Abstract

In this paper we work on prototype survey of using iron and manganese compounds in production of catalyst converter with nano particles for ROA dual fuel system instead of a lot of cerium in (La,Ce)(Pd,Co)O3-Perovskite catalysts and its comparison with imported catalyst of Iran Khodro with noble metals. (La,Ce)(Pd,Co)O3 Perovskite catalyst was prepared by the citrate route without use of Pt and Rh. We used just Pd (1.2 g) and it was deposited on ceramic monoliths according to a dip coating procedure. We used catalyst on RD car with XU7 motors model and measured the amount of emission with (AVL) test at Sapco Company and compared the catalyst with imported catalysts of Iran Khodro Company with noble metals such as Pd, Pt and Rh by Iran Khodro Company with Euro III standards. In conclusion Perovskite catalysts reduce emission better than imported catalysts, with lower emission and price. Monolite of catalysts were characterized by specific surface area measurements (BET) and X-ray diffraction (XRD) and X-ray fluorescence (XRF), and coat characterized by scanning electron microscopy (SEM). Finally the illustration shows Nano Particles size on coat.
