RH catalyst
RH catalyst is a kind of low-cost combustion catalyst ,which is produced by rare earth and transition metal as the active component and cordierite honeycomb as the carrier and suitable for catalytic combustion of Oxo organic compounds (ester, ketone, aldehyde, ether).
Based on transition metal added, they are divided into RH-Co catalyst (Co added),RH-Mn catalyst ( Mn added) and RH-CM catalyst (Co and Mn added).
