DP-2061 & DP-2062 Refinery Off Gas Purification Catalyst

DP-2061 & DP-2062 catalysts are designed for the recovery of high purity ethylene, propylene and hydrogen from refinery off-gas (ROG) streams. It is taylor made for selective hydrogenation of methyl-acetylene(MA), propadiene (PD), acetylene and dienes in the purification of FCC off-gas streams. These catalysts can also remove other contaminants such as oxygen, NOx, phosphine and arsine effectively at the same time. 
While tolerance to H2S in the FCC dry gas, DP-2061 & DP-2062 catalysts can also resistant to deactivation caused by traces of heavy metals in the stream and is able to be operated in high CO concentration without formation of Nickel Carbonlys. DP-2061 & DP-2062 catalysts operates in a cyclical mode with regeneration and the catalyst life time can extend to several years of service.
