    摘要： Disclosed are processes for regenerating catalysts comprising at least one Group 10 metal and a microporous crystalline aluminosilicate having a having a molar ratio of Group 10 metal to Al of greater than or equal to about 0.007:1, and hydrocarbon conversion processes including such regeneration processes. In an aspect, the regeneration processes comprise an oxychlorination step comprising contacting the catalyst with a first gaseous stream comprising a chlorine source and an oxygen source under conditions effective for dispersing at least a portion of the at least one Group 10 metal on the surface of the catalyst and for producing a first Group 10 metal chlorohydrate. The processes further comprise a chlorine stripping step comprising contacting the catalyst with a second gaseous stream comprising an oxygen source, and optionally a chlorine source, under conditions effective for increasing the O/Cl ratio of the first Group 10 metal chlorohydrate to produce a second Group 10 metal chlorohydrate.

    摘要： Apparatuses and methods are provided for regenerating catalyst particles. In one embodiment, a method for regenerating catalyst particles includes passing the catalyst particles through a halogenation zone and a drying zone. The method feeds drying gas to the drying zone and passes a first portion of the drying gas from the drying zone to the halogenation zone. The method includes removing a second portion of the drying gas from the drying zone and injecting a halogen gas into the second portion of the drying gas. Further, the method includes delivering the halogen gas and the second portion of the drying gas to the halogenation zone. In the method, substantially all of the drying gas fed to the drying zone enters the halogenation zone.

    摘要： A reactor for regenerating catalyst grains comprises a vessel having an oxychlorination zone superimposed over a calcining zone having a line for introducing gas. A chamber, disposed between oxychlorination and calcining zones, comprises an internal space located between two plates which are gas tight and impervious to catalyst grains. A plurality of tubes pass through the chamber to allow catalyst to pass from oxychlorination zone to calcining zone. A plurality of means pass through the chamber to allow calcining gas to pass from calcining zone to oxychlorination zone. At least one oxychlorination gas injection line opens into the internal space of the chamber. Each means for passage of calcining gas comprises at least one orifice communicating with the chamber internal space, and a means for evacuating gas which is permeable to gas and impermeable to catalyst grains.

    摘要： A method is disclosed for decreasing the emissions of chlorine-containing species from a moving bed process for regenerating spent catalyst particles with a recycle gas stream. A recycle gas stream contacts spent catalyst particles at regeneration conditions, thereby producing a flue gas stream. The flue gas stream which contains chlorine-containing species contacts spent catalyst particles at sorption conditions. The spent catalyst particles sorb the chlorine-containing species from the flue gas stream, thereby producing the recycle gas stream. A portion of the recycle gas stream is vented from the process. This method captures and returns to the process the chlorine-containing species that would be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of the process. This method is adaptable to many processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated in a moving bed.
