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...

Improved Alumina Catalyst

IntroductionAlumina has been used as a catalyst in a wide variety of industrial processes for many years. Even modest improvements in alumina catalysts can have a significant impact on efficiencies of production of a very wide variety of chemical compounds. There is a continuing commercial need for new tailored alumina catalysts that can more efficiently...

Hydrophobic Mesoporous Silica Composition

IntroductionThere is a need for improvements in the preparation of porous materials that are active for binding metals from solution on an industrial scale. The materials have the composition of organic-inorganic metal oxides and prior art is difficult to synthesize or to achieve ideal porosity for metal binding.Description of TechnologyThis technology...
