Abstract
The present invention relates to a bound metal oxide particle comprised of metal oxide and a binder, with the binder preferably being a starch solution. The present invention also relates to a method for forming a bound metal oxide particle, with the preferred method including extruding and pelletizing a metal oxide and binder composition to form pelletized metal oxide particles.
Claims21
A bound metal oxide composition for removing contaminants from fluids, wherein said bound metal oxide composition consists of:
- a. at least one metal oxide of the formula MexOy, with Me selected from the group consisting of periodic table row 4, 5, 6 and 7 metals, with x equal to between 1 and 3, and y equal to between 1 and 4 and hydrated forms of said metal oxide;
- and,
- b. an organic hydrophobic binder, with said bound metal oxide composition having a crush strength equal to at least 1.0 Kg, said bound metal oxide composition can retain an average amount of contaminant equal to at least 10% by weight of said bound metal oxide composition.
A method for forming a bound metal oxide having a crush strength of at least 1.0 Kg, a diameter ranging between about 3 mm and 20 mm, and capable of holding an amount of contaminant equal to at least 10% by weight of said metal oxide, said method consisting of:
- a. mixing an amount of metal oxide having a particle size ranging between 0.1 microns and 100 microns and of the formula MexOy with an amount of organic hydrophobic binder to form a metal oxide mixture, wherein Me is selected from the group consisting of periodic table row 4, 5, 6 or 7 metals, x is equal to between 1 and 3, and y is equal to between 1 and 4 and hydrated forms of said metal oxide;
- and
- b. compressing said metal oxide mixture to produce said bound metal oxide.
