Since the beginning of industrialisation, the energy consumption in the world increased tremendously. As a consequence of the use of fossils fuels as main source of energy, the release of CO2 and other greenhouse gases (GHG) increased as well. Therefore, the concentration of CO2 increased from 280 ppm in the beginning of industrialisation to 400 ppm nowadays. This increase in atmospheric CO2 concentration leads to an increase of the atmospheric temperature. Considering the energetic consumption in the world, it is not realistic to imagine a near future without the use of fossil energies to limit the Global Warming. So, it is important to develop some methods to limit CO2 release. CCS (Carbon Capture and Storage) and DAC (Direct Air Capture) are the main technologies that aim to reduce the CO2 emissions. This thesis studies the DAC in two ways. At first, a review about the state of art about DAC is made. Then, the degradation of a particular amine-based solid sorbent, Lewatit® VP OC 1065 (Lanxess), is studied in a quartz tubular reactor regarding some main parameters : temperature in the reactor, duration of the experiment and composition of the feed gas of the reactor. The influence of these parameters is studied in order characterise the degradation of the sorbent. The main results of the thesis are the impact of oxygen on the degradation, greater than the impact of temperature, the measurement of pure thermal degradation below 150 °C and the weak effect of water on the degradation. Depuis le début de l'industrialisation, la consommation énergétique mondiale augmente de manière exponentielle. Les sources principales d'énergie étant les énergies fossiles, une quantité grandissante de CO2 et autres gaz à effet de serre se retrouve dans l'atmosphère. En particulier, depuis le début de l'industrialisation et jusqu'à aujourd'hui, la concentration en CO2 est passée de 280 ppm à 400 ppm. Cette augmentation de la concentration en CO2 dans l'atmosphère mène à une augmentation de la température moyenne mondiale. Et, considérant les consommations énergétiques du monde moderne, il n'est pas imaginable de se passer de ressources fossiles pour atténuer ce phénomène de réchauffement climatique. Il est donc important de développer des méthodes capables de capturer le CO2 afin de limiter les émissions de celui-ci. Les principales méthodes pour limiter ces émissions reposent sur la capture du CO2 et sur son stockage. Dans cette thèse, les méthodes se focalisant sur la capture du CO2 dans l'air ambiant sont considérées de deux manières. Premièrement, l'état de l'art des méthodes de capture du CO2 dans l'air ambiant est décrit. Ensuite, la dégradation d'un sorbent solide aminé spécifique, Lewatit® VP OC 1065 (Lanxess), fut étudiée. Ce sorbent était dégradé dans un réacteur tubulaire en quartz et sa dégradation étudiée selon certains paramètres principaux : la température dans le réacteur, la durée de l'expérience et la composition du mélange gazeux entrant dans le réacteur. Le but de cette étude était de caractériser la dégradation de ce sorbent. Les résultats principaux de la thèse concernent l'influence de l'oxygène, démontrée comme plus importante que celle de la température, les mesures de dégradation thermique pure en dessous de 150 °C et le faible effet de l'eau sur la dégradation.

The G.B. Elyakov Pacific Institute of Bioorganic Chemistry of the Far-Eastern Branch of the Russian Academy of Sciences (PIBOC FEB RAS) was founded in 1964 in Vladivostok in the Far East of Russia. Over many years, we have been carrying out studies on the natural products of both marine and terrestrial origin. In collaboration with many Russian and foreign scientists, we have investigated many hundreds of diverse biomolecules, including steroids and terpenoids, quinoid compounds and alkaloids, polysaccharides and lipids, enzymes and lectins, proteins, and peptides. The Institute has a collection of marine microorganisms (KMM) PIBOC, which includes more than 4000 strains of marine bacteria and more than 1000 strains of marine fungi. The biological activity of natural compounds is also being studied. This book includes the 14 manuscripts which covered almost all aspects of PIBOC research activity in the fields of bioorganic chemistry, biochemistry, organic synthesis of natural compounds, marine microbiology, and genetic engineering, and we hope it will provide interesting new information for scientists working in these fields.
