2026-06-29 Dataset of Molten Metal-Catalyzed Methane Pyrolysis for Hydrogen Production under Different Operating Conditions doi:10.57760/sciencedb.39867 en The title of this dataset is "Dataset of Molten Metal Catalytic Methane Thermal Cracking for Hydrogen Production under Different Operating Conditions", mainly derived from experiments on molten metal catalyzed methane thermal cracking for hydrogen production. The experiment uses methane as the reactant gas and conducts non oxidative cracking reaction in a high-temperature molten metal system to generate hydrogen gas and solid carbon products. The dataset records key performance indicators such as methane conversion rate, hydrogen yield, and hydrogen selectivity under different reaction conditions, which can be used to analyze the effects of reaction temperature, inlet flow rate, inlet position, molten metal layer height, and gas distribution on the hydrogen production performance of methane thermal cracking. The experimental setup mainly includes a vertical tube furnace, quartz reaction tube, 316L stainless steel inlet tube, gas mass flow control system, molten metal reaction medium, and gas chromatography analysis system. During the experiment, the outlet gas composition under different operating conditions was obtained by controlling parameters such as reaction temperature, gas flow rate, and inlet position, and further results such as methane conversion rate, hydrogen selectivity, and hydrogen yield were calculated. After normalization, internal standard correction, and formula calculation, the raw gas composition data is organized into tabular data, which is then summarized, calculated, and graphically plotted using software such as Excel and Origin. The dataset does not involve large-scale geographic spatial distribution information, and its spatial information is mainly reflected in the structural parameters of the experimental reactor and reaction location parameters, such as the inner diameter of the quartz tube, the height of the molten metal layer, the height of the inlet from the molten metal liquid surface, and the aperture of the gas distributor. The main column labels include reaction temperature/℃, total inlet flow rate/mL · min ⁻¹, methane volume fraction/%, nitrogen volume fraction/%, molten metal composition, molten metal mass/g, molten metal layer height/mm, inlet height from liquid level/mm, gas distributor aperture/μ m, outlet gas composition/%, methane conversion rate/%, hydrogen selectivity/%, hydrogen yield/%, etc.  methane pyrolysis; molten metal catalysis; low-carbon hydrogen production Zhong Lei Wang Xiaobo PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
