TITANIUM DIOXIDE AND ALUMINIUM OXIDE-BASED COMPOSITION, METHOD OF THEREOF OBTAINING AND APPLICATION THEREOF Russian patent published in 2016 - IPC B01J27/53 B01J27/55 B01J21/06 B01J21/04 B01J23/04 B01D53/48 B01D53/52 B01D53/86 

FIELD: chemistry.

SUBSTANCE: catalytic composition includes the following components, wt %: aluminium oxide - 2.0-77.0; oxide and/or sulphate of alkali-earth metal - 1.0-6.0; sulphate ion - 2.0-9.0; titanium dioxide - the remaining part. As oxide component, titanium catalytic composition includes modified sulphated titanium dioxide, which is obtained by mixing, at least, one oxide and/or sulphate of alkali-earth metal with hydrated sulphated titanium dioxide with the following hydrothermal processing at temperature 50-120°C and drying. Method for obtaining catalytic composition includes said modified titanium compound, where further obtained modified sulphated titanium dioxide is dried, subjected to mechanical-chemical activation and mixed with hydroxide compounds of aluminium or modified sulphated titanium dioxide is mixed with aluminium hydroxide compounds with carrying out combined mechanical-chemical activation. Pore-forming additives and binding agent are added to obtained product, moulding, drying and thermal processing at temperature 300-700°C are carried out. Claimed composition makes it possible to obtain catalysts for heterogenic reactions, which have different composition, which can be formed depending on application and exploitation conditions.

EFFECT: development of catalytic composition based on aluminium oxides and titanium dioxide with different ratio of aluminium oxide and titanium dioxide with increased mechanical strength, thermal and hydrothermal stability and environmentally friendly method for its obtaining.
