METHOD TO ACTIVATE LIGHT GASOLINE FRACTION ISOMERISATION CATALYST Russian patent published in 2010 - IPC B01J38/02 C10G35/85 B01J23/44 B01J23/30 B01J38/06 B01J23/42 B01J21/04 B01J23/10

Abstract RU 2404857 C1

FIELD: chemistry.

SUBSTANCE: invention relates to activation of catalysts. Proposed invention covers activation of catalyst of isomerisation of light gasoline fractions that contains platinum and/or palladium on oxide carrier with elements of the 3^rd, 4^th and 6^th groups of periodic system by drying in dry airflow at increased temperatures, blowing by inert gas and reducing by hydrogen at increased temperature and pressure. Proposed method differs from known procedures in that hydrogen treatment is performed with water addition in amount of 5 -20 m/n^-1.

EFFECT: increase in specific activity of catalyst.
