Abstract :

In this project, the prototype production of catalyst converter for dual-fuel automobiles was studied. La (Pd, Co, Ce) O3 Perovskite catalyst was prepared by the citrate route without the use of Pt and Rh.   The present researchers just used Pd (1.2 g) and deposited on ceramic monoliths according to a dip- coating procedure, used the catalyst on Rd car with XU7 engines, measured the amount of emission with (AVL) test at SAPCO Company, and compared the catalyst with imported catalysts of Iran Khodro Company.  In the end, it was found out that Perovskite catalysts reduced emission better than the imported catalysts, and they do so at a lower price.   Monoliths of catalysts were characterized by specific surface area measurements (BET), X-ray diffraction (XRD), X-ray fluorescence (XRF), and coat characterized by scanning electron microscopy (SEM), LINE SCAN and MAP.
