The ever-growing carbon-based economy has led to alarming increases in greenhouse gas (GHG) emissions, particularly methane (CH4) and carbon dioxide (CO2). These emissions accelerate global warming environmental challenges. Methane Dry Reforming (DRM) offers a promising technology address this issue by converting CH4 CO2 into valuable syngas (CO + H2) mixture, which is fuel building block for the many important chemical reactions i.e. Fischer-Tropsch process. However, finding affordable environmentally friendly catalysts large-scale applications remains critical hurdle. This study delves development of stable nickel-zirconia prepared via impregnation method. weight percentage nickel zirconia was varied optimize catalyst's activity controlling deactivation phenomenon that major challenge at higher temperatures during DRM. Various characterization techniques (XRD, FT-IR, SEM-EDX, TGA, TEM, BET) were employed evaluate synthesized physio-chemical properties. Additionally, catalytic performance assessed ranging from 550 750 °C hourly space velocity (GHSV) 72,000 mL/h/gcat. Among tested catalysts, 15% Ni/ZrO2 displayed remarkable conversion values both (62.9%) (64.9%). Importantly, it exhibited significantly lower loss (ca. 15.42%) compared other variants, indicating better resilience against coke deposition. enhanced stability can be attributed synergistic interplay between support, effectively suppressing formation. findings demonstrate potential as catalyst experimental DRM application. With obvious high activity, stability, candidate serves an eco-friendly green energy, contributing sustainable economy.

A promising method for converting greenhouse gases such as CO2 and CH4 into useful syngas is the dry reformation of methane (DRM). 5Ni-ZSM-5 2 wt.% Ce, Cs, Sr, Fe, Cu-promoted catalysts are investigated DRM at 700 °C under atmospheric pressure. The characterization, including XRD, TPR, TPD, TPO, N2 adsorption–desorption, TGA, TEM, Raman spectroscopy, revealed that catalyst’s active sites distributed throughout pore channels on surface, contributing to stability catalyst. Specifically, CO2-TPO followed by O2-TPO experiment using spent confirmed oxidizing capacity during reaction. Ce-promoted catalyst showed greatest increase in catalytic activity among other catalysts. 5Ni+2Ce-ZSM-5 exhibited twice concentration acid compared Cs-promoted counterpart, even though both achieved similar quantities basic sites. Without compromising H2 CO selectivity, this finding underscores crucial role enhancing conversion. With a GHSV 42,000 mL/(h.gcat), demonstrated impressive conversion rates 42% 70% 800 °C. reactants spend more time over subsequent reduction 21,000 resulting best performance with 80% 83% conversions.
