• 中文摘要： 本文採用.gamma.-氧化鋁擔載的氧化銅、鉑-鈀、鉑-鈀-氧化銅觸媒進行二行程機車排放的粒狀物質之催化氧化反應研究。觸媒先裝於機車排氣管進行粒狀物質附著。經乾燥後,將附著有粒狀物質的觸媒置於流動式反應器中,然後將含有2%氧氣的氮氧混合氣體以每分鐘300毫升之流速流過。氧化速率在423與723K之間測定。結果顯示,鉑-鈀-氧化銅觸媒對機車粒狀物質的燃燒是有效的。本文亦顯示粒狀物質的氧化反應主要發生在觸媒的外表面上。由於鉑與鈀在觸媒外表面上與氧化銅密切的合作,所造成的協合效應大大地增進粒狀物質的轉化。
• 英文摘要： Catalytic oxidation of soot particulates from a 2- stroke motorcycle was studied. .gamma.-alumina supported CuO, Pt-Pd, and Pt-Pd-CuO catalysts were employed. The catalyst was coated with the motorcycle soot by being placed in an exhaust pipe. Following drying, the coated catalyst was placed in a flow reactor and a gas mixture containing 2% oxygen and balance nitrogen was led through it at a flow- rate of 300ml/min. The oxidation rate was determined at between 423 and 723K. The Pt-Pd-CuO catalyst was indicated by the result to possibly be effective for the combustion of motorcycle soot . Additionally, the soot oxidation was inferred from observations in this work to primarily occur on the external surface. A synergistic effect also occurred as a result of the Pt and Pd species being closely associated with the CuO species on the external surface and has consequently substantially increased the soot conversion.
