“…The characteristic peaks of two calcium aluminate phases (Ca 12 Al 14 O 33 and Ca 3 Al 2 (OH) 12 ) are detected in all of the catalysts. These calcium aluminate phases are usually observed in Al 2 O 3 -supported CaO-based materials. , The appearance of diffraction peaks of Ca(OH) 2 in all samples is due to the hydration reaction of CaO with humid air. , Meanwhile, the diffraction peaks of CaO are absent, supporting this hydration. The diffraction peaks (Figure a) at 37.2, 43.3, and 62.9° are attributed to NiO.…”

“…The used catalyst is denoted as n - R , and the regenerated catalyst as n - D , where n represents the number of cycles. Meanwhile, we have prepared the Ni–CaO catalyst as a reference catalyst by the incipient-wetness impregnation method . In brief, CaCO 3 powder was added into the aqueous solution containing desired Ni(NO 3 ) 2 ·6H 2 O with vigorous stirring.…”

Phenol is one of the major products of bio-oil derived from biomass pyrolysis. Sorption-enhanced steam reforming of phenol (SESRP) aiming to produce high-purity H2 has been carried out over Ni–Ca–Al–O bifunctional catalysts. The effect of bifunctional catalyst composition (Ni content, Ca/Al ratio) on H2 concentration, H2 yield, and phenol conversion was studied. The results indicated that 5Ni-CA2.8 was the optimized catalyst, over which 98.88% purity of H2 and ∼100% conversion of phenol were achieved under the optimum reaction conditions. The 5Ni-CA2.8 catalyst also provided excellent stability for 50 SESRP–desorption cycles (∼100 h), in which the H2 concentration and phenol conversion stabilized at 98 and 100%, respectively. Meanwhile, no coke was found during the long-term stability test.

In the present work, a reaction methodology was implemented using a batch reactor, which synthesized glycerol carbonate (GC) using glycerin and CaCO 3 . A crystallographic analysis of CaCO 3 was performed to determine its crystalline form. The obtained product was characterized by infrared spectroscopy, thermogravimetric analysis and nuclear magnetic resonance ( 1 H and 13 C). Our analysis demonstrated that the obtained product with the implemented reaction methodology has GC, FTIR showed the signals of the carbonyl groups, and the NMR spectrum confirmed the presence of cyclic carbonate structure in addition to linear carbonates. The thermogravimetric study showed that the thermal stability of the product is highly similar to that reported for GC. These results exhibit that the synthesis process produces linear and cyclic carbonates.

“…For dry reforming, different catalysts can be used, highlighting Ni, Rh, Ru, Ir, Pd, or Pt [20,[100][101][102][103][104], with coke accumulation and the sintering of catalyst particles (especially for Rh) as the main disadvantages, as in other cases [20]. In order to avoid coke accumulation, La was added to these catalysts to promote active sites, due to its redox property to remove carbon and its lower acidity compared to other popular catalysts such as Ni [100].…”

Recent Advances in Glycerol Catalytic Valorization: A Review

Once a biorefinery is ready to operate, the main processed materials need to be completely evaluated in terms of many different factors, including disposal regulations, technological limitations of installation, the market, and other societal considerations. In biorefinery, glycerol is the main by-product, representing around 10% of biodiesel production. In the last few decades, the large-scale production of biodiesel and glycerol has promoted research on a wide range of strategies in an attempt to valorize this by-product, with its transformation into added value chemicals being the strategy that exhibits the most promising route. Among them, C3 compounds obtained from routes such as hydrogenation, oxidation, esterification, etc. represent an alternative to petroleum-based routes for chemicals such as acrolein, propanediols, or carboxylic acids of interest for the polymer industry. Another widely studied and developed strategy includes processes such as reforming or pyrolysis for energy, clean fuels, and materials such as activated carbon. This review covers recent advances in catalysts used in the most promising strategies considering both chemicals and energy or fuel obtention. Due to the large variety in biorefinery industries, several potential emergent valorization routes are briefly summarized.
