METHOD OF PRODUCING GASOLINE COMPONENTS Russian patent published in 1998 - IPC

FIELD: gasoline production. SUBSTANCE: increased production of high-octane gasolines is accomplished by separating catalytic reforming product into middle- octane light and high-octane heavy parts. In particular, in a method of producing gasoline components involving distillation of reforming product in stabilization column operated with reflux and introducing a part of additionally heated still residue into still, tapping out fraction of low-boiling components from the top and withdrawing stable reforming product from the bottom, liquid reforming product side-cut distillate is tapped out from stripping section of column, cooled and used as middle-octane gasoline component, and still residue is used as component of high-octane gasoline. Tapping-out of liquid side distillate is maintained in dependence on octane ratio of reforming product and commercial high-octane gasoline produced from still residue. EFFECT: improved utilizing high-quality gasoline components. 1 dwg, 1 tbl
