A study on utilization of stainless steel wire cloth as a catalyst support
E-mail:
In this work, stainless steel wire cloth (SSWC) for metallic support was thermally treated to increase the adhesive strength of Al2O3 by improving superficial roughness. After coating Al2O3 on SSWC, Pt particles as a catalytic component were deposited on the Al2O3/SSWC. These supports and catalysts were characterized by N2 gas adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM) in conjunction with energy dispersive spectroscopy (EDS), and scanning transmission electron microscopy (STEM). The catalytic performance was tested in the ethylene oxidation. The effect of space velocity (GHSV = 2000-8000 h^(-1)) at different temperatures (190 ℃ and 210 ℃) and reproducibility were investigated. The superficial roughness of SSWC was markedly increased by thermal oxidation at 800 ℃ for 12 h, and good adherence of Al2O3 to the SSWC was observed. The obtained Pt/Al2O3/SSWC800 catalyst showed excellent catalytic activity in the ethylene oxidation and showed a good reproducibility
and stability even after repeated use.
