Redox Treatment

The change in phase composition and catalytic properties of a copper-containing catalyst for methanol synthesis which was deactivated under industrial operation was studied at its redox treatment. The possibility of catalyst partial reactivation was shown. Conditions of reactivation were choosen at the increase in catalyst running time.

Positive Effect

The effect of the addition of La3+ cations on the structural properties of Pt/WOх/ZrO₂ catalysts and the characteristics of catalytic activity in the process of hydroisomerization of n-heptane and benzene mixture was studied. The phase composition of the catalysts is represented by a solid solution of lanthanum cations in nanocrystalline zirconia of tetragonal modification with localization of lanthanum in the surface layers predominantly. The positive effect of La3+ additives on the selectivity and yield of isomerized products was shown
