Aogochem's ZSM-48 Zeolite Catalyst is a specialized molecular sieve with *MRE topology, featuring a one-dimensional pore system composed of 10-membered rings (5.6 x 5.6 Å)-7. This linear, uniform channel structure imparts exceptional shape selectivity, particularly for the hydroisomerization of linear and slightly branched paraffins-2. Its strong acidity and tunable silica-alumina ratio (from ~25 to over 300) allow for precise catalytic control, making it a cornerstone for high-selectivity upgrading processes-5-7.
ZSM-48 is a premier catalyst for catalytic dewaxing (isodewaxing) to produce high-Viscosity Index (VI), low-pour-point Group II/III lubricant base oils-2-10. It is equally critical for improving the cold flow properties of diesel and jet fuel-2. For refineries and lube plants in the MENA and CIS regions, ZSM-48 transforms waxy feedstocks into high-value, low-pour-point products, maximizing asset value and enabling the production of premium lubricants and winter-grade fuels from local resources.
We supply ZSM-48 catalysts, including low silica-alumina ratio (e.g., 25-50) variants with enhanced acidity for higher activity-8. Engineered into robust bifunctional formulations with optimized noble metals (Pt/Pd), they deliver outstanding isomerization selectivity and stability-7. Partnering with Aogochem provides access to advanced catalyst technology, deep expertise in hydroprocessing, and dedicated support to optimize your dewaxing unit's yield and profitability.
The performance of ZSM-48 is defined by its unique 1D pore structure and adjustable acidity. Aogochem offers both standard and customized low-Si/Al ratio formulations-8.
| Parameter | Unit | Typical Specification / Description | Importance / Notes |
|---|---|---|---|
| Framework Type | - | *MRE | Defines the one-dimensional, 10-membered ring straight channel system (5.6 x 5.6 Å), key for shape-selective isomerization-7. |
| SiO₂/Al₂O₃ Molar Ratio | - | 25 to 300+ (Wide Customizable Range) | Lower ratios (e.g., 25-50) increase acid site density and activity-7-8. Higher ratios enhance hydrothermal stability. A key differentiator of our product line. |
| Typical Crystal Morphology | - | Needle-like, Rod-like | Reflects the 1D growth habit along the pore direction-1-3. |
| Primary Acid Site Strength | - | Medium Strength (e.g., ~360°C desorption peak) | Provides optimal activity for paraffin isomerization without excessive cracking-3. |
| Key Performance Metric | - | High Isomerization Selectivity | Demonstrated in tests; e.g., Pt/HZSM-48 achieved up to 72% isomer yield in n-heptane hydroisomerization-7. |
| Typical Forms | - | Powder, Extrudates (with binder) | Formulated into mechanically strong particles suitable for fixed-bed hydroprocessing reactors. |
| Thermal & Hydrothermal Stability | - | High | Maintains structure and activity under industrial hydroprocessing conditions-1. |
ZSM-48’s exceptional isomerization selectivity makes it indispensable for producing high-quality fuels and lubricants.
Lubricant Base Oil Hydrodewaxing (Isodewaxing): The primary and most valuable application. ZSM-48 selectively isomerizes long-chain n-paraffins (waxes) in feedstocks into branched isomers, dramatically lowering the pour point while maximizing the yield and Viscosity Index (VI) of the base oil-2-10. This is essential for manufacturing premium Group II and Group III lubricants.
Middle Distillate Dewaxing: Used to improve the cold flow properties (Cloud Point, Pour Point) of diesel and the freeze point of jet fuel, including promising applications in biomass-based jet fuel production-2.
Other Hydroisomerization & Aromatic Processes: Effective in the isomerization of C10+ paraffins and shows potential in xylene isomerization and toluene disproportionation reactions-2. It can also be used in composite catalysts (e.g., with Y-type zeolite) for enhanced performance in heavier feed conversions-4.
Aogochem delivers cutting-edge ZSM-48 solutions tailored to the evolving needs of the high-performance lubricant and fuel market.
Expertise in Low Si/Al Ratio Synthesis: We master the synthesis of low silica-alumina ratio (high aluminum) ZSM-48, which offers higher acid site density and enhanced catalytic activity—a key advancement over traditional high-silica forms-7-8.
Focus on Isomerization Yield & Selectivity: Our catalysts are engineered to maximize the selective isomerization of n-paraffins into valuable iso-paraffins, directly translating to higher yields of premium base oils and fuels and superior process economics for your unit.
Advanced Composite & Formulation Technology: We provide not only standard ZSM-48 but also advanced formulations, including composite molecular sieves (e.g., Y/ZSM-48) designed to tackle more complex feedstocks and reactions-4.
Technical Partnership for Value Creation: We collaborate closely with clients to select or develop the optimal ZSM-48 variant for their specific feedstock and product objectives, providing comprehensive support to ensure maximum return on investment.
Loading & Presulfiding: As a bifunctional catalyst typically containing noble metals (Pt/Pd), proper presulfidation following Aogochem's precise procedures is crucial to correctly activate the metal sites before contact with hydrocarbon feed.
Operation: Operate within the specified temperature, pressure, and hydrogen-to-oil ratio parameters. The catalyst's high isomerization selectivity is sensitive to operating conditions. Closely monitor product pour point/cloud point and isomer yield.
Regeneration: Deactivated catalyst (primarily from coke deposition) can typically be regenerated via controlled coke burn-off. For catalysts containing noble metals, this is a specialized procedure best performed ex-situ by qualified service providers in consultation with Aogochem.
Storage & Safety: Store in a dry, sealed container in a cool place. Use appropriate PPE (gloves, safety glasses) when handling fine powders. Always follow the Safety Data Sheet (SDS/MSDS) instructions, especially regarding pyrophoric risks after reduction.
