Fluid hydroforming

Several processes based on non-precious metal also exist. Because of high catalyst deactivation rates with these catalyst systems, they all require some form of continuous regeneration. The Fluid Hydroforming process uses fluid solids techniques to move catalyst between reactor and regenerator TCR and Hyperforming use some form of a moving bed system. 

Another approach to scale-up is the use of simplified models with key parameters or lumped coefficients found by experiments in large beds. For example, May (1959) used a large scale cold reactor model during the scale-up of the fluid hydroforming process. When using the large cold models, one must be sure that the cold model properly simulates the hydrodynamics of the real process which operates at elevated pressure and temperature. 

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. 

Apparatus. It was believed that fluid hydroforming might be a considerable improvement over the fixed-bed process. The following incentives existed for development of fluid hydroforming ... 

A flow sheet for a 3-barrel-per-day fluid hydroformer is shown as Figure 3. 

Using the fluid hydroforming pilot plant, the catalyst has also been regenerated with undiluted air by charging air to a mixture of carbonized and uncarbonized catalyst. 

A large volume of data has been compiled from the fluid hydroforming pilot plant just described. These data show definite improvement over fixed-bed hydroforming from a yield standpoint. A yield comparison has been made graphically on Figure 4 for operation on mid-continent heavy naphtha. Detailed data for this comparison are presented... 

The Standard Oil Development Co. has been active in the field of Fluid hydroforming, and the results obtained in general parallel those presented by the authors of the previous paper. Data are presented on the operation of a 50-barrel-per-day large scale Fluid hydroforming pilot plant.
