The depletion of resources and the accumulation of pollutant gases in the atmosphere are nowadays of growing concern. The current energy transition requires that certain material and energy transformation processes be partially modified or profoundly reconsidered to fit more sustainable operating conditions. Low-carbon electricity and hydrogen can substitute fossil fuels, leading to an energy mix with a low greenhouse gas (GHG) footprint. In addition to hydrogen, the production of alternative fuels and high value-added products is another way to support the energy transition.Looking for optimal, sustainable and economical processes is therefore a major challenge that process engineers are facing. The present work has thus focused on the intensification of mass and energy transformation processes, through multifunctional units, which take advantage of the synergies between elementary functions of transformation (reaction, transfer, separation, etc.) within an intensive equipment. The concept of multifunctional reactors, coupling several elementary functions, has been a real success when historical demonstrators were created (Eastman-Kodak process, etc.), but their implementation has not been generalized, due to a lack of practical design methodology.This work focuses on the implementation of some intensification methodologies to understand and improve the performance of a process involving balanced exothermic reactions. The dimethyl ether (DME) direct synthesis from CO₂ and H₂ is considered as a case study. Different exploratory ways for the DME direct synthesis process development have been investigated based on modeling and simulation. Reactor- Heat exchanger, multifunctional reactor (reactor-heat exchanger-membrane separator), hybrid elementary block processes and a process involving the cooled reactor in a conventional process environment in the presence of additional unit operations and recycle loop are studied from different angles. Different optimization cases and strategies have been addressed which differ by the decision variables and the solving method. The different methodologies applied have demonstrated the relevance of the solutions obtained and the opening towards process innovation.At the equipment level, the profiles optimization represents the heart of the methodology. The results demonstrate the potential of multifunctional reactors: a CO₂ conversion per pass of 98%, a DME yield of 95% and the possibility to remove a distillation column are obtained. In order to assess the maximum achievable performance in a multifunctional reactor, a hybrid process of elementary blocks has been optimized. At the process scale, the reactor behavior has been studied to further understand the impact of the reactor integration in a recycle loop and to estimate the local and global effects on the multiple performance criteria. Based on various criteria (overall DME yield, overall CO₂ conversion, TRL, etc.), the comparison of the different designs revealed that a reduction of the equipment number by a factor of 11 is possible in the case of a multi-functional reactor choice

Steam Methane Reforming (SMR) of natural gas is characterized by generation of an excess of steam and their low thermal efficiency resulting in a very large device with important heat losses. One of the possible keys to make this process more profitable is to optimize heat transfer by changing the reactor design. A microstructured heat exchanger reactor has been retained. It enables to have fast heat and mass transfers and therefore allow increasing catalytic activity. However, this change in production technology must be accompanied by the development of highly active catalysts (MgAl2O4) that enable to reach high methane conversion (80%, 20 bar, 850°C) at low residence time (150 ms). The concept feasibility and catalysts performance have been validated on one channel in industrial process conditions. Then, a detailed model for acquisition of reaction kinetics has been developed and validated from experimental catalytic tests. For heat exchanger reactor design, two modeling approaches have been developed: by considering that the catalyst is highly active and enables to reach instantaneous equilibrium conversion on the coated catalytic walls of the reactor and by tacking the measured kinetics. Simulation of these models by considering technical constraints on the design enabled to find channel characteristic dimensions, heat power needed and the optimum number of channel which determine the heat exchanger reactor volume. Two fast methods for preliminary design of heat-exchanger reactors have been developed. By using heat exchanger reactor, it is possible to suppress steam excess generation and to reduce syngas production cost

Current silicon micro-machining techniques make now possible the manufacturing of micro-structured reactors with inner dimensions as low as a few micrometers. A major consequence of their high surface-to-volume ratio is a significant increase of heat and mass transfers which make them appropriate for the investigation of demanding reactions. In spite of the increasing amount of research in this field, very few devices can be used at both high pressure and temperature for the study of gas-liquid reactions. Therefore, several film and dispersed phase contactors have been designed and manufactured, notably with the help of Computational Fluid Dynamics. Taylor flow based contactors, considered as the more convenient in terms of hydrodynamics, were caracterized using an asymetric hydrogenation (30°C, 1-5bar) as well as a partial liquid phase oxidation (200°C, 25bar). Thanks to the intrinsic safety of micro-channels, the latter was also conducted with an enriched oxygen gas feed, thus leading to a significant improvement of the reactor’s productivity
