Catalytic Reforming Process by Axens
Upgrade various types of naphtha to produce high-octane reformate, BTX and LPG.
Two different designs are offered. One design is conventional where the catalyst is regenerated in place at the end of each cycle. Operating normally in a pressure range of 12 to 25 kg /cm2 (170 to 350 psig) and with low pressure drop in the hydrogen loop, the product is 90 to 100 RONC. With their higher selectivity, trimetallic catalysts RG582 and RG682 make an excellent catalyst replacement for semi-regenerative reformers.
The second, the advanced Octanizing process, uses continuous catalyst regeneration allowing operating pressures as low as 3.5 kg /cm2 (50 psig). This is made possible by smooth-flowing moving bed reactors (1–3) which use a highly stable and selective catalyst suitable for continuous regeneration (4). Main features of Axens’ regenerative technology are:
• Side-by-side reactor arrangement, which is very easy to erect and consequently leads to low investment cost.
• The RegenC-2 catalyst regeneration system featuring the dry burn loop, completely restores the catalyst activity while maintaining its specific area for more than 600 cycles.
Finally, with the new CR 601 (gasoline mode) and AR 701 (aromatics production) catalysts specifically developed for ultra-low operating pressure and the very effective catalyst regeneration system, refiners operating Octanizing or Aromizing processes can obtain the highest hydrogen, C5+ and aromatics yields over the entire catalyst life.
