In a previous study, Carberry et al. (1,2) have reported that strontium-doped solid oxide solutions of the formula La[sub 1[minus]x]Sr[sub x]CrO[sub 3[minus][delta]] exhibit similar catalytic activity to the Pt/Al[sub 2]O[sub 3] catalyst. The level of strontium doping at about 20 mole% in the perovskites resulted in the maximum catalytic activity for oxidation reactions. In continuation of earlier work, the authors decided to examine the catalytic activity of La[sub 0.8]Sr[sub 0.2]MO[sub 3[minus][delta]] oxides (M = Cr, Mn, Fe, Co, or Y) for hydrogenation reactions. Matthias et al. have shown the A site substituted manganese perovskite of the type La[sub 1[minus]x]A[sub x]MnO[sub 3] (A = Pb, Sr, Ca, or Ba) to exhibit promising catalytic activity for treating the internal combustion engine exhaust gases. They showed that the catalysts were efficient in both oxidation reaction of CO and reduction reaction of NO by H[sub 2]. Many published results on the hydrogenation and hydrogenolysis of hydrocarbons were centered around the ethylene hydrogenation over LaCoO[sub 3]. The propylene hydrogenation activity over La[sub 0.8]Sr[sub 0.2]MO[sub 3[minus][delta]] has not been reported, so far, in the literature. The objective of the present work is to monitor the catalytic efficiency of La[sub 0.8]Sr[sub 0.2]MO[sub 3[minus][delta]] in reducing atmosphere viz., propylene hydrogenation and the choice of propylene as reactant have no bearings on an practical applications. 15 refs., 1 fig., 1 tab.
