Recent developments in UOP Platforming are described and discussed. The concept of approach to theoretical yield is utilized to demonstrate progress of Platforming technology. Topics included in this review include: technology efficiency improvements, yield loss with octane increase and benzene management. Possible modifications available as fast generation upgrades are discussed as are the latest catalysts and the status of the second generation CCR process.
INTRODUCMON
Catalytic reforming with a platinum-containing catalyst was born at Old Dutch Refining in 1949. As a result, the refiner could control the blended octane of the refmery gasoline pool by adding high-octane reformate. Product quality could be adapted to changes in feedstock quality and product demand by altering the processing conditions on a single unit in the refinery. Since then, the refining industry has been continuously forced to adapt to changing octane and product demands, and the catalytic reformer has been instrumental in responding to these demands. The demand for change is ongoing, and, for example, UOP' , CCR' , Platform@' technology continues to respond with increased product quality and economic effectiveness.
This paper looks at the current trends in the role of the CCR Platforming unit in the refinery and the historical role that the process has played in meeting octane requirements. A concept of approach to theoretical yield is utilized to demonstrate the progress of the Platforming technology through history.
