|Biomimetic fixation of CO2 as source of salts and glucose|
Mar Garcia Alvarez
Global warming and climate change are issues of great concern today. The increasing of greenhouse gases emissions to the atmosphere is responsible for various environmental problems. Carbon dioxide (CO2) capture and storage can greatly reduce CO2 emissions from new and existing power plants. Membrane technology is highly considered as one of promising post-combustion technologies for reducing CO2 emissions due to its simple operability and energy efficiency.
The overall objective of this project is CO2 capture using membrane technology from flue gases by using bio-enzymes as catalysts by mimicking nature for converting into valuable chemicals.
Two enzymatic conversions will be studied in this project. The first one is based on the action of the enzyme carbonic anhydrase, which facilitates the reversible hydration of CO2 to bicarbonate. The second enzyme is RuBisCO (Ribulose-1,5-bisphosphate (RuBP) carboxylase/oxygenase). The great advantage of using RuBisCO is that this enzyme converts inorganic carbon to its organic form through the formation of a relatively high-molecular weight ligand in the form of phosphoglyceric acid, which may subsequently form glucose.
|Removal of azo dyes in textile wastewater using MFC and membrane technology|
Raul Alfonso Bahamonde Soria
The growing world population has increased the problem in the field of environmental pollution, one of the most alarming problems is the pollution of water due to industries, among which one of the largest is the textile industry. This wastewater contains azo dyes which are classified as one of the most difficult compounds to degrade. These dyes can cause very serious environmental problems due to their great stability in environmental conditions (long time it takes to degrade) and its high toxicity for certain aquatic microorganisms. There are several methods of degradation of azo dyes, some very innovative among which are microbial fuel cells, advanced oxidation processes and filtration membranes, as can be seen in the literature, most of the research is focused in attacking the particular problem, but not many efforts have been made together.
The main objective of this project is to increase the potential of these technologies, microbial fuel cells and photocatalytic membrane reactors for an efficient treatment of textile wastewater, on the other hand the modification of osmotic membranes will improve the anti-fouling characteristics as well as a greater durability of membrane filtration systems and photocatalytic membrane reactors to obtain a fast and efficient system when degrading these toxic compounds.
|CO2 post-combustion capture by means of membrane absorption-crystallization using amino-acid salts|
Climate change remains a huge challenge today. The most mature and popular CO2 capture method in post-combustion processes is the absorption of CO2 into a solvent, often MEA. Nevertheless it has been shown that this method could be improved both in terms of solvent and in terms of device. The project aims at studying the CO2 post-combustion capture by means of membrane absorption with amino-acid salts and convert the absorbed species into valuable carbonate crystals after a concentration step by means of a reverse osmosis (RO) membrane. The crystallization will be performed thanks to a membrane distillation-crystallization step. A comparison between the osmotic membrane distillation system and the vacuum membrane distillation system will be performed. This whole process should minimize the energy consumption thanks to the use of membrane technologies instead of absorbtion columns while producing pure crystals that could be sold in the industry.
|High performance membranes for CO2 capture involving advance materials and biomimicking Nature|
Cristhian Molina Fernandez
Global warming is a major problem of our current society. Since our energy demand is continuously increasing it is still expected to rely on fossil fuel supply in the following years. That is why much effort has been dedicated to find industrially feasible solutions to recover the CO2 present in flue gases. This research project aims to provide more and better solutions for CO2 capture and reutilization using membrane technology involving advance materials and biomimicking Nature.
|Rational Design of Metal-Organic Frameworks/Covalent Organic Frameworks Hybrid Membranes for Pervaporation |
MMMs have become one of the research hotspots in the field of separation membranes in recent years.In MMMs, the poor compatibility between fillers and organic polymers makes the membrane surface prone to defects, which leads to the decline of separation and stability of the membrane. Therefore, improving the compatibility between hybrid particles and polymers becomes an urgent problem to be solved.MOFs and COFs have the advantages of adjustable pore size, high specific
surface area, and organic components in the framework structure, which enhances compatibility with polymers and reduces defects.The super high specific surface area and selective adsorption characteristics of MOFs and COFs materials enable MOFs hybrid membranes and COFs hybrid membranes to simultaneously increase separation factor and permeation flux, breaking the "trade-off" phenomenon.
In this study, metal-organic framework complexes (MOFs) and covalent organic framework materials (COFs) will be used as hybrid particles.Hybrid membranes will be prepared by impregnation method and applied to the separation of organics/water.The separation performance of the pervaporation membrane will be improved by utilizing the characteristics of high specific surface area and selective adsorption of MOFs and COFs particles.The morphology and surface characteristics of the hybrid membranes under different membrane formation conditions will be studied by means of XRD, SEM, EDX, FTIR, CA, AFM, etc. And the effects of membrane formation factors and operating conditions on the properties of the separation
membranes will be investigated
|Efficient membrane-based affinity separations for chemical applications|
Tim Van Geel
Many chemical companies are nowadays confronted with very challenging liquid separations, aiming at separating molecules with very similar physical properties. The current trend towards more bio-based and/or highly-tailored chemicals, will only increase the number of these demanding separations. These challenges would benefit from efficient Affinity Separations (AS).
The most traditional AS technology is liquid-liquid extraction, where the extracting solvent acts as the separation agent (ASA). The most selective AS is liquid chromatography, driven by the affinity between molecules and a functionalised stationary phase, the separation material (ASM). Although successful in different situations, both AS processes have important drawbacks. The EasiChem project aims at tackling these limitations, by developing more efficient, and/or more sustainable AS processes, focusing on promising, energy-poor liquid separation technologies like membrane-based AS processes.
The goal of developing these membrane-based AS processes is to bring the selectivity of chromatography to membrane separations, using functionalised ceramic membranes tailored to match the separation problem. The work programme is intended to extensively explore, understand and benchmark the capabilities and limitations of this new AS process, using a myriad of functionalized ceramic materials.
A division is made between processes driven by an Affinity Separation Agent (ASA), and processes driven by an Affinity Separation Material (ASM). In addition to continuous chromatography, three promising membrane-based AS processes will be developed within the EasiChem project: open membrane extraction using hydrophobized ceramic microfiltration membranes (ASA process), innovative tight membrane extraction and affinity nanofiltration, both with functionalised ceramic membranes (ASM processes). Polymeric membranes will be used for comparison.
Within the framework of the EasiChem project, several work packages were defined, of which this research project represents work package 5. This work package deals with open membrane extraction using hydrophobized ceramic microfiltration membranes.
