Isomer Separation Adsorbent for Xylene and Dichlorobenzene

ZC-ISO-1 is a binder-free hydrophobic MFI zeolite adsorbent engineered for the selective separation of aromatic isomers, including xylenes, dichlorobenzenes, and dichlorotoluenes. Its binder-free MFI framework achieves crystallinity equivalent to pristine MFI crystals while delivering mechanical strength superior to conventional binder-containing zeolite adsorbents.

The adsorbent undergoes a proprietary post-synthesis treatment that imparts exceptional hydrophobicity (hydrophobicity index Hn > 7), enabling it to preferentially adsorb non-polar and weakly polar organic molecules over water. This combination of shape-selective MFI pore structure and high hydrophobicity makes ZC-ISO-1 effective both in isomer separation applications and in VOC treatment under humid conditions.

Key Features

• Binder-free MFI framework — crystallinity equal to pristine MFI zeolite
• Hydrophobicity index Hn > 7 (conventional adsorbents: Hn ~ 2)
• High mechanical strength exceeding conventional binder-containing adsorbents
• Excellent adsorption capacity for non-polar and weakly polar molecules
• Minimal catalytic activity — reduced coking and extended service life
• Low thermal effects during adsorption-desorption cycles
• Strong acid resistance and hydrothermal stability

Typical Applications

• Xylene isomer separation: Selective adsorption of para-xylene from mixed xylene streams
• Dichlorobenzene separation: Isomer-selective adsorption for industrial purification
• Dichlorotoluene separation: Shape-selective isomer separation
• VOC removal: Removal and recovery of organic vapours from humid exhaust streams
• Air purification: Treatment of organic-contaminated air in industrial environments
