“…Depending on the substrate, the reaction temperature is widely different, e.g. 180 °C for methanol, 400-600 °C for different alcohols or oxygenate substrates, 700-900 °C for hydrocarbons such as methane [15][16][17]. The catalysts are either based on noble metals (e.g.…”

Hydrogen production from renewable sources is gaining increasing importance for application as fuel, in particular with high efficiency and low impact devices such as fuel cells. In addition, the possibility to produce more sustainable hydrogen for industrial application is also of interest for fundamental industrial processes, such as ammonia and methanol synthesis. Catalytic processes are used in most options for the production of hydrogen from renewable sources. Catalysts are directly involved in the main transformation, as in the case of reforming and of electro-/photo-catalytic water splitting, or in the upgrade and refining of the main reaction products, as in the case of tar reforming. In every case, for the main processes that reached a sufficiently mature development stage, attempts of process design, economic and environmental impact assessment are presented, on one hand to finalise the demonstration of the technology, on the other hand to highlight the challenges and bottlenecks. Selected examples are described, highlighting whenever possible the role of catalysis and the open issues, e.g. for the H2 production from reforming, aqueous phase reforming, biomass pyrolysis and gasification, photo- and electro-catalytic processes, enzymatic catalysis. The case history of hydrogen production from bioethanol for use in fuel cells is detailed from the point of view of process design and techno-economic validation. Examples of steady state or dynamic simulation of a centralised or distributed H2 production unit are presented to demonstrate the feasibility of this technology, that appears as one of the nearest to market. The economic feasibility seems demonstrated when producing hydrogen starting from diluted bioethanol.

“…These include metals like Ni, Fe, and Co, and others. Various studies ( Khan et al, 2016 ; Abdullah et al, 2017 ; Chen et al, 2020b ; Baig et al, 2021 ) have shown the effects of different metal oxide supported catalysts like La 2 O 3 , ZiO 2 , Al 2 O 3 , SiO 2 , and TiO 2 involved in producing hydrogen ( Kim et al, 2011 ; El Hakim et al, 2021 ). In a study by Ibrahim et al , it was found that Fe over La 2 O 3 showed promising results for TMD at temperatures ranged between 500 and 700°C.…”

Consumption of fossil fuels, especially in transport and energy-dependent sectors, has led to large greenhouse gas production. Hydrogen is an exciting energy source that can serve our energy purposes and decrease toxic waste production. Decomposition of methane yields hydrogen devoid of COx components, thereby aiding as an eco-friendly approach towards large-scale hydrogen production. This review article is focused on hydrogen production through thermocatalytic methane decomposition (TMD) for hydrogen production. The thermodynamics of this approach has been highlighted. Various methods of hydrogen production from fossil fuels and renewable resources were discussed. Methods including steam methane reforming, partial oxidation of methane, auto thermal reforming, direct biomass gasification, thermal water splitting, methane pyrolysis, aqueous reforming, and coal gasification have been reported in this article. A detailed overview of the different types of catalysts available, the reasons behind their deactivation, and their possible regeneration methods were discussed. Finally, we presented the challenges and future perspectives for hydrogen production via TMD. This review concluded that among all catalysts, nickel, ruthenium and platinum-based catalysts show the highest activity and catalytic efficiency and gave carbon-free hydrogen products during the TMD process. However, their rapid deactivation at high temperatures still needs the attention of the scientific community.

“…Methane is highly abundant and the simplest alkane. The utilization of methane as a carbon source to produce chemical feedstocks has attracted much attention from the viewpoint of avoiding the depletion of petroleum resources. − However, the chemical conversion of methane is difficult due to its high stability. The catalytic conversion of methane is one of the effective approaches to solve this issue.…”

Rh ion-exchanged Y zeolite (Rh-Y) and amorphous silica−alumina (Rh-ASA) were prepared by the ion-exchange method. The Rh species were identified by UV−vis and IR spectroscopies, TEM, and H 2 -TPR measurements. Isolated Rh cations were preferentially formed on the Y zeolite, while Rh oxide mainly existed on ASA. The catalytic activities of the prepared samples for oxidative reforming of methane were evaluated. The Rh oxide on Rh-ASA exhibited slightly higher methane conversion and CO yield than those of the isolated Rh cation on Rh-Y. On the other hand, the catalytic lifetime over Rh-Y was longer than that over Rh-ASA because the isolated Rh cations were protected from aggregation by electrostatic interaction with the zeolite framework. In addition, Rh-Y exhibited a high catalytic activity even at low Rh contents owing to its high dispersibility. On the basis of the experimental facts, we have successfully clarified the active Rh species for this oxidative reforming of methane and demonstrated the effectiveness of the zeolite framework for the stabilization of the active species. This article provides the important concept for the design of highly active catalysts in this catalytic system.
