This study proposes a dual-purpose strategy that integrates turquoise H-2 production with the valorization of carbon nanostructures (CNSs) obtained from CH4 pyrolysis for use as asphalt modifiers. Ni-Cu-Al catalysts with different Ni/Cu ratios (0.5-4.0) were synthesized via combustion and evaluated for CH4 pyrolysis at 700 degrees C. The catalyst with Ni/Cu = 0.5 achieved 83…
The study explores the feasibility of producing ruthenium catalysts supported on char through a one-pot synthesis, an original approach for the preparation of noble metal-based catalysts in this field. This method combines hightemperature stages, such as catalytic support carburization and catalyst activation, in a single step. The innovation represents a significant advancement in utilizing cellulose…
The reverse water–gas shift (RWGS) reaction provides a sustainable route for CO2 valorization by producing CO, a key intermediate for various industrial applications. Its endothermic nature and the competition with Sabatier reaction impose a practical challenge on the design of low and medium temperature RWGS catalysts thus hampering its integration with downstream units. In this study,…
High purity carbon structured devices have been prepared by resorcinol-formaldehyde polycondensation in aqueous medium and alkaline conditions with starch as a binder and various external carbon sources. Polylactic acid (PLA) templates have been used to perform the structures which, after controlled and fixed pyrolysis conditions, generate 3D carbon devices with tuneable geometry and properties, as…
This research illustrates the efficacy of hydrothermal carbonization (HTC) as a pretreatment method to improve the pyrolytic performance of wood-derived lignin-rich lignocellulosic biomass (LB), supported by thorough characterization of its derived products such as syngas, tar, and biochar. A systematic comparison of non-HTC-treated LB and HTC-treated LB through their respective pyrolytic-derived biochar (NLB, HLB) obtained…
The pressing demand for sustainable alternatives to fossil fuels coupled with environmental risks associated with inappropriate sewage sludge (SS) disposal calls for innovative valorization strategies that transform waste into value-added products. This study introduces a novel approach by directly incorporating zeolite catalysts (HZSM-5 and USY) into the hydrothermal carbonization (HTC) of SS, followed by…
The conformation of a NiCo catalyst promoted by CePr on FeCrAlloy thermally pretreated micromonoliths was investigated via washcoating using a colloidal suspension of the catalytic precursor (hydrotalcite, HT) without the use of additives. A high affinity was established between the nature of the reconstructed HT and the layer of the formed alumina microstructures obtained after…
