950009: Catalytic Applications of Mesoporous Metallosilicate Molecular Sieves and Method for Their Preparation
Case ID:
TEC1995-0009
Web Published:
7/21/2014
Description:
Catalysis 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 quantities of
waste pollutants that are extremely difficult to dispose of and too expensive to
recycle.
Description
This technology can catalytically oxidize or
hydroxylate organic compounds within its mesoporous metallosilicate material.
The molecular sieve is comprised of a transition-metal-substituted-silicate and
has larger pores, which can more aptly support catalytic peroxide oxidation of
larger substituted aromatic compounds.
The porous material is prepared by
a neutral templating process, and the pore size is predetermined by the
appropriate neutral template (selected chemicals). The process includes
preparing a neutral precursor solution (alkoxides) and aging it in the presence
of a neutral, or non-ionic template solution. Typically, one would react an aged
silicon (or metal) alkoxide solution with a template solution, recover the
template agent, and calcine (heat to dry or decompose) the product to yield the
oxide form.
Benefits
- Faster
catalytic oxidation: Small mesopores provide for rapid peroxide
hydroxylation of benzene and oxidation of substituted aromatics compared to
slower kinetic diameters of conventional, smaller micropores.
- Lowers
costs: The templating agent can be recovered and recycled.
- Integrable: Uses relatively mild conditions and
conventional processing steps.
Applications
Most any industrial scale for catalytic oxidation
of large molecules and in treating waste water, sludge, industrial waste, or in
chemical synthesis of petroleum and petrochemicals.
