GASOLINE AND DIESEL FUEL PRODUCTION PROCESS Russian patent published in 2005 - IPC

Abstract RU 2265042 C1

FIELD: petroleum processing and petrochemistry.

SUBSTANCE: hydrocarbon feed is converted in presence of porous catalyst at 250-500°C and pressure not higher than 2.5 MPa, feed uptake being not higher than 10 h-1. Hydrocarbon feed utilized are various-origin hydrocarbon distillates with dry point not higher than 400°C. Catalyst is selected from various aluminosilicate-type zeolites, gallosilicates, galloaluminosilicate, ferrosilicates, ferroaluminosilicates, chromosilicates, and chromoaluminosilicates with different elements incorporated into structure in synthesis stage. Resulting C₁-C₅-hydrocarbons are separated from gasoline and diesel fuel in separator and passed to second reactor filled with porous catalyst, wherein C₁-C₅-hydrocarbons are converted into concentrate of aromatic hydrocarbons with summary content of aromatics at least 95 wt %. In other embodiments of invention, products leaving second reactor are separated into gas and high-octane fraction. The latter is combined with straight-run gasoline fraction distilled from initial hydrocarbon feedstock.

EFFECT: increased average production of liquid products.
