Catalytic Reforming

Catalytic reforming accounts for a large share of the world’s gasoline production and is the most important source of aromatics for the petrochemical industry. Reforming is also a major source of refinery hydrogen, the demand for which is growing rapidly as a result of escalating hydrotreatment requirements. Different Catalytic Reformer designs are offered: semi-regenerative (SRR), or continuous catalyst regeneration (CCR) catalytic reforming.

Select an application

Continuous Catalyst Regeneration (CCR) reformer design is similar to a fixed-bed semi-regenerative design with heaters between each reactor and a recycle gas compressor in order to reduce coke make. In order to ensure a continuous operation of the unit, the catalyst must move or circulate through the reactors and the regenerator so that coke is burned and the catalyst regenerated on a continuous basis. 

Process Technologies

Octanizing™ and Aromizing™

The Octanizing™ and Aromizing™ technology offers unrivaled product yields, low investment and operating costs and an exceptional on-stream factor for the production of gasoline and aromatics. Axens has an extensive experience in capacity and severity with over 130 licenses awarded worldwide.

Cyclic Reforming utilizes a swing reactor in addition to on-oil reactors and separate regeneration system to maintain continuous operation of the reaction system, while individual reactors are regenerated in the regeneration system.  

As a reactor becomes sufficiently deactivated, the swing reactor replaces it in the on-oil reactor series through a sequence of valve movements in the reaction and regeneration headers.

Hydrotreated naphtha feed is combined with hydrogen-rich recycle gas, preheated by heat exchange with the reactor effluent and then further heated in a fired heater before entering the first reactor. As the endothermic reforming reactions cool the feed and product mixture, the effluent from the first reactor must be reheated to the required reaction temperature in a fired heater before entering the second reactor, and similarly for the last reactor.
