [Emim][Ac], [Bmim][Ac] and 15 wt.% MEA solution in a packed bed column is presented. Absorption column of inner diameter 0.05 m and 0.35 m length was filled with Raschig rings φ5 mm × 5 mm × 1 mm. Investigations were performed at atmospheric pressure what is important in the case of post combustion flue gases. The influence of mass transfer resistances in gas and liquid phase as well as initial CO2 concentration and absorption temperature on CO2 removal efficiency was investigated. In calculations the resistance in series model of the absorption process was applied. The estimated values of enhancement factor of the reaction between CO2 and investigated liquids were used to predict mass fluxes of absorbed carbon dioxide for both ILs and MEA solution. The comparison of experimental and calculation results show that in the same experimental conditions the investigated ILs and MEA solution have comparable CO2 absorption capacities. The liquid side mass transfer coefficients in the case of ILs are several times lower than for MEA solution. The research for new ILs characterized by chemisorption mechanism, low viscosity and price is needed to take advantages of applying ionic liquids in the process of CO2 separation in a packed column. © 2016 Elsevier Ltd.

The comparative study of CO2 absorption in ionic liquids: [Emim][Ac], [Bmim][Ac] and 15% MEA solution in packed bed column is presented. Investigations were performed for low pressures, what is important in the case of post combustion flue gases. Absorption column (0.3 m length, inner diameter 0.05 m) was filled with Raschig rings ω5 × 5 × 1 mm. The influence of initial CO2 concentration, absorption temperature, gas and liquid flow direction on removal efficiency was investigated. Experiments were compared with calculation based upon resistance in series model of the absorption process in packed column taking into account enhancement factor of reaction between CO2 and investigated liquids. The results show that in the same experimental conditions ILs have comparable CO2 absorption capacities with MEA solution. However ILs need much longer times to absorb the same amount of carbon dioxide from gas mixture. The research for new ILs with lower viscosity and price is needed to take advantages of ionic liquids for the process of CO2 stripping in packed column. © 2015 Elsevier B.V. All rights reserved.

Glutaric acid was esterified with BuCHEtCH2OH to resp. mono- and diesters in a lab. isothermal semibatch reactor to study the reaction kinetics. In the presence of H2SO4 catalyst, the reaction of monoester formation was 1st order reaction while the reaction of the diester formation was a 2nd order reaction. Lack of catalyst resulted in a change of the reaction order of monoester formation to the 1st order reaction with respect to acid. The parameters of kinetic equations were detd.
