    Study on catalytic oxidation of low concentration 14CH4 by non-thermal plasma by PEI Jianlu, LIANG Shuwei, LIN Zhongxin, LI Jiayu, CHEN Jianli, HAN Ming, HOU Jianrong, LI Yongguo

    Published 2025-02-01
    “…The CH4 treatment performance of the non-thermal plasma before and after the introduction of the catalyst under different discharge voltages, gas flow rates and temperatures were analyzed by the constructed experimental system. The microstructural changes of the catalyst were analyzed by N2 adsorption-desorption isotherm, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS).ResultsThe introduction of Pd/Al2O3 catalyst can significantly improve CH4 treatment performance in non-thermal plasma, and the CH4 treatment efficiency and CO2 selectivity can reach 100% and 83.7% by increasing the discharge voltage, lowering the reaction temperature and reasonably adjusting the gas flow.ConclusionThe non-thermal plasma and the Pd/Al₂O₃ catalyst exhibit a synergistic effect. …”

    Published 2024-12-01
    “…Predictions using the neural network method were more accurate, with a relative error of less than 10% compared to measured values. 2) Using Kendall's tau-b correlation analysis, the discrete dominant factor was identified as the microstructural position, primarily located in uplifted positive structural zones, with the secondary factor being fracture development, categorized mainly as “well-developed” or “developed.” 3) By combining lasso regression-random forest- decision tree algorithm to iteratively eliminate irrelevant factors, the continuous dominant factors influencing productivity were ranked in descending order as: ash content, average construction discharge rate, total sand volume pumped, flowback rate at gas breakthrough, net pay thickness, acoustic travel time, gamma ray log value, average construction pressure, percentage of 100-mesh sand, and average gas measurement value. …”
