METHOD OF PREPARING SUPPORT FOR LIGHT GASOLINE CUT ISOMERISATION CATALYST AND SUPPORT FOR LIGHT GASOLINE CUT ISOMERISATION CATALYST Russian patent published in 2010 - IPC B01J32/00 B01J23/30 B01J21/06 B01J21/04 B01J23/34 C07C5/27 

FIELD: chemistry.

SUBSTANCE: invention describes a method of preparing a support for a catalyst for isomerisation of light gasoline cuts, involving mixing aluminium and zirconium hydroxides, extraction, drying and calcination, wherein a hydrate of ortho-tungstic acid is also used during mixture and hydroxides of titanium and/or manganese may or may not be added, and the mixture is stirred at 60-100°C for 2-4 hours. Described also is a support for a catalyst for isomerisation of light gasoline cuts made using the method described above, where the said support contains aluminium and zirconium oxides as well as tungsten oxide and optionally titanium oxide and/or manganese oxide and is a composition of oxides: aAl₂O₃·bZrO₂·cWO₃·dMO₂, where M - Ti, and/or Mn; a=0.05-0.3; b=0.6-0.9; c=0.005-0.15; d=0 or d=0.001-0.015; a+b+c+d=1.

EFFECT: support made using the method described above has high strength ratio for a catalyst for isomerisation of light gasoline cuts, low content of dust and crumbs resulting in low loss, as well as high activity of the catalyst for isomerisation of light gasoline cuts prepared using said support.
