Effect of catalyst activity in SMR-SERP for hydrogen production: Commercial vs. large-pore catalyst

Lithium orthosilicate for CO2 capture with high regeneration capacity: Kinetic study and modeling of carbonation and decarbonation reactions

“…The removal of CO 2 from the reaction stream can both increase the concentration of the desired products and improve the overall efficiency [1][2][3][4].…”

“…One of the most promising techniques for CO 2 suitable materials are known to have good capacities for the sorption of CO 2 at high temperatures: CaO-based materials [5][6][7], hydrotalcites (HT) [2,4,8,9] and lithium based materials [10,11]. Activated carbons and zeolites have been widely used, though the low equilibrium temperature for adsorption (25-150°C) limits their application.…”

CO2 capture with calcined dolomite: the effect of sorbent particle size

“…A wide range of technologies for carbon-emission-free energy production are currently under development. A promising option involves in situ CO 2 capture in biomass/coal gasifiers [1][2][3][4] and in advanced configurations of the methane steam reforming process [5,6] as well. The "in situ" CO 2 capture is usually performed by means of a calcium-based solid sorbent and results in the formation of calcium carbonate, which can then be re-calcined for a further CO 2 capture cycle, while a carbon dioxide rich stream is generated amenable to sequestration or utilization.…”

Conclusions and Perspectives

“…This concept is also known in gas-phase processes as sorption-enhanced reaction processes, for hydrogen production by steam reforming of methane (Hufton et al, 1999;Oliveira et al, 2011) or ethanol (Wu et al, 2013), and sorption-enhanced water gas shift, demonstrated in the European project CAESAR (Jansen et al, 2013). In fact, systems with separate units for reaction and adsorption (separation) are more robust than integrated systems.…”
