Dataset of Molten Metal-Catalyzed Methane Pyrolysis for Hydrogen Production under Different Operating Conditions

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.
