Fabrication and Characterization of Biodegradable PLA-Zeolite Composites (Includes TEC2007-0123)

IntroductionModified Atmosphere Packaging (MAP) enhances quality, extends the shelf life of perishable foods, and prevents loss revenues due to food spoilage. MAP is required because the balance and interaction of certain gases, such as carbon dioxide (CO2) and oxygen, with packaged foods contributes to either poor or high food quality. Advances in...

Catalytic Applications of Mesoporous Metallosilicate Molecular Sieves and Method for Their Preparation

IntroductionCatalysis of larger molecules would proceed more quickly with larger pores that would allow for more flux into and out of the pores. In addition, one of the most important methods for converting hydrocarbons to useful industrial chemical, intermediates, and pharmaceuticals is catalytic oxidation. Current oxidation routes result in large...

A Method for the Cost-Effective Preparation of Organofunctional, Mesostructure Molecular Sieves for Toxic, Heavy Metal Ion Trapping and Heterogeneous Catalysis

IntroductionThe ability to create lower cost, industrial strength catalytic materials with desired pore sizes and with a chemically modified surface of organic groups can improve efficiency and selectivity in existing industrial processes that modify vast volumes of fluid. Template agents (usually organic molecules or ions) direct the crystallization...

Ultrastable Porous Aluminosilicate Structures and Derived Compositions for Industrial Catalysis

IntroductionThe ability to create industrial strength catalytic materials with desired pore sizes can improve efficiency in existing industrial processes that modify vast volumes of fluid. Tunable pore sizes of interest 'in catalysis' include micropores (pore diameters up to 2 nm) and mesopores (2 to 50 nm).Description of TechnologyThis technology is...
