Product description

USY molecular sieve specifically refers to Y-type molecular sieve with ultra-stabilized framework structure prepared by hydrothermal dealumination after ultra-stable treatment, and its framework is relatively high in silica and aluminum. H-USY is prepared USY molecular sieve after ammonium exchange roasting, etc. Process system. USY molecular sieves are widely used in hydrocracking, isomerization, alkylation and deolefin reactions, and can also be used as VOC adsorbents and composite materials carriers.
