- W2247129971 abstract "Influence of the nature and content of the promoter and catalyst activity and stability of Pd-Со/δ-Al2O3 и Pd-Zn/δ-Al2O3 bimetallic catalysts in the hydrogenation of diene and vinylaromatic hydrocarbon to BTX fractions was studied by IR spectroscopy and thermoprogrammed recovery. The molar ratio of Pd : Co (Zn) in the prepared samples – 1,0 : 0,5; 1,0 : 1,0; 1,0 : 1,5 the content of Pd – 0,5 wt.%. The support is δ-Al2O3 modified by sodium (0,5 wt.%). It is shown that promotion of cobalt and zinc leads to the disappearance of palladium cation forms, which reduces oligomerization capacity of the active component, and as it was confirmed by the 100-hour catalyst test the stability of the catalyst increases. The results showed that for the hydrogenation process of BTX fraction in industrial conditions it is Pd-Cо/δ-Al2O3(Na) catalyst with a molar ratio of Pd : Co = 1,0: 1,0, for which the expected service cycle operation is 16 months." @default.
