MCM-22
MCM-22 zeolite is a high-performance crystalline aluminosilicate catalyst first synthesized and patented in 1990 by researchers from Mobil Oil Corporation. The Structure Commission of the International Zeolite Association (IZA) officially designated its unique topology as MWW (Mobil Twenty Two) framework. This zeolite forms as a lamellar precursor that condenses into a robust three-dimensional structure during calcination, producing crystals with characteristic hexagonal morphology and the c-axis unit cell perpendicular to the crystal surface.
The exceptional catalytic performance of MWW framework zeolite stems from its dual independent pore systems. The first system consists of two-dimensional sinusoidal channels defined by 10-membered rings with internal dimensions of 4.0×5.9 Å, similar to those found in ZSM-5 zeolite. The second system comprises stacked supercages measuring 7.1×7.1×18.2 Å, accessible exclusively through 10-membered ring openings. This unique architecture enables efficient distribution of acid sites both within the internal cavities and on the external surface semi-cavities ("cups") of the crystallites.
MCM-22 zeolite for benzene alkylation is the industry standard catalyst for this critical petrochemical process. It is also widely utilized in toluene disproportionation, methane aromatization, alkane cracking, methanol-to-olefin conversion, and as a high-performance additive in fluid catalytic cracking (FCC) catalysts. Its versatile acidity and pore structure make it suitable for multiple hydrocarbon transformation reactions.
Our MCM-22 zeolite features precisely controlled pore sizes and shapes engineered during synthesis. This tailored structure enables molecular sieving effects, allowing selective adsorption and reaction of specific molecules. The result is exceptional selectivity for desired products and minimal formation of unwanted by-products, particularly in benzene alkylation processes.
YUTAI MCM-22 zeolite possesses a high density of active acid sites distributed both within the internal pore system and on the external surface semi-cavities. These acid sites provide excellent catalytic activity for cracking, isomerization, and alkylation reactions, promoting efficient conversion of reactants even under moderate operating conditions.
Our zeolite catalysts are engineered to maintain consistent performance over extended operation periods. They withstand harsh industrial conditions including high temperatures, elevated pressures, and exposure to reactive chemicals, reducing catalyst replacement frequency and ensuring uninterrupted production.
We offer MCM-22 zeolite with fully customizable surface properties. Through post-synthesis modifications such as dealumination, metal loading, and surface functionalization, we optimize catalyst performance to match your specific reaction requirements and process conditions.
