Abstract: PROBLEM TO BE SOLVED: To provide a reactor in which a hot spot is difficult to occur in a catalyst packed inside the reactor, having little pressure drop when fluid reaction mixtures pass through the catalyst, and in which the heterogeneous catalyst is packed. SOLUTION: A fixed-bed reactor is described for carrying out reactions of fluid reaction mixtures in the presence of a particulate heterogeneous catalyst having a structured packing which forms interstices in the reactor interior, in which the quotient of the hydraulic diameter for the fluid flow through the structured packing and the equivalent diameter of the catalyst particles is in the range from 2 to 20, preferably in the range from 5 to 10, to such an extent that the catalyst particles are introduced into the interstices, loosely distributed and discharged under the action of gravity.

Abstract: PROBLEM TO BE SOLVED: To provide a distillation column having high separation efficiency, in which the vapor amount is made constant all over the column including a feed section and a side steam take-off section.
SOLUTION: Partition walls DW are arranged substantially along the longitudinal direction of the distillation column so that the inside of the distillation column is divided into an upper zone 2 and a lower zone 4 of the feed section, an upper zone 3 and a lower zone 5 of the side stream take-off section, an upper common column section 1 and a lower common column section 6. A feeding mixture to be separated between the zones 2 and 4 of the feed section is in a wholly or partially vaporized state and/or the side stream to be taken off from the zones 3 and 5 of the side stream take-off section is in a wholly or partially vaporized state.

Abstract: Columna para la puesta en práctica de destilaciones reactivas en presencia de un catalizador heterogéneo en forma de partículas, con una empaquetadura formada por chapas de empaquetadura que forman cavidades en el espacio interior de la columna, caracterizada porque la columna presenta primera y segunda zona parcial, que están dispuestas alternantemente, y se diferencian en la superficie específica de las chapas de empaquetadura, de tal manera que en las primeras zonas parciales el cociente de diámetro hidráulico para la corriente gaseosa a través de la empaquetadura y el diámetro equivalente de partículas de catalizador se sitúa en el intervalo de 2 a 20, preferentemente en el intervalo de 5 a 10, de modo que las partículas de catalizador se pueden introducir en las cavidades, distribuir y descargar sueltas bajo acción de la fuerza de gravedad, y porque en las segundas zonas parciales el cociente de diámetro hidráulico para la corriente gaseosa a través de la empaquetadura y el diámetro equivalente de partículas de catalizador es menor que 1, y porque en las segundas zonas parciales no se introducen partículas de catalizador.

Abstract: Fixed bed reactor comprises a structured packing (1) forming intermediate chambers (3) inside the reactor. The quotient of the hydraulic diameter for the fluid stream through the packing and the equivalent diameter of catalyst particles (4) is in the region of 2-20, preferably 5-10. The catalyst particles are introduced into the intermediate chambers under the action of gravity, loosely distributed and removed. Preferred Features: The structured packing has a cross-channel structure, and comprises packing sheets for insertion along the longitudinal axis of the reactor. The packing has a reduced flow resistance on its surface.
