The present invention relates with the procedure for obtaining perovskite structure materials, for the emulsions reduction of sulphur oxides SOx in the catalytic disintegration units, FCC and/or fixed sources. These solids consist in Ti, Sr, Co, Mn Ce oxides with perovskite-type structure gathered in two series as follows: Ti0.6Sr0.4Co1-XMnX and Ce0.6Sr0.4Co1-XMnX, containing different concentrations of each one of these elements varying from X = 0 up to 1, which are obtained after mixing the aqueous solutions of metallic nitrates and ammonium hydroxides with a PH between 1-4, to obtain a suspension, giving it an average size particle of between 1 -50°.m. The obtained precipitates are homogenized by means of continuous agitation, between 5000-1 0000 r.p.m., during 0.5-10.0 hour. Finally, the materials are filtrated, dryed and calcinated between 600-1200°C in air flow between 2.0-8.0 lt/hour, during 2-20 hours, forming mesh particles of bewteen 80-300 °m, apropriated for the fluidized bed.
