Sorption enhanced ethanol steam reforming on a bifunctional Ni/CaO catalyst for H2 production

Process improvement analysis of pyrolysis/gasification of biomass and waste plastics with carbon capture and utilisation through process simulation

“…This is because the water-gas-shift (WGS) reaction may be hindered. H 2 is the main product of pyrolysis/gasification process with high economic benefits, which can bring the majority of profits [11,24]. It is not practical and meaningful if the H 2 production is decreased a lot.…”

Insight into CO selective chemisorption from syngas mixtures through Li2MnO3; a new H2enrichment material

“…These multiple processes not only reduce the carbon oxides concentrations of the final effluent gas, but shifts the thermodynamic reaction equilibrium towards H 2 production. Within this context, calcium oxidecontaining ceramics seem to possess excellent properties as carbon oxides captors within the sorption-enhanced processes, [5][6][7][8] although other alkaline and earth-alkaline ceramics have also been analysed, such as MgO and Li 4 -SiO 4 . [9][10][11] All these works have evidenced that SER processes exhibit great potential in decarbonizing hydrogen production.…”

“…22 Thus, these lithium manganates selectively trap CO in moderate and high-temperature ranges in non-oxidative atmospheres (reactions 6 and 7). 2Li 2 MnO 3 + CO → Li 2 CO 3 + 2LiMnO 2 (6) 2LiMnO 2 + CO → Li 2 CO 3 + 2MnO (7) Based on the above, this work aims to analyse further the CO oxidation-capture of the Li 2 MnO 3 material, this time in the presence of hydrogen, employing a syngas flow mixture (CO + H 2 ). This goal was achieved by exploring the bulk and surface reactivity through TGA, GC, and DRIFTS techniques, which helped to establish the selectivity towards the CO oxidation-capture over the H 2 oxidation.…”

Effect of Sr Substitution on the Novel La1-xSrxCo0.5Ni0.5O3-δ Perovskite-Type Catalysts for Hydrogen Production in Ethanol Steam Reforming

“…They found that after the addition of Cu, due to the synergistic effect of Ni-Cu, the conversion of ethanol in different temperature ranges increased, and ethanol can be completely converted at 500 °C. Cortazar et al showed that 10 wt% NiO/CaO bifunctional catalyst performs well in adsorption enhanced ethanol steam reforming at 600-750 °C [14]. Martinelli et al discussed the effect of sodium loading on Pt/ZrO 2 during ethanol steam reforming [15].…”
