Abstract: | A kinds of three way catalyst, Pd/CeZrO 2/γ Al 2O 3, was prepared in the paper. Effects of Space Velocity on T 30% ,T 50% and T 90% of the catalyst were tested and analyzed in detail, respectively. It is concluded that Pd/CeZrO 4 /γ Al 2O 3 has a high light off ability and good space velocity properties. |
