C8 Aromatics Isomerization

Application The Isomar process isomerizes C8 aromatics to mixed xylenes, to maximize the recovery of paraxylene in a UOP aromatics complex. Depending on the type of catalyst used, ethylbenzene (EB) is also converted into xylenes or benzene. 

XyMax A selective process for making p-xylene and o-xylene by isomerizing C8 aromatics-rich hydrocarbon streams, using a proprietary zeolite catalyst. Developed by ExxonMobil and first used in 2000 in its refinery on Jurong Island, Singapore. Five more units have subsequently been licensed. Retrofit applications are licensed by ExxonMobil Chemical, grassroots applications by Axens. 

IFP p-Xylene Mixed xylenes Octafining isomerizes C8 aromatics to paraxylene 22 1997... 

Although commercial use of the octafining process has been to isomerize C8 aromatics, the process is equally suited to the isomerization of Co and Cm aromatics. A particularly promising application is the isomerization of mixed Co aromatics to produce pseudocumene.
