CATALYST FOR REFORMING OF GASOLINE FRACTIONS, AND METHOD OF ITS PREPARATION Russian patent published in 2013 - IPC C10G35/85 C10G35/95 B01J23/42 B01J23/36 B01J21/04 B01J29/00 B01J27/47 B01J37/02 

FIELD: oil and gas industry.

SUBSTANCE: catalyst for reforming of gasoline factions is described; it contains platinum (possibly rhenium), chlorine, zeolite and gamma aluminium oxide, amorphous aluminium silicate at the following ratio of the above components, wt %: platinum - 0.1-1.0; (possibly) rhenium - 0.1-0.5; chlorine - 0.1-1.0; zeolite - 0.5-3.9; amorphous aluminium silicate - 1-2; gamma aluminium oxide - the rest. Reparation method of the above catalyst is implemented by mixing of powders of aluminium hydroxide with zeolite, peptisation of mixture with water solution of acid, granulation, heat treatment of obtained granules of carrier with further application to surface of active components - platinum in the form of water solution of platinum-chlorohydric acid and chlorine in the form of hydrochloric acid, drying and annealing of catalyst; at that, peptisation of mixture of powders of aluminium hydroxide with zeolite is performed with 0.5-20% water solution of organic acid, for example lemon, acetic and oxalic acids, and heat treatment of carrier is performed at temperature of 630-700°C.

EFFECT: increasing activity, stability and selectivity of catalyst.
