Elia, Nathalie. "Valorisation énergétique de CO₂ via la méthanation par voie catalytique." Thesis, Littoral, 2019. http://www.theses.fr/2019DUNK0505/document.
This study concerns the valorization of carbon dioxide by the methanation process. It aims to develop effectiv catalysts for this reaction. The active species is metallic nickel. Different supports have been studied such as SiO₂, Al₂O₃, MgO, Y₂O₃ and CeO₂. These catalysts were prepared by the dry impregnation method. Initially, the different catalysts were characterized by different physicochemical techniques including X-ray Diffraction (XRD), Temperature Programmed Reduction (TPR-H₂), Temperature Programmed Desorption (TPD-CO₂), nitrogen adsorption (BET method) and hydrogen chemisorption. In a second step, the various catalysts thus prepared were tested in the CO₂ methanation reaction. The Ni/CeO₂ catalysts has the best catalytic performance, among the systems studied. The addition of ruthenium improves the catalytic activity and the stability of the catalysts. The catalyst Ru(0.5%)-Ni(5%)/CeO₂ is the most efficient, it has good catalytic activity and good stability even as a pressure of 10 bar. This makes it advantageous for an industrial application

Carbon Dioxide is a greenhouse which can be valorised by means of electrochemical valorisation into carbon monoxide. The main goals of the thesis consist in the theoretical determination of the conductive conditions leading to this electrochemical valorisation in alkali molten carbonates along with the study of the feasability of this electrochemical reduction in binary and ternary eutectics under experimental condition. CO2 solubility has been determined by manometric measure and increase along with the temperature. CO2 electrochemical experimental feasibility into CO in eutectics on gold plate electrode and graphite carbon has been prooved by cyclic voltamperometry for temperatures exceeding 550°C , without gold plate electrode preatreatement and with gold plate preatreatement by an pre-electrolysis at potential sligthly negative as the CO2 reduction potential. A global approach of reactional mecanisms implied in CO2 reduction is proposed

The purpose of this project is to answer a double environmental problem, while allowing creating a new way of valorisation of fat sludge while reducing the important sawdust stock produces by forest industry in their bringing an added value. The study consists in dewatering greasy effluents on filter press with lignocellulosic residues like additive of filtration. Dewatering makes it possible to reduce sludge volume and to make solid of liquid fat sludge what facilitates their handling in particular during transport. The tests carried out on various types of greases underline the part played by the sawdust during filtration as well as the identification of the optimal characteristics of the lignocellulosic additive. The sludge dewatered were perforated mixes some with green waste. The mixture is facilitated by the solid structure of greases avoiding the phenomenon of percolation through the wind-row as well as the loss of grease in the leachate. The compost was analyzed in order to assess its qualities for an agricultural use. The purpose is to replace the current additives of filtration, expensive and less effective with fat sludge, by lignocellulosic residues thus allowing the launching of a natural additive of filtration facilitating agronomic valorisation
Flourat, Amandine. "Valorisation de co-produits de filières agroindustrielles, de la chimie verte aux applications." Thesis, Reims, 2020. http://www.theses.fr/2020REIMS020.
The need for a shift to a green economy is becoming increasingly urgent as confirmed by the recent IPCC report. In order to support the structuring of sustainable agro-industrial sectors for the production of energy or commodities, the parallel development of markets with smaller volumes but with a very high added value is necessary. Among these high-potential markets, the health and cosmetics sectors are particularly promising. Two developments related to plant chemistry will be addressed by the prism of co-products generated after a first transformation of renewable resource.In the first place, the paper industry, in crisis, generates large quantities of sawdust that can be converted by flash pyrolysis into levoglucosenone. This chiral, bi-cyclic (5 and 7-membered) molecule with numerous chemical functionalities (ketone, acetal, alkene) is a platform compound opening up a vast field of opportunities for biosourced chemistry. Obtaining chiral molecules from levoglucosenone opens up applications in the pharmaceutical field, in the bio-control sector and also in the food industry.On the other hand, para-hydroxycinnamic acids obtained from agricultural residues such as wheat bran, rapeseed or sunflower meal or mustard bran represent a source of phenolic compounds with high potential. These molecules are known to possess a certain number of physico-chemical (anti-radical, anti-UV) and biological (anticancer, anti-inflammatory) activities. Pathways of functionalization of these molecules by synthetic methods respecting the concepts of green chemistry will be explored in order to improve these properties, especially for the production of anti-UV
Tali, El'hadj. "Valorisation d'un co-produit issu de l'hydrolyse de l'amidon dans l'industrie du béton." Lyon, INSA, 1994. http://www.theses.fr/1994ISAL0083.
