INSTALLATION FOR CATALYTIC PRODUCTION OF HIGH-OCTANE GASOLINE FRACTIONS AND AROMATIC HYDROCARBONS Russian patent published in 1997 - IPC

FIELD: petrochemical processes and equipment. SUBSTANCE: invention relates to producing high-octane gasoline fractions and aromatic C₆-C₁₀-hydrocarbons via catalytically processing organic raw material based on hydrocarbons, oxygen- containing compounds, or their mixtures. Installation has operationally interconnected rectification columns, separators, heat exchange, capacity, and pumping apparatuses, and reactor units. Reactor unit constitutes, combined by chimney flue and installed successively in direction of gas heat carrier travel, heat generator and shell-and-tube heat exchange apparatus. To improve temperature control in conditions when catalyst is immersed into tube space of reactor in different process steps proceeding with different reaction temperature effects (including both exothermic and endothermic ones), gas heat carrier with predetermined temperature (100 to 500 C) is fed into intertubular space of reactor. Gas heat carrier is prepared by way of burning up fuel gas in heat generator followed by combining resulting high-temperature smoke fumes with air. EFFECT: improved temperature control. 2 cl, 2 dwg
