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.},

abstract = {A new reactor for process intensification using sorption enhanced reaction is described. The novelty compared with most experimental work is that a continuous sorbent feeding (CSF) provides a steady state operation. The sorbent increases the reaction rate of a reversible reaction. The reactor is based on the phenomena of segregation of solids in fluidized bed reactors by using a catalyst and a sorbent. Under certain conditions of density and particle size, the two solids segregate and the sorbent may be removed from the bed with only a small content of catalyst. The system has been experimentally tested in the hydrogenation of CO2 to methanol, using a zeolite as sorbent. A significant increase in CO2 conversion was achieved compared with the same reactor without sorbent.},
