Synthesis of Deodorant Catalyst using Noto-diatomaceous Earth

Abstract

Noto-diatomaceous earth is porous material that is composed of diatom shell and clay mineral. The pore of diatom shell is macro pore, and the pore of clay mineral is nano meter size pore. Pellet type catalyst carrier was prepared from Noto-diatomaceous earth. Deodorant catalyst was synthesized using this carrier. The catalyst performance was evaluated with fixed-bed continuous-flow reactor using 0.2%CO-2%O₂-N₂ mixed gas. The CO oxidation was occurred at room temperature by powder type Pd-catalyst. In case of pellet type Pd-catalyst, CO oxidation occurred at 170°C.
