MCM-22
In the dynamic field of chemical synthesis, our zeolites stand out as advanced catalysts that can revolutionize reaction processes. Catalysts are essential in chemical industries as they speed up reactions, improve product selectivity, and reduce energy consumption. Zeolites, with their well - defined pore structures and adjustable surface properties, offer unique advantages as catalysts or catalyst supports. Our zeolite - based catalyst products are engineered to meet the specific needs of various chemical reactions, from petrochemical refining to the production of fine chemicals, providing efficient and sustainable solutions for modern chemical manufacturing.
• Tailored Pore Structure for Selective Catalysis: The pore size and shape of our zeolites can be precisely controlled during synthesis. This tailored pore structure allows for selective adsorption and reaction of specific molecules, enabling the production of desired products with high selectivity and minimizing the formation of unwanted by - products.
• High Acid - Site Density and Activity: Many of our zeolite catalysts possess a high density of active acid sites on their surface. These acid sites are crucial for catalyzing reactions such as cracking, isomerization, and alkylation in the petrochemical industry, providing excellent catalytic activity and promoting efficient conversion of reactants.
• Stability and Longevity: Our zeolite catalysts are designed to maintain their catalytic performance over extended periods of operation. They can withstand harsh reaction conditions, including high temperatures, pressures, and the presence of reactive chemicals, reducing the frequency of catalyst replacement and ensuring consistent production quality.
• Customizable Surface Chemistry: We offer zeolite catalysts with customizable surface chemistries. By modifying the surface properties, such as introducing different functional groups or metals, we can optimize the catalyst's performance for specific chemical reactions, meeting the diverse requirements of our customers.
• Enhanced Reaction Efficiency: Our zeolite catalysts can significantly increase the reaction rates and conversion efficiencies in chemical synthesis processes. This leads to higher productivity, shorter production cycles, and lower production costs for chemical manufacturers.
• Improved Product Quality: The high selectivity of our zeolite catalysts ensures the production of high - quality products with fewer impurities. This is particularly important in the production of fine chemicals and specialty products, where product purity is of utmost importance.
• Sustainable Chemical Processes: By reducing energy consumption and minimizing the formation of unwanted by - products, our zeolite - based catalysts contribute to more sustainable chemical manufacturing. They help chemical companies meet environmental and sustainability goals while maintaining economic viability.
• Q: How do I determine the most suitable zeolite catalyst for my chemical reaction?
A: Factors such as the type of reaction (e.g., cracking, oxidation), reaction conditions (temperature, pressure, reactant concentration), and desired product selectivity need to be considered. Our team of experts can work with you to analyze your specific reaction requirements and recommend the most appropriate zeolite catalyst.
• Q: What is the typical lifespan of a zeolite catalyst?
A: The lifespan of a zeolite catalyst depends on the reaction conditions and the nature of the reactants. In general, under proper operating conditions, our zeolite catalysts can last from several months to several years. Regular monitoring of catalyst performance can help determine when regeneration or replacement is needed.
• Q: Can the performance of zeolite catalysts be improved over time?
A: In some cases, through post - synthesis modification techniques such as dealumination, metal loading, or surface functionalization, the performance of zeolite catalysts can be further enhanced. Our research and development team can provide guidance on such modification methods to optimize catalyst performance for specific applications.
MCM-22 was first synthesized and patented in 1990 by researchers from Mobil Oil Corporation and the Structure Commission of the International Zeolite Association (IZA) designated this peculiar topology as MWW (Mobil Twenty Two). This zeolite crystallizes as a lamellar precursor which condenses to a full three-dimensional structure under calcination, with crystals having hexagonal morphology and axis c- unit cell perpendicular to the surface.
MCM-22 structure consists of two independent pore systems: one of these systems consists of two-dimensional sinusoidal channels defined by 10-membered rings, whose internal diameter is 4.0 x 5.9 Å, similar to those found in zeolite ZSM-5; and the other channel system is formed by stacking supercages of 7.1 x 7.1 x 18.2 Å, accessible through 10 member rings. This peculiar porous systems allowed an efficient distribution of the acid sites on the external surface as in the zeolite cavities.
The zeolite MCM-22 is widely used in various catalytic reactions such as disproportionation of toluene, aromatization of methane, alkylation of benzene, alkane cracking reactions, methanol-to-olefin conversion, and also as an additive in FCC catalysts due to its acidity, which is not restricted to acid sites inside the porous systems, but also presents acid sites located in the semi cavities (‘‘cups’’) on the outer surface of the crystallites.
