Specialty Zeolite Catalysts — ZSM-11, ZSM-12, ZSM-22, ZSM-23, ZSM-35, ZSM-48 and MCM-22
ZeoCatalyst supplies a range of specialty zeolite catalyst frameworks for niche catalytic and adsorption applications where standard aluminosilicate zeolites do not provide the required pore geometry or acidity profile. Each framework is available with TDS, sample support, and batch-specific Certificate of Analysis.
February 2026 Handbook Range
| Product | Framework | SiO2/Al2O3 | BET (m2/g) | Primary Crystal Size | Main Uses |
|---|---|---|---|---|---|
| ZSM-22 | TON | 60-100 | >200 | 1000-5000 nm | Hydroisomerization, dewaxing, skeletal isomerization |
| ZSM-23 | MTT | 40-80 | >550 | 500-2000 nm | Hydroisomerization, dewaxing, cracking and adsorption |
| ZSM-35 | FER | 10-100 | >300 | 300-5000 nm | Skeletal isomerization and shape-selective catalysis |
| ZSM-48 | MRE | 60-300 | >225 | 200-4000 nm | Hydroisomerization, diesel or jet-fuel upgrading, dewaxing |
Primary crystal size is an SEM-scale crystallite measurement, not the same parameter as the laser-diffraction D50 of an agglomerated powder.
Additional Commercially Available Products
ZSM-11, ZSM-12, and MCM-22 are commercially available even though they are not included in the February 2026 handbook summary. Their published commercial powder specifications are:
| Product | Framework | SiO2/Al2O3 | BET (m2/g) | Na2O | Ion Forms | XRD Crystallinity |
|---|---|---|---|---|---|---|
| ZSM-11 | MEL | 30-100; grades 30, 60, 100 | >=300 | ≤0.05 wt% | H, Na | >=90% |
| ZSM-12 | MTW | 50-60 | >=180 | ≤0.05 wt% | H, Na | >=90% |
| MCM-22 | MWW | 25-30 | >=500 | ≤0.05 wt% | H, Na | >=90% |
Forms and Documentation
The February 2026 handbook supports Na-form, NH4-form, and H-form powders for its listed specialty frameworks. ZSM-11, ZSM-12, and MCM-22 are supplied in the H- and Na-form ranges shown above. Custom ion exchange, extrudates, and shaped bodies require technical confirmation before quotation.
Each shipment includes a batch Certificate of Analysis with data for XRD crystallinity, BET surface area, SiO₂/Al₂O₃ ratio, Na₂O content, and particle size distribution.
See the standard zeolite product pages for ZSM-5, SSZ-13, SAPO-34, Beta, Y zeolite, and other commonly used frameworks.
