ZSM-23 Zeolite Catalyst | High-Performance Catalyst for Dewaxing & Selective Hydrocracking | Supplier

1. Product Introduction & Core Advantages

Aogochem's ZSM-23 Zeolite Catalyst is a specialized molecular sieve belonging to the MTT framework type. It is characterized by a system of narrow, one-dimensional, non-interconnecting sinusoidal pores. This constrained pore geometry provides exceptional shape selectivity, particularly for the hydroisomerization of long-chain n-paraffins. Combined with strong acidity and tailored metal functions, it achieves an outstanding balance between isomerization activity and cracking suppression, crucial for high-yield dewaxing.

ZSM-23 is a premier catalyst for lubricant base oil hydrodewaxing, where it selectively converts wax molecules into high-quality iso-paraffins, yielding premium low-pour-point base oils (Group II/III). It is equally vital for improving diesel cold flow properties. For refineries across the MENA and CIS regions, integrating ZSM-23 enhances the capability to upgrade heavy fractions into high-value lubricants and fuels, directly boosting refinery margins and product portfolio sophistication.

We engineer ZSM-23 as a robust bifunctional catalyst, integrating its unique zeolite with optimized noble metals (Pt/Pd) for maximum hydrogenation-isomerization synergy. Its high hydrothermal stability ensures long-term performance. Partnering with Aogochem provides access to this advanced catalyst technology, dedicated technical support for hydroprocessing applications, and a reliable supply chain committed to the growth of the refining sector in the MENA and CIS markets.

2. Technical Specifications & Performance Data

ZSM-23’s defining feature is its pore structure, engineered for selective hydroconversion. Aogochem customizes formulations for specific process goals.

3. Primary Application Industries

ZSM-23 is a cornerstone catalyst for modern fuel and lubricant upgrading, addressing critical product quality specifications.

• Lube Base Oil Hydrodewaxing (Primary Application): ZSM-23 is extensively used in catalytic dewaxing processes to produce high-VI, low-pour-point Group II and Group III lubricant base oils. Its pore structure is highly effective at isomerizing the long-chain n-paraffins (waxes) present in hydrocracked or solvent-refined feeds, significantly lowering the pour point while maximizing the yield of valuable base oil.

• Middle Distillate Dewaxing (Diesel & Jet Fuel): Applied to improve the cold flow properties (Cloud Point, Pour Point) of diesel and the freeze point of jet fuel. By selectively isomerizing linear paraffins in these streams, it enables refineries to meet stringent seasonal specifications without diluting the product with flow improvers.

• Selective Hydrocracking: While renowned for isomerization, its acidity and pore structure can also be leveraged in mild hydrocracking applications to selectively crack heavy molecules into desired middle distillate ranges, often with favorable product qualities.

4. Why Partner with Aogochem for ZSM-23 Catalyst?

Aogochem delivers catalyst solutions that translate complex material science into tangible process improvements.

• Mastery of Sinusoidal Pore Chemistry: Our expertise lies in optimizing the synthesis and modification of MTT-framework zeolites to exploit the unique diffusion and transition-state selectivity offered by its sinusoidal channels, a key differentiator from other 1D zeolites.

• Precision Bifunctional Design: We excel at the precise integration of the ZSM-23 component with the hydrogenation function and matrix. This careful engineering minimizes competing cracking reactions, thereby maximizing the yield of target isomerized products, which is directly correlated to unit profitability.

• Focus on Operational Economics: Our catalyst development prioritizes not just high activity, but also long catalyst life and stable performance, reducing the total cost of ownership for your hydroprocessing unit through extended run lengths and consistent product quality.

• Dedicated Hydroprocessing Support: We provide in-depth technical service from catalyst loading and activation procedures to performance monitoring and troubleshooting, ensuring our clients in the MENA and CIS regions achieve optimal results from their investment.

5. Handling & Operational Guidelines

• Loading & Presulfiding: Handle catalysts containing noble metals with care to avoid physical damage. Presulfidation is typically mandatory to properly activate the metal sites. This must be conducted according to a strict procedure provided by Aogochem, involving temperature-programmed exposure to a sulfiding agent under a hydrogen atmosphere.

• Operation: Maintain operation within the prescribed temperature, pressure, and hydrogen circulation rate windows. The catalyst's exceptional selectivity is sensitive to operating conditions; deviations can shift the product slate towards less desirable cracking products. Monitor cold flow properties of the product closely.

• Regeneration & Reuse: Upon deactivation (mainly by coke deposition), catalyst regeneration via controlled coke burn-off is possible. This is a specialized service often performed ex-situ. Aogochem can provide guidance and support for evaluating regeneration potential and procedures.

• Storage & Safety: Store in a dry, sealed container in a cool, well-ventilated area. Reduced forms of the catalyst may be pyrophoric. Always use appropriate PPE and handle in accordance with the Material Safety Data Sheet (MSDS/SDS), particularly regarding exposure to air after reduction.