The aim of the present research was the valorization of a by-product coming from the hydrolysis of starch as an admixture for mortars and concretes. The use of this by-product allowed an extended time of workability, a limited bleeding, and reduced plastic shrinkage and permeability. The mechanical strenghts at 16 hours were improved and those at 28 days remained constant. Moreover, it was shown that the formulation of the standard mortar is not adapted to caracterize the effect of a plasticizer on the time of workability. The water/cernent ratio is a dominant factor to ensure this workability. As bleeding can be prevented, the performances hardened concrete does not decrease
Provost, Margot. "Valorisation de la fraction protéique des co-produits de saumon : étude et optimisation." Thesis, Brest, 2016. http://www.theses.fr/2016BRES0045.
By-products are the not used parts and recoverable in the fish processing operations, such as heads, skins, bones or pulp. The processing industry of farmed Atlantic salmon (Salmo salar) generates about 50% of co-products, which are a source of high quality protein. This work is part of Pesk&Co project, which gather four industrial partners (Meralliance-Thai Union Yslab, SPF-DIANA, AGH-SOCOFAG) and one academic partner (LEMAR UMR 6539, UBO) in order to extract and characterize high value ingredients from farmed Atlantic salmon by-products (Salmo salar). The first aim of the thesis was to develop a method for extracting collagen from salmon skins by the setting up of a non-conventional process at LEMAR and finally developed it at pilot and industrial scale. The collagen obtained was characterized by different analytical methods (FPLC-SEC, SDS-PAGE, FTIR, rheology, microscopy). Then, enzymatic cross-linking assays of collagen with a microbial transglutaminase led to obtain a collagen hydrogel. The second objective of this work was focused on the hydrolysis under controlled conditions of salmon heads to generate functional peptides for aquaculture. Two enzymatic hydrolysis protocols have been developed and transferred at pilot scale. The hydrolysates were incorporated into diets to be tested on bass larvae (Dicentrarchus labrax). Both ingredients developed during this work have for future use to be commercialized and different markets and applications are targeted
Lebbar, Salim. "Valorisation biologique de co-produits de l'extraction de l'agar issu du Gelidium sesquipedale." Thesis, Limoges, 2018. http://www.theses.fr/2018LIMO0082.
This work aims at promoting the bioactive molecules initially present in Gelidium sesquipedale. The rhodophycea agarophytes, including Gelidium sesquipedale, are used for industrial extraction of agar, a phycocolloid with gelling properties, which they contain in abundance. A multitude of co-products are generated during the extraction of the agar. These co-products have only been studied a little, hence not valued, while they constitute a significant source of molecules of interest. Firstly, the industrial agar extraction process was adapted on a laboratory scale, in order to recover these coproducts, which were subsequently subjected to an analysis, which revealed the presence of carbohydrates as major components. They were submitted to a fractionation process to obtain oligosaccharidic fractions, with a potential of elicitor activity, and a yield estimated at 15.7% of dry Gelidium sesquipedale. Also, a follow-up of co-products from batches of Gelidium sesquipedale harvested in different years from 2014 to 2016, enabled the comparison of the composition of the various co-products, depending on the year of the harvest, and thus to evaluate the variability of the initial resource. In addition, the impact of an extraction factor, being the sodium concentration, and the comparison with an industrial co-product produced by this process, were carried out. The retained fractions were characterized by GPC, ESI-MS, NMR and permethylation that allowed the elucidation of the structures of the oligosaccharides they contain, and revealed in particular the presence of floridoside derivatives including Gal2glycerol, Gal3glycerol and Gal4glycerol, which are original molecules in Gelidium sesquipedale, not described to date in red algae. A final part consisted in measuring the activity of these fractions as elicitor that could be estimated on tomato plants through measurements of biochemical markers relating to the expression of defense reactions in the plant. In conclusion, the co-products from agar extraction represent a source of pSDNs (phyto stimulator of natural defense in the plant) and give a new perspective to the agar industry
Burton, Tobias. "Synthèse de morpholine-2,5-diones et de (co)polydepsipeptides pour la valorisation d'acides aminés." Electronic Thesis or Diss., Montpellier, 2020. http://www.theses.fr/2020MONTS110.
