Optimization of the operating conditions for steam reforming of slow pyrolysis oil over an activated biochar-supported Ni–Co catalyst

Recent Solutions for Efficient Carbonyl Sulfide Hydrolysis: A Review

“…Carbon-Based Materials. The interest toward carbon-based materials has progressively increased in the past 10 years, 37,38 mostly because of the relatively low environmental impact resulting in their employment in a wide number of applications, for example, hydrocarbon conversion 39,40 and synthesis. 41,42 Also, in the scenario of environmental catalysis, activated carbons (AC) and biochar have been extensively studied and applied for removal treatments.…”

“…The interest toward carbon-based materials has progressively increased in the past 10 years, , mostly because of the relatively low environmental impact resulting in their employment in a wide number of applications, for example, hydrocarbon conversion , and synthesis. , Also, in the scenario of environmental catalysis, activated carbons (AC) and biochar have been extensively studied and applied for removal treatments. Activated carbons are well-known coal-derived materials, with a widespread application in wastewater treatment and H 2 S adsorption. − They are actually expensive materials, as they require high energy-intensive thermal activation in order to achieve the desirable adsorption properties. , On the other hand, biochar is less costly, and more important, it is a biomass-derived material, so even more environmentally friendly.…”

Addition of tungsten in Co/Al2O3 to catalyse the production of hydrogen through acetic acid steam reforming

“…Utilizations of noble metals, Pt, Pd and Rh, were limited because of their high cost [30] . Non‐nobel metal of Co was widely used because of its low cost and superior performance in C−C bond cleavage [31–33] . Ferreira et al.…”

“…[30] Non-nobel metal of Co was widely used because of its low cost and superior performance in CÀ C bond cleavage. [31][32][33] Ferreira et al prepared a Co/La 2 O 3 À SiO 2 binary catalyst for ethanol steam reforming, and found that the catalyst performed high activity. [34] Tang et al compared the performance of Co and Ni based catalysts (Co/OXAWSL and Ni/ OXAWSL) in toluene steam reforming for H 2 production, and found that the Co-based catalyst was more active and more stable than the Ni-based catalysts.…”

Tuning pyrolysis temperature to improve the in-line steam reforming catalyst activity and stability

“…With the aim of minimizing the deactivation of Ni reforming catalysts, numerous studies have focused on their optimization (Santamaria et al, 2021;Ashok and Kawi, 2021;Gao et al, 2021). On the one hand, alternative supports to the most used Al 2 O 3 have been studied (mainly ZrO 2 , TiO 2 , CeO 2 , MgO, SiO 2 (Huang et al, 2021;Santamaria et al, 2019;Men et al, 2007;Palma et al, 2018a) and diverse low-cost materials (Tang et al, 2021;Quan et al, 2020;Di Stasi et al, 2021) in order to provide the catalyst with high specific surface area, adequate pore distribution, mechanical strength, thermal stability and acidity or basicity. On the other hand, alkali metals (Li, Na, K), alkaline-earth metals (Mg, Ca, Ba), rare earth oxides (La 2 O 3 , CeO 2 ) or transition metal oxides (ZrO 2 , ZnO) have been incorporated into the catalyst as promoters (Alvarez et al, 2014;Lemonidou et al, 2013b;Santamaria et al, 2020a;Zhang et al, 2019) in order to improve its activity, selectivity and stability, as their incorporation enhances metal dispersion, reducibility, metal-support interaction and coke resistance.…”
