Xylenes Production

Xylenes production

ExxonMobil Chemical has led the development and application of leading-edge technologies for xylenes and benzene production since the discovery of ZSM-5 in the late 1960s. Technologies for paraxylene and benzene production include: selective and non-selective toluene disproportionation, xylene isomerization, heavy aromatics transalkylation, selective toluene alkylation with methanol, and aromatics treatment.

For customers interested in constructing a complete grassroots complex, ExxonMobil’s alliance with Axens S.A. offers all of the technologies required to meet your needs.

Our process

Our applications

  • Toluene selective alkylation with methanol (EMTAM℠)

    The EMTAM℠ process is a breakthrough technology that maximizes production of valuable paraxylene while lowering feed and energy costs.

  • Vapor phase xylene isomerization (XyMax℠-2)

    XyMax-2 isomerization produces paraxylene and/or orthoxylene from feedstocks rich in C8 aromatics.

  • Heavy aromatics transalkylation (TransPlus℠ 5)

    A low-cost, high conversion solution to upgrade C9+ heavy aromatics and tolulene/benzene to higher-value mixed xylenes and high-purity benzene.

  • Liquid phase xylene isomerization (LPI)

    LPI process technology is the latest generation of liquid phase isomerization technology offering significant energy savings and ultra-low xylene losses.

  • Selective toluene disproportionation (PxMax℠)

    PxMax offers improved yields, excellent stability, ease of operation and extremely long catalyst cycles.

  • Aromatics treatment (Olgone℠)

    Olgone process technology is designed to significantly extend the cycle length of existing clay treaters, reducing the amount of spent clay generated when producing xylenes.

  • Toluene disproportionation (MTDP-3)

    MTDP-3 is designed to process toluene and limited amounts of C9 aromatics, and can allow for inexpensive debottlenecking of existing toluene disproportionation (TDP) facilities.
