METHOD AND DEVICE FOR OBTAINING OF HIGH-OCTANE GASOLINE BY COMBINED PROCESSING OF HYDROCARBON FRACTIONS AND OXYGEN-CONTAINING ORGANIC RAW MATERIAL Russian patent published in 2015 - IPC C10G35/04 

FIELD: chemistry.

SUBSTANCE: hydrocarbon fractions and oxygen-containing organic raw material (oxygenate) are mixed. Obtained mixture is heated and supplied to the top of tray reactor, connected to system of cooling of reaction products inside reactor. Part of oxygenate is additionally directed directly in middle part of reactor. Catalysate from reactor is applied as heat-carrier in stabilisation column evaporator. Catalysate is cooled in first heat-exchanger and first refrigerator and supplied into separator, made with possibility of separating supplied cooled catalyst into flash gas, water and liquid hydrocarbon fraction, which after preliminary heating in second heat-exchanger is directed into stabilisation column. Flash gas is directed into main line of stabilisation gas and partially into stabilisation column. Part of stabilisation gas from upper part of stabilisation column is supplied through second refrigerator into reflux capacity, from which gas fraction is supplied into main line of stabilization gas and liquid phase - for irrigation into stabilisanion column and partially as liquefied propanebutane fraction to product warehouse.

EFFECT: increased quality of obtained product with simultaneous simplification of applied device construction.
