Study of low temperature combustion performance for composite metal catalysts prepared via rotating packed bed

Abstract

Abstract The study considered the preparation of a Mn/Cu catalyst using an RPB (rotating packed bed) and assessed the feasibility of the catalytic combustion of toluene gas. AC (activated carbon) was selected as the carrier material while copper and manganese were used as the catalytically active phases. The catalyst was characterised using BET, XRD, SEM, ICP-MS, XPS and TPG. The RPB-prepared catalyst exhibited a good dispersion for the metal particles and had a higher loading, which effectively increased the catalytic conversion of toluene. It was observed that the catalyst prepared under a high rotation speed and the same mass ratio of Mn and Cu had a superior catalytic activity. The results further show that RPB can successfully prepare metal catalysts for the catalytic combustion of VOCs (volatile organic compounds).
