CATALYTIC REFORMING METHOD OF GASOLINE FRACTIONS Russian patent published in 2013 - IPC C10G59/02 C10G35/95 B01J29/50 B01J23/42 B01J27/10 B01J27/12 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to catalytic reforming method of gasoline fractions at increased temperature and pressure in presence of platinum erionite containing catalysts, which is implemented in block consisting of five in-series located reactors, in the first one of which (forcontactor) there performed is preliminary dehydration of cyclohexane hydrocarbons contained in raw material, in presence of halogen-containing platinum catalyst, and in the next reactors (from the second one to the fifth one) there performed is reforming process with subsequent increase in erionite content in modifications of catalysts in the direction of the supplied raw material. Reforming process is performed in presence of catalysts with the following content of erionite in them as to reactors: to the second (in the direction of raw material) and the third reactors there loaded are catalysts with erionite content in each of them, which is equal to 0.5-3.0 wt %, and the fourth and the fifth reactors - with erionite content of 2.5-3.7 wt %; at that, to forcontactor there loaded is platinum catalyst containing mixture of fluorine and chlorine as haloid.

EFFECT: improvement of reforming process properties - activity, selectivity and stability.
