Experimental investigation on the partial oxidation of methane with the effect of shrunk structure

Huaming Dai et al.

Summary: A double-layer porous media burner with shrunk structure was designed to explore the partial oxidation of methane for hydrogen production. The results showed that the shrunk structure significantly influenced the flame position and temperature distribution, with the flame moving downstream as the inner shrunk diameter decreased and the shrunk height increased. The highest hydrogen yield of 43.8% was achieved with 8 mm diameter Al2O3 pellets. The reforming efficiency increased initially with increasing equivalence ratio, reaching a maximum value of 53.0% at 4= 1.5, and continued to increase with increasing inlet velocity. These findings provide theoretical guidance for controlling flame position and species production through the design of shrunk structure in porous media burners.

Effects of K doping over ordered mesoporous nickel-alumina catalysts on toluene steam reforming

Yang Du et al.

Summary: It was found that introducing an appropriate amount of potassium (K) can enhance the activity and stability of nickel-alumina catalysts in the steam reforming of coal/biomass tar. K doping enhances the adsorption capability of the catalysts, reducing the amount and graphitization degree of carbon deposits. Moreover, K doping reduces the acidity of the catalyst support, inhibiting the formation of carbon deposits. This study is of great significance for improving the industrial application of nickel-based catalysts.

Recyclable NiMnOx/NaF catalysts: Hydrogen generation via steam reforming of formaldehyde

Yongji Hu et al.

Summary: In this paper, a low-cost and efficient NiMnOx/NaF catalyst was developed by sol-gel method for formaldehyde steam reforming to produce hydrogen. The catalyst exhibited high hydrogen production performance and stability, achieving 100% hydrogen yield, 100% formaldehyde conversion, and 100% carbon balance. The surface micro-structure of the NaF carrier was dense, and the specific surface area of the NiMnOx/NaF catalyst was small, but it could still obtain high-quality catalytic activity. The catalyst quickly adsorbed and activated formaldehyde and H2O molecules, promoting the formation of formate intermediates and rapidly producing H2 and CO2.

Hydrogen Production by Ethanol Reforming on Supported Ni-Cu Catalysts

Qihai Liu et al.

Summary: This study prepared and tested bimetallic Ni-Cu catalysts with different Ni-Cu loadings for hydrogen production from ethanol steam reforming. The results showed that 30Ni5Cu/Al2O3-MgO and 30Ni5Cu/Al2O3-ZnO catalysts exhibited higher H-2 selectivity and better coke resistance. The strong interaction between Ni-Cu and Al2O3-ZnO (or Al2O3-MgO) contributed to the improved catalytic performance.

An Overview of Hydrogen Production: Current Status, Potential, and Challenges

Muhammad Younas et al.

Summary: Hydrogen as an energy carrier can provide a long term solution to sustainable and environmentally friendly fuel supply, but it must come from renewable sources to be truly considered a clean fuel. Electrolysis, contributing 4% of the world's energy demand, still faces challenges due to its high energy consumption. Plasmolysis has been suggested as a competitive alternative with lower power consumption and cost.

Highly active and stable catalyst with exsolved PtRu alloy nanoparticles for hydrogen production via commercial diesel reforming

Jaemyung Lee et al.

Summary: Liquid fuel reforming is an efficient method for hydrogen production in mobile fuel cell systems. However, the catalyst used in this process is susceptible to damage from coke formation and thermal sintering. In this study, an exsolved PtRu alloy catalyst was investigated for diesel reforming. The properties of the catalyst, including its crystal structure, electronic state, and surface morphology, were analyzed using XRD, XPS, and TEM. DFT calculations were also used to predict the energetics of metal exsolution and alloy formation on the catalyst's surface. The PtRu alloy catalyst demonstrated improved activity and stability, with a high resistance to coke formation and thermal sintering, compared to monometallic Pt and Ru catalysts.
