CATALYST OF HYDROGENATION OF ARENES AND THE METHOD OF ITS PREPARATION Russian patent published in 2007 - IPC B01J23/42 B01J21/04 B01J29/68 B01J32/00 B01J37/02 

FIELD: chemical industry; petrochemical industry; other industries; methods of production of the catalysts of hydrogenation of arenes.

SUBSTANCE: the invention is pertaining to the field of the catalytic chemistry, in particular, to production of the catalysts used for dearomatization of the diesel fractions. The invention presents the catalyst for hydrogenation of the arenas containing platinum the carrier, which aluminum oxide containing of no more than 500 ppm of impurities in the mixture with the crystalline mesosculiferous aluminosilicate with the molar ratio of Si/Al equal to 10-60 at the following contents of the ingredients (in mass %): platinum (Pt) - 0.15-0.60; aluminum oxide (AI₂O₃) - 59.85-94.4; crystalline mesoosculiferous aluminosilicate (Al_xSi_yO_z) - 5-40, where х = 0.017 - 0.1; y = 1; z = 2.026 - 2.15. The invention also presents the method of preparation of the catalyst of hydrogenation of the arenes providing for production of the carrier, deposition of platinum on the carrier by the method of the competitive impregnation from the combined solution of the carrier from the joint solution of the chloroplatinic acid, acetic acid and hydrochloric acid the subsequent drying, and burning, differing that the carrier is produced by mixing of the powdery aluminum oxide containing of no more than 500 ppm of the impurities, and the crystalline mesoosculiferous aluminosilicate Al_xSi_yO_z, (where х = 0.017 - 0.1; y = 1; z = 2.026 - 2.15), with the molar ratio molar ratio of Si/Al equal to 10-60, humidification of the produced mixture and the jellification by the 1.5 - 5 % solution of the nitric acid. The technical result of the invention is the increased hydrogenating activity of the catalyst.

EFFECT: the invention ensures the increased hydrogenating activity of the catalyst.
