Regeneration tower for continuous catalytic reforming process

A catalyst regeneration tower comprising:

• a burn zone comprising:
• a cylindrical section having an inner screen and an outer screen forming an annular catalyst bed therebetween, wherein the inner screen comprises punch plate, or slotted plate, and wherein the cylindrical section has a bed length in a range of 12 to 120 cm;
• a first portion of a conical section having an outer screen and a tapered inner screen forming a catalyst bed therebetween, the conical section positioned below the cylindrical section, the annular catalyst bed connected to the catalyst bed in the conical section;
• a reheat zone comprising a second portion of the conical section below the burn zone;
• a tertiary screen in the conical section covering an opening defined by the tapered inner screen and wherein the tertiary screen comprises wire mesh, profile wire screen, perforate plate, punch plate, or slotted plate, wherein the tertiary screen is at a bottom of the burn zone or in the reheat zone;
• a chlorination zone below the burn zone;
• a drying zone below the chlorination zone;
• a cooling zone below the drying zone;
• a housing containing the burn zone, the chlorination zone, the drying zone, and the cooling zone.

A catalyst regeneration tower comprising:

• a cylindrical section having an inner screen and an outer screen forming an annular catalyst bed therebetween, wherein the inner screen has a first side facing the outer screen and a second side facing a center of the cylindrical section, and further comprising a secondary screen adjacent to the second side of the inner screen and wherein the secondary screen comprises wire mesh, and wherein the cylindrical section has a bed length in a range of 12 to 120 cm;
• a conical section having an outer screen and a tapered inner screen forming a catalyst bed therebetween, the conical section positioned below the cylindrical section, the annular catalyst bed connected to the catalyst bed in the conical section;
• a tertiary screen in the conical section covering an opening defined by the tapered inner screen and wherein the tertiary screen comprises wire mesh, profile wire screen, perforate plate, punch plate, or slotted plate;
• and
• a housing containing the cylindrical section and the conical section.
