Xylene Isomerization Process by GTC Technology

GT-IsomPX is GTC’s xylene isomerization technology available in two versions: ethylbenzene (EB) isomerization and EB dealkylation. Both versions gain high ethylbenzene conversion rates while producing equilibrium mixed xylenes—meta-xylene (MX), ortho-xylene (OX) and paraxylene (PX). For an EB dealkylation type of … Continue reading

Xylene Isomerization Process by ExxonMobil

To selectively isomerize a paraxylene-depleted C8 aromatics mixture to greater than equilibrium paraxylene (PX) concentration using ExxonMobil Chemical’s XyMax and Advanced MHAI processes. Simultaneously, ethylbenzene (EB) and non-aromatics in the feed are converted to benzene and light paraffins, respectively. Conversion … Continue reading
