Abstract
En 中文
The synergistic application of nonthermal plasma (NTP) with catalysts has shown advantages in improving tar removal efficiency and target product selectivity. Kinetic studies of plasma participation in catalytic reactions are important for improving catalyst performance and designing efficient reactors. In this study, NixFey-HAP (Hydroxyapatite, HAP) catalysts were prepared by coprecipitation method. The kinetics of the benzene steam reforming reaction has been studied in depth by investigating the reaction properties of the catalysts at 550°C–650°C in a thermal catalytic (TC) system and graded postplasma catalysis (GPPC) system, respectively. The results show that Ni5Fe2–HAP–T exhibits the smallest activation energy of 88.1 kJ/mol in TC, thanks to the high dispersion of active site Ni due to the intervening order of Fe followed by Ni. In GPPC, the activation energies of Ni5–HAP–O, Ni5Fe2–HAP–O, and Ni5Fe2–HAP–T were 51.7, 99.7, and 70.6 kJ/mol, respectively, which were reduced by 48.0%, 10.4%, and 20.0%, respectively, compared with TC. The kinetic model of plasma-assisted benzene catalytic reforming changed significantly, tending to follow a more complex power law model attributed to the higher electrons and reactive radicals generated by NTP. The results may provide theoretical suggestions for reactor design and catalyst preparation for NTP-coupled catalytic process.
