Catalyst Systems

The catalysts based on V/K/Ca and V/Ks/Ce systems for diesel soot catalytic oxidation were synthesized onto the porous alumina substrates. Both catalyst systems showed a good catalytic oxidation activity. The V/K/Ca system exhibited the lowest oxidation onset temperature (OOT) of about 359oC with a composition of V/K/Ca =1:1:0.1 where the V and Ca and/or K elements could form a kind of amorphous phase that determined the catalytic activity. The V/Ks/Ce system displayed the lowest OOT of about 350oC with a composition of V/Ks/Ce = 1:2:0.1 where the K2SO4 and K5V2O3(SO4)4 phases could contribute most to the catalytic activity.
