Catalytic reactor with quenching device provided with tangential injection of a quenching fluid

摘要

The catalytic reactor: comprises an enclosure (1) containing two solid catalyst beds (2, 11) separated by an intermediate zone comprising a collecting plate (6) co-operating with a quenching box (7) placed under the collecting plate; and an injector channel that is provided for a hardening fluid and placed in a collection space (4) located in the intermediate zone at top of the collecting plate and comprises a pipe comprising a single opening emerging within the space, where the opening is located at the end of the pipe. A maximum spacing between the enclosure and the channel is 0-40 cm. The catalytic reactor: comprises an enclosure (1) containing two solid catalyst beds (2, 11) separated by an intermediate zone comprising a collecting plate (6) co-operating with a quenching box (7) placed under the collecting plate; and an injector channel that is provided for a hardening fluid and placed in a collection space (4) located in the intermediate zone at top of the collecting plate and comprises a pipe comprising a single opening emerging within the collection space, where the opening is located at the end of the pipe. A maximum spacing between the enclosure and the injector channel is 0-40 cm. The end of the injector channel includes a tubular portion provided to inject the hardening fluid into the collection space according to a horizontal direction and forming an angle of -10[deg] and +10[deg] compared to a tangent direction with a wall of the enclosure on a level of the tubular portion. The channel emerges with the wall of the enclosure to inject the fluid according to a direction forming an angle of -10[deg] and +10[deg] compared to the horizontal direction, forms a tube length of 5-50 cm measured within the collection space, and is placed at a distance of lower than 30 cm of the enclosure and at a distance of lower than 20 cm of the collection plate. The reactor further comprises a gas and liquid distributor plate placed under the quenching box, and a perforated plate placed between the quenching box and the distributor plate. An independent claim is included for a method for application of a reactor.
