CC Regeneration

The Continuous Catalyst Regeneration (CCR) process is part of a process used in the petroleum and petrochemical industries, which produces aromatics from naphthenes and paraffins commonly used as motor fuel.

In this process, hydrotreated naptha is combined with recycled hydrogen gas, heated to the desired reaction temperature (496 to 524°C) and sent through a series of reactors (vertical or side by side). Because the reaction is endothermic, interstage heaters are required between each reactor section to attain the required reaction temperature. In order to attain the desired reactions and high product yield, a metal catalyst such as platinum is used. The catalyst moves from reactor to reactor and the feed mixture flows radially across the catalyst beds.
