CATALYST CONTINUOUS REGENERATION REACTOR WITH GAS MIXING AND GAS DISTRIBUTION CASE IN THE OXYCHLORIZATION AREA

摘要

The continuous catalyst-regeneration reactor comprises an vessel including an oxychlorination zone (72) superimposed over a calcination zone (75) provided with a calcination gas introducing pipe, a chamber (80) that is arranged between the oxychlorination zone and the calcination zone and has an internal space located between two gas-tight plates (81, 82) and with catalyst grains, and an oxychlorination gas injecting conduit (73) opening into the internal space. The chamber is traversed by tubes for allowing the passage of catalyst grains from the oxychlorination zone to the calcination zone. The continuous catalyst-regeneration reactor comprises an vessel including an oxychlorination zone (72) superimposed over a calcination zone (75) provided with a calcination gas introducing pipe, a chamber (80) that is arranged between the oxychlorination zone and the calcination zone and has an internal space located between two gas-tight plates (81, 82) and with catalyst grains, and an oxychlorination gas injecting conduit (73) opening into the internal space. The chamber is traversed by tubes for allowing the passage of catalyst grains from the oxychlorination zone to the calcination zone and traversed by a unit for passing gas from the calcination zone to the oxychlorination zone. The unit for passing the gas comprises an orifice communicating with the internal space of the chamber, and a unit for evacuating the gas in the oxychlorination zone. The gas evacuation unit is permeable to gas and is impermeable to catalyst grains, and comprises a bubble cap, a perforated plate and a vertical tubular screen. A lower end of the tubular screen communicates with a mixing zone. An upper end of the screen is obstructed by a roof. The roof is a cone shaped roof whose vertex is directed upwardly. The oxychlorination gas injecting conduit opens into the center of the internal space at a wall of the vessel. The orifice is pierced in an upwardly orientated direction and forms an angle of 0-60[deg] with respect to a horizontal direction. A part of the tubes and the gas passage unit are integral with two plates. Independent claims are included for: (1) use of a reactor in a process for catalytic reforming of a hydrocarbon feed; and (2) a process for manufacturing the reactor.