Over the course of this work, the elaboration and the organocatalysed polymerisation and copolymerisation of morpholine-2,5-diones, monomers derived from α-amino acids, was studied. Firstly, an experimental protocol was developed, allowing for the synthesis of morpholine-2,5-diones from different amino-acids. The latter was then used for the production of a mix of morpholine-2,5-diones from a blend of amino-acids. This mixture of morpholine-2,5-diones was subsequently copolymerised using different catalysts. Next, the ring-opening polymerisation of 3S-(isobutyl)morpholine-2,5-dione as well as its copolymerisation with lactide was investigated via organocatalysis using 1,8-diazabicyclo[5.4.0]undec-7-ene and a thiourea co-catalyst. This catalytic system granted great control over the synthesis of polydepsipeptides and poly(depsipeptide-r-lactide) copolymers. Finally, with the aim of reducing the environmental impact of the different reactions developed herein, mechanochemical and microwave-based procedures were investigated. Using these techniques, a range of morpholine-2,5-diones were successfully produced in a much simpler and faster manner whilst using considerably less solvent and energy. Mechanochemistry also proved successful for the organocatalysed ring-opening polymerisation of 3S-(isobutyl)morpholine-2,5-dione and its copolymerisation with lactide. This study grants access to the direct comparison between solution and mechanochemical based ROPs which is, to date, a mostly unexplored field
Gotico, Philipp. "Stratégies bio-inspirées pour la réduction catalytique et la valorisation du dioxyde de carbone." Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLS283/document.
The criticality of global warming urges for the advancement of science to reduce carbon dioxide (CO₂) emissions in the atmosphere. At the heart of this challenge is the development of sustainable catalysts that can help capture, activate, reduce, and eventually valorize CO₂. This PhD work tried to respond to this call by developing molecular mimics inspired by natural systems in the larger scheme of artificial photosynthesis. Firstly, it involved tracking the journey of a photon of visible light and how it is transformed to a reducing power able to reduce CO₂. Secondly, in search for more efficient and stable catalysts, new mimics were synthesized inspired by the exceptional performance of CO dehydrogenase enzymes (CODH) in reducing CO₂. Lastly, further understanding of CODH also led to a proof-of-concept that directly valorizes the photo-produced CO for the synthesis of isotopically-labelled amide bonds, a common motif in pharmaceutically-relevant drugs
Fromanger, Romain. "Etude des possibilités de valorisation des pentoses par fermentation alcoolique d'hydrolysats de paille de blé." Thesis, Toulouse, INSA, 2010. http://www.theses.fr/2010ISAT0038/document.
The yeast Candida shehatae was the model microorganism of the study. This yeast canconvert xylose and glucose into ethanol, unlike Saccharomyces cerevisiae traditionally usedin industrial processes, which cannot convert xylose. Performance optimization of ethanolproduction from xylose is performed through maximization of the following three criteria:volumetric productivity, final ethanol titer and yield of ethanol over xylose. To direct thecarbon flux towards ethanol production, the major parameter which must be controlled is thelevel of oxygen limitation. Cultures are carried out in fed-batch in mineral medium andperformed in two phases: the first one is not limited in oxygen and the second one is oxygenrestricted. A mean value of qO2 equal to 1.19 mmolO2/gX/h maximizes the three criteria ofperformance on xylose: ethanol yield (0.327 gETOH/g-xylose), the maximum specificproductivity (0.22 gETOH/gX/h) and the final ethanol titer (48.81 g/L). For glucosefermentation, ethanol yield is the highest (0.411 gETOH/g-glucose) when qO2 is low as anaverage value of 0.30 mmolO2/gX/h, while the specific productivity and the ethanol final titerreach maximum values of 0.35 gETOH/gX/h and 54.19 g/L for respectively qO2 of 1.7 and2.5 mmolO2/gX/h.For the simultaneous consumption of the two substrates, a phenomenon of glucose repressionover xylose is observed in chemostat experiment with glucose pulse on xylose steady state.The presence of intracellular enzymes of the xylose pathway (XR and XDH) is not sufficientfor efficient co-consumption of both sugars and glucose is preferentially consumed.In order to structure the knowledge obtained on the metabolism of C. shehatae and tooptimize by simulation the co-culture C. shehatae / S. cerevisiae to produce ethanol fromxylose/ glucose mixtures, a kinetic model of C. shehatae is built. This model is validated withpure substrate cultures (xylose and glucose separated). A kinetic model of co-culture is thenbuilt in order to simulate several fermentation strategies to optimize the ethanol productionfrom xylose/glucose mixture similar to wheat straw hydrolysates
