Abstract
A series of 2% Pd-Cu/ACC catalysts were prepared by selective deposition of Cu on Pd/ACC and examined at steady state in a continuous three-phase radial flow reactor. The activity and selectivity of the bimetallic catalysts depend on the Cu:Pd ratio and the metal loading. The beneficial effect of copper on nitrate hydrogenation activity with a Pd-Cu/ACC catalyst is probably related to the formation of an active Pd-Cu ensembles working as active sites for nitrate-to-nitrite reduction. The maximal nitrate conversion was achieved with 0.6Â wt.% Cu-2Â wt.% Pd/ACC catalyst showing a 92% selectivity towards gaseous products.
