abstract = {This study demonstrates the influence of the functionalization method (Mechanical Mixture -MM- and Dual Function Materials -DFM-) of two CO2 adsorbent species (Na and Ca) in a catalytic fixed-bed reactor for CO2 methanation. The experiments consisted of cycles beginning with a CO2 adsorption stage followed by a methanation stage (with H2), interspersed with or without inert purge periods. The greatest enhancement in methane generation was observed in experiments with a mechanical mixture (MM) of NiFe/γ-Al2O3 catalyst and Na2O/γ-Al2O3. The methane production capacity was tested over a temperature range comprised between 200 and 400 °C, with values over 380 μmol/g obtained under moderate conditions (350 °C and pCO2 = 0.12 bar) and selectivity to methane close to 100 %. Since the ultimate goal is the methanation of the CO2 present in a biogas (without removing CH4), the potential effect of the presence of methane during the CO2 adsorption stages was also investigated. To achieve this task, a feed stream representative of a sweetened biogas coming from the anaerobic decomposition of municipal solid waste (MSW) (70 %v CH4 and 30 %v CO2) was used. The results showed no adverse effects along the successive cycles, paving the way to the use of these solids for biogas upgrading. On the other hand, the catalyst did not show a significant loss of activity after several hours of repetitive adsorption-methanation cycles.},

abstract = {The e-fuels synthesis via CO2 hydrogenation and the Sorption Enhanced Reaction technology are captivating strategies for CO2 utilization and the integration of renewable energy sources. This study focuses on enhancing the conversion of CO2 over an In2O3/ZrO2 catalyst by incorporating LTA zeolites (3A and 4A) and a FAU zeolite (13X). Key operational parameters, such as temperature (T), Gas Hour Space Velocity (GHSV), type of zeolite, and Zeolite: Catalyst mass ratio (Z/C), were systematically varied. LTA zeolites (3A and 4A) provided the highest CO2 conversions. The introduction of a water-adsorbing solid into the reactor significantly altered the products yield and selectivity. While the selectivity towards CH4, CH3OH, and C2H6O appeared to lay on the type of zeolite, the selectivity towards CO remained unaffected. Zeolite 3A demonstrated the greatest enhancement in selectivity towards CH4 and CH3OH, whereas the synthesis of C2H6O was favored by zeolites 4A and 13X. The Zeolite:Catalyst mass ratio also played a crucial role in process performance, influencing both CO2 conversion and product selectivity. Increasing this ratio improved CO2 conversion and reduced CO selectivity under all operating conditions, while CH4 selectivity increased. However, the selectivity toward CH3OH and C2H6O exhibited an anomalous and complementary behavior. While a maximum was observed for DME, a minimum was registered in methanol production, suggesting a dependency of the dehydration reaction kinetics on the amount of water produced during the reaction.},
