REACTOR FOR COMBINED PROCESSING OF HYDROCARBON FRACTIONS AND OXYGENATES ON ZEOLITE CATALYST AND APPARATUS FOR PRODUCING GASOLINES OR CONCENTRATES OF AROMATIC COMPOUNDS WITH SUCH REACTOR Russian patent published in 2025 - IPC C10G35/95 C10G3/00 B01J19/24 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: invention relates to oil refining and petrochemical industry. Invention relates to a plant for production of gasolines or concentrates of aromatic compounds, which includes three feed lines of mixtures of initial hydrocarbon material or hydrocarbon material and oxygenate or hydrocarbon material and water, a reactor unit, implemented in the form of a multi-shelf reactor, including three reaction zones, heat exchangers, furnace, process lines and shutoff and control valves for supply of each type of raw material to each reaction zone. Outlet of the first reaction zone is connected to the inlet to the second reaction zone and to the first intermediate separator, and the outlet from the second reaction zone is connected to the inlet to the third reaction zone and to the second intermediate separator. First and second separators have liquid phase outlets from below, and from above the outlets for the gas phase with shutoff and control valves, which regulate the flow rate of the non-condensed gas phase. Output of the reaction product from the third reaction zone is connected countercurrently to the raw material flows through heat exchangers with a cooler and a separator of reaction products. Invention also relates to a reactor for producing gasolines or concentrates of aromatic compounds.

EFFECT: simplified control of the process of obtaining the oil refining product.
