Several commercial reforming processes are available for license worldwide. A list of reforming processes with a summary of key process features is presented in Table 3. Several commercial processes are available, dominated by UOP and Axens Technologies for semiregenerative and continuous reforming. Other licensors included Houdry Division, Chevron, Engelhard, ExxonMobil, and Amoco, but none of them is currently... 

The total capacity of the semiregenerative units exceeded 5.0 million b/d while CCR units reached 3.8 million b/d. The simultaneous use of CCR technology and bimetallic catalysts has given UOP a unique position in the field of catalytic reformer process licensing. Recent catalyst formulations have improved both aromatic and reformate yields. UOP has improved the performance of the conventional platforming process by incorporating a CCR system. The process uses stacked radial-flow reactors and a CCR section to... 

Catalytic reforming is the major source of benzene and xylenes as well as of toluene. There are three basic types of processes semiregenerative, cyclic, and continuous. 

Table 3 Process conditions for semiregenerative and cyclic reforming...

The reformers are classified based on the frequency and mode of regeneration. There are four types of processes semiregenerative, nonregenerative, cyclic, and continuous catalyst regeneration (CCR).
