METHOD OF PROCESSING LONG GASOLINE FRACTION Russian patent published in 2006 - IPC C10G59/06 C10G35/85 B01J23/42 B01J23/656 

FIELD: petroleum processing and petrochemistry.

SUBSTANCE: long gasoline fraction is divided into two streams, one of them being subjected to reforming process on industrial Pt-eryonite-containing catalyst SG-3P at 475-480°C, pressure 1.5-2.0 MPa, and volumetric feedstock flow rate 2.8-4.2 h-1, and the other being processed on platinum-rhenium catalyst KP-108 at 500-520°C, pressure 1.5-2.0 MPa, and volumetric feedstock flow rate 1.2-1.7 h-1. Before processing of the second stream, it is supplemented with 5-25% of the first-stream reforming product containing at least 8% of methylcyclopentane hydrocarbons.

EFFECT: simplified technology and increased octane number of reforming process.
