ZSM-11 Zeolite Catalyst | Advanced Catalyst for Hydrocracking & Selective Isomerization | Supplier for MENA & CIS

1. Product Introduction & Core Advantages

Aogochem ZSM-11 Zeolite Catalyst is an advanced, high-silica molecular sieve belonging to the pentasil family, distinguished by its unique MEL framework structure. While closely related to the renowned ZSM-5 (MFI framework), ZSM-11 possesses a two-dimensional pore system consisting of intersecting straight channels, offering distinct diffusion pathways and catalytic properties. This architecture, combined with its strong acidity and exceptional thermal/hydrothermal stability, makes ZSM-11 a superior catalyst for hydrocarbon conversion reactions requiring precise selectivity, particularly towards middle distillates and specific aromatic isomers.

The core advantage of ZSM-11 lies in its optimized pore geometry and acidity, which can be finely tuned by Aogochem. This allows for enhanced selectivity in reactions where molecular shape and diffusion rates are critical. For instance, in hydrocracking, ZSM-11 can be formulated to favor the production of high-value diesel and jet fuel range components over lighter gases. Its performance in xylene isomerization is also notable, where it effectively converts mixed xylenes into high-demand para-xylene with excellent yield and stability, serving as a competitive alternative or complement to other catalysts.

2. Technical Specifications & Performance Data

Aogochem's ZSM-11 catalysts are engineered with customizable properties to meet specific process requirements. The table below outlines key characteristics of our standard formulations.

3. Primary Application Industries

ZSM-11's unique properties make it a valuable catalyst in several key refining and petrochemical processes, aligning with the complex and integrated operations prevalent in the MENA and CIS regions.

• Hydrocracking: ZSM-11 is highly effective as a catalyst component in mild to moderate hydrocracking processes. Its pore structure and acidity can be tuned to selectively crack heavy gas oils and vacuum gas oils into desirable middle distillates (diesel, kerosene) while minimizing excessive production of light gases (C1-C4) and naphtha, thereby maximizing the yield of high-value transportation fuels.

• Xylene Isomerization: The catalyst plays a crucial role in aromatic complexes for producing para-xylene (PX), a key raw material for polyester. ZSM-11 efficiently catalyzes the isomerization of meta- and ortho-xylene to near-equilibrium mixtures rich in para-xylene, offering an attractive balance of activity, selectivity, and catalyst life.

• Other Petrochemical Processes: Its strong acidity and shape selectivity make it suitable for other acid-catalyzed reactions such as alkylation, disproportionation, and the conversion of light olefins or paraffins to higher-value hydrocarbons. It can serve as a specialized catalyst or co-catalyst in various upgrading units.

5. Handling & Operational Guidelines

• Loading & Activation: For fixed-bed reactors, follow standard catalyst loading procedures to ensure uniform packing and avoid channeling. Pre-treatment or activation steps (e.g., calcination, sulfidation for hydrocracking) are often required and must be performed according to the specific procedure provided by Aogochem for your catalyst formulation.

• Operation & Regeneration: Operate within the recommended temperature, pressure, and space velocity windows to achieve optimal performance and catalyst life. Spent catalyst can typically be regenerated ex-situ via controlled coke burn-off to restore activity. Consult our technical team for a detailed regeneration protocol.

• Storage: Store in a dry, cool, and well-ventilated area in sealed, original packaging. Protect from exposure to moisture, contaminants, and extreme temperatures to preserve catalyst quality.

• Safety: Handle as a fine solid material. Use appropriate personal protective equipment (PPE) including gloves, protective clothing, dust masks, and safety glasses to prevent irritation. Always refer to the provided Material Safety Data Sheet (MSDS/ SDS) for comprehensive safety and handling instructions.
