%X This paper aims at studying the catalytic activity of waste-derived chars for the reforming of a tar compound (ethylbenzene), and to identify the relationships between the modification process, the physicochemical properties and their resulting catalytic behaviour. Two chars were produced by pyrolysis: (1) used wood pallets (UWP), and (2) a mixture of food waste (FW) and coagulation-flocculation sludge (CFS) from wastewater treatment plant. Two chemical-free modification processes were separately applied to the pyrolysis chars: a gas phase oxygenation at 280 °C, or a steam activation at 850 °C. At 650 °C, the ethylbenzene conversion due to thermal cracking was significantly increased by the catalytic activity of the chars (from 37.2 up to 85.8%). Ethylbenzene was decomposed into six molecules: hydrogen, carbon dioxide, ethylene, benzene, styrene, and toluene. Cracking, oxidative dehydrogenation, and hydrogenolysis reactions were involved in the decomposition mechanism of ethylbenzene. The catalytic efficiency of the char was also discussed based on the energy transferred from tar to syngas during tar cracking reactions. The characterization, performed with SEM, XRD, Raman, XRF, BET and TPD-μGC, evidenced that the presence of mineral species in the metallic form strongly increased the syngas production and quality by catalysing aromatic-ring opening reactions and Boudouard reaction. The oxidation of mineral species, occurring during the oxygenation process, decreased the char efficiency, while rising SBET increased the syngas production for UWP-based chars. This study demonstrated that waste-based chars were efficient catalysts to convert the lost energy contained in tar into useful syngas, thus increasing simultaneously the syngas yield and quality.

%X District heating networks (DHN) arean efficient way of providing thermal energy to consumers. Current state of the art shows that DHNs are developing towards smart thermal networks in integrated energy systems while their design is based upon the principles of sustainability. Based on that, this thesis covers two main research areas: Operation and design of district heating systems. In part A of this thesis, advanced methods for DHN operation are developed with the help of exergetic and thermoeconomic analysis. This includes the formulation of exergetic cost balances for graph-based network models. Intrinsic part is the deployment of an algebraic matrix, which determines the exergetic costs for dynamic system modeling. A case study of areal-existing network provides evidence that the proposed methodology offers new insights into individual allocation of costs which helps to assess the feasibility of third-party integration and the integration of distributed energy sources. In part B of this thesis, a new indicator called “load deviation index (LDI)” is proposed to link demand side measures (DSM) with the sustainable design of DHN systems. For that, abusiness-focused design frameworks proposed which takes the critical influences of DHN into account while avoiding a too high detail. DSM behavior is analyzed from a system perspective and its impact on DHN design is studied in two case studies. While one focuses on benchmarks for different design options using a multi-criteria sustainability metric, another gives detailed insights into the usefulness of the proposed framework for design purposes through assessing the impact of DSM on possible design improvements using a multi-objective optimization approach.
%X Les réseaux de chauffage urbain (DHN) sont un moyen efficace de fournir de l'énergie thermique aux consommateurs. L'état actuel de la technique montre que les DHN évoluent vers des réseaux thermiques intelligents dans des systèmes énergétiques intégrés alors que leur conception est basée sur les principes de durabilité. Sur cette base, cette thèse couvre deux domaines de recherche principaux : Fonctionnement et conception des systèmes de chauffage urbain. Dans la partie A de cette thèse, des méthodes avancées pour le fonctionnement de la DHN sont développées à l'aide d'analyses exergétiques et thermoéconomiques. Cela inclut la formulation de bilans de coûts exergétiques pour les modèles de réseau basés sur des graphiques. La partie intrinsèque est le déploiement d'une matrice algébrique, qui détermine les coûts exergétiques pour la modélisation dynamique du système. Une étude de cas d'un réseau réel prouve que la méthodologie proposée offre de nouvelles perspectives sur l'allocation individuelle des coûts, ce qui aide à évaluer la faisabilité de l'intégration par des tiers et l'intégration des sources d'énergie distribuées. Dans la partie B de cette thèse, un nouvel indicateur appelé «load deviation index (LDI)» est proposé pour lier les mesures de la demande (DSM) à la conception durable des systèmes DHN. Pour cela, un cadre de conception axé sur les affaires est proposé, qui prend en compte les influences critiques dans le DHN tout en évitant un trop grand détail. Le comportement du DSM est analysé du point de vue du système et son impact sur la conception du DHN est étudié dans deux études de cas. Alors que l'un se concentre sur les benchmarks pour différentes options de conception en utilisant une métrique de durabilité multicritères, un autre donne des indications détaillées sur l'utilité du cadre proposé pour la conception en évaluant l'impact de DSM sur les améliorations de conception possibles.

%X District heating networks are commonly addressed in the literature as one of the most effective solutions for decreasing the greenhouse gas emissions from the building sector. These systems require high investments which are returned through the heat sales. Due to the changed climate conditions and building renovation policies, heat demand in the future could decrease, prolonging the investment return period. The main scope of this paper is to assess the feasibility of using the heat demand-outdoor temperature function for heat demand forecast. The district of Alvalade, located in Lisbon (Portugal), was used as a case study. The district is consisted of 665 buildings that vary in both construction period and typology. Three weather scenarios (low, medium, high) and three district renovation scenarios were developed (shallow, intermediate, deep). To estimate the error, obtained heat demand values were compared with results from a dynamic heat demand model, previously developed and validated by the authors. The results showed that when only weather change is considered, the margin of error could be acceptable for some applications (the error in annual demand was lower than 20% for all weather scenarios considered). However, after introducing renovation scenarios, the error value increased up to 59.5% (depending on the weather and renovation scenarios combination considered). The value of slope coefficient increased on average within the range of 3.8% up to 8% per decade, that corresponds to the decrease in the number of heating hours of 22-139h during the heating season (depending on the combination of weather and renovation scenarios considered). On the other hand, function intercept increased for 7.8-12.7% per decade (depending on the coupled scenarios). The values suggested could be used to modify the function parameters for the scenarios considered, and improve the accuracy of heat demand estimations. Abstract The work aims to evaluate the recovering potential of excess heat in the return pipe of a district heating (DH) for heating some substations. The proposed method combines a DH simulation tool and a multi-criteria decision aiding algorithm. It is based on the analysis of the measured return temperatures at each sub-station in order to identify those with high potential of efficiency gains by using the return flow (with support of the supply pipe when needed). Combinations of substations from this set of eligible ones define potential scenarios of connection to the return pipe. The impacts of each scenario on the DH operational performance and the energy savings are evaluated with a detailed hydro-thermal model. The technical parameters and the energy efficiency are not the only points of view in the selection process "of best compromise" scenarios for the improvement of the DH, so that we propose a complex decision aiding process, involving multiple criteria, dealing with different points of view (economic, energy, technical…) and different decision makers. The evaluations of the scenarios on the criteria are summed up in a so-called performance table and aggregated by an outranking model (MR-Sort) to identify relevant scenarios. This methodology is illustrated by the example of a part of the DH in Nantes (France). Interpretation of data from substations of a specific branch showed the potential of connecting some of them to the return pipe. Six scenarios were generated and evaluated with four criteria. Then, the Multi-criteria Decision Aiding method associated to two actors who have different priorities lead to not obvious results at a first glance.
