Catalytic reforming continuous catalyst

The name is derived from platinum-reforming. While platinum was the first catalyst to be developed for catalytic reforming, other catalysts and related processes have subsequently been developed over the past 60 years. Continuous catalytic regeneration or CCR platforming is a widely used continuous version of the process. 

The process consists of a reactor section, continuous catalyst regeneration unit (CCR), and product recovery section. Stacked radial-flow reactors are used to minimize pressure drop and to facilitate catalyst recirculation to and from the CCR. The reactor feed consists solely of LPG plus the recycle of unconverted feed components no hydrogen is recycled. The liquid product contains about 92 wt% benzene, toluene, and xylenes (BTX) (Figure 6-7), with a balance of Cg aromatics and a low nonaromatic content. Therefore, the product could be used directly for the recovery of benzene by fractional distillation (without the extraction step needed in catalytic reforming). 

Fluid Hydroforming An early catalytic reforming process in which the catalyst was used in a continuously regenerated fluidized bed. Developed by the MW Kellogg Company. 

Hon (Informing A continuous catalytic reforming process for producing aromatic concentrates and high-octane gasoline. It used a fixed bed of a platinum catalyst. Developed in the 1950s by the Houdiy Process Corporation. 

Dualforming A process that enables a petroleum refiner to improve the catalytic reforming step at minimal capital cost. A new reactor with continuous catalyst recirculation is integrated into the existing reactor train. Developed and offered by Axens.
