ABSTRACT:

The aim of this research work was to prepare the efficient catalyst to purify pollutant output gases such as SO2, NO2 and CO. This catalyst ,lanthanum cobaltat (LaCoO3) was prepared by the proper method in the analysis laboratory of Tabriz Oil .The first materials were chosen through calcination operation and the temperatures of operation related to the Tamman temperature, therefore the basis for the first material of catalyst was nitrate and aqueous and since we had no availability to lanthanum nitrate, lanthanum oxide was used to prepare the nitrate one. Before all else, the first materials of catalyst were mixed together with the equal mole proportions and then, at the lower and upper temperatures of Tamman temperature, calcination operation was performed. To determine the molecular structure, the XRD analysis was utilized and specified that prepared lanthanum cobaltat was sixth aqueous and had the crystal structure type Triclinic.

KEYWORDS:
