FIELD: oil industry.
SUBSTANCE: invention relates to designs of mass-exchange apparatus of periodic action and can be used in oil refining and petrochemical industry. Reaction-rectification apparatus includes a reaction vat fraction and a reaction-fractionating column with catalyst attachments connected to it by means of detachable connection. Each nozzle section is made of stainless steel, and tubular capacitors are connected to it by means of nozzles for selection of light oil fractions. Heat-sensitive elements are arranged opposite the capacitors to fix thermodynamic parameters in the catalytic section. In the reaction-rectification column the plate contact devices on which the catalyst nozzles are laid are alternated through metal spacers with empty plates for condensation of vapours formed on the surface. Reforming and isomerisation processes are carried out on the surface of the solid-phase catalyst nozzle, and a reforming process takes place in the bottom part in the presence of a solid-phase catalyst.
EFFECT: increased degree of conversion of initial hydrocarbons of oil and increased selectivity of target products, as a result of which depth of oil refining is increased.
