Isoforming.The newlow-cost Interested in producing C8 Aromatics Isomers? Eliminate your platinum catalyst needs? Conserve Isoforming, afixed-bedhydroisomerization process, is fully demonstrated commercially —two units onstream, others under design. It uses an inexpensive non-noble metal catalyst Only one reactor is needed because catalyst regeneration is so infrequent.

Isoforming catalyst maintains high activity (close approach to equilibrium) over long periods, giving high yields of the desired isomer(s) throughout its life. It also makes very little gas and non-aromatic by-products, giving exceptional aromatics yields—with any C8 aromatics feed—and with very low H2 consumption.
xylenes isomerization process. Like to expand your capacity at low cost? your Aromatics? Then you should know more about Isoforming catalyst has unusually long life, and long cycle lengths between regenerations—even with difficult to isomerize feed stocks. Catalyst consumption cost is very low and onstream time is high. Simple regeneration under mild conditions restores essentially fresh catalyst activity.
Isoforming is uniquely efficient over a wide range of process conditions. So it is broadly versatile—for capacity increases and feed composition changes. It is easily adapted to expanding capacity of existing units, or to installing new capacity in surplus equipmentsuch as outmoded catalytic reformers or hydrotreaters.
