Claims21
A process for purifying a contaminant-containing stream comprising the steps:
- a. Providing a filtering medium composition comprising granular particles ranging in size from about 0.001 mm to about 15 mm, or one or more shaped filter bodies, and comprising a mixture of 1) the oxides of copper, 2) one or more of the oxides of magnesium, calcium, strontium, and barium, and 3) one or more of the oxides of aluminum, boron, cerium, cesium, dysprosium, erbium, europium, gadolinium, gallium, hafnium, holmium, indium, iron, lanthanum, lithium, lutetium, manganese, molybdenum, neodymium, praseodymium, samarium, silicon, silver, titanium, vanadium, ytterbium, yttrium, zinc, and zirconium,
- i. Wherein the fraction of copper oxides is at least 50% by total mass, and
- ii. Wherein the atom ratio of the sum of magnesium, calcium, strontium, and barium to that of copper is at least equal to 0.02,
- b. Passing a contaminant-containing fluid stream through the fluid filter materials, thereby removing the contaminants and purifying the fluid stream, and
- c. Recovering the purified fluid stream.
A process for purifying an aqueous stream, comprising:
- a. placing a fluid filter housing comprising a filter cartridge in a fluid line, wherein the filter cartridge is packed with a filtering medium composition of granular particles ranging in size from about 0.001 mm to about 15 mm, or one or more shaped filter bodies, and comprising a mixture of 1) the oxides of copper, 2) one or more of the oxides of magnesium, calcium, strontium, and barium, and 3) one or more of the oxides of aluminum, boron, cerium, cesium, dysprosium, erbium, europium, gadolinium, gallium, hafnium, holmium, indium, iron, lanthanum, lithium, lutetium, manganese, molybdenum, neodymium, praseodymium, samarium, silicon, silver, titanium, vanadium, ytterbium, yttrium, zinc, and zirconium,
- i. wherein oxides of copper comprise at least 50% by total mass of the filtering medium composition, and
- ii. wherein the atom ratio of the sum of magnesium, calcium, strontium, and barium to that of copper in the filtering medium composition is at least equal to 0.02,
- b. passing the aqueous stream through the fluid filter cartridge to remove all contaminants from the aqueous stream, and
- c. recovering the purified aqueous stream.
A process for purification of a gas stream comprising hydrogen, methane, light hydrocarbons, nitrogen, helium, carbon monoxide, argon, natural gas, or other gas, or some mixture thereof, comprising the steps:
- a. Providing a filtering medium composition comprising granular particles ranging in size from about 0.001 mm to about 15 mm, or one or more shaped filter bodies, and comprising a mixture of 1) the oxides of copper, 2) one or more of the oxides of magnesium, calcium, strontium, and barium, and 3) one or more of the oxides of aluminum, boron, cerium, cesium, dysprosium, erbium, europium, gadolinium, gallium, hafnium, holmium, indium, iron, lanthanum, lithium, lutetium, manganese, molybdenum, neodymium, praseodymium, samarium, silicon, silver, titanium, vanadium, ytterbium, yttrium, zinc, and zirconium,
- i. Wherein the fraction of copper oxides is at least 50% by total mass, and
- ii. Wherein the atom ratio of the sum of magnesium, calcium, strontium, and barium to that of copper is at least equal to 0.02,
- b. Optionally cooling the gas stream by heat exchange,
- c. Optionally scrubbing the gas stream with water,
- d. Passing the gas stream through the fluid filter materials, thereby removing any contaminants and purifying the fluid stream, and
- e. Recovering the purified gas stream.
A process for regenerating filtering media composition comprising:
- a. Providing filtering media composition of granular particles ranging in size from about 0.001 mm to about 15 mm and comprising a mixture of 1) the oxides of copper, 2) one or more of the oxides of magnesium, calcium, strontium, and barium, and 3) one or more of the oxides of aluminum, boron, cerium, cesium, dysprosium, erbium, europium, gadolinium, gallium, hafnium, holmium, indium, iron, lanthanum, lithium, lutetium, manganese, molybdenum, neodymium, praseodymium, samarium, silicon, silver, titanium, vanadium, ytterbium, yttrium, zinc, and zirconium,
- i. Wherein the fraction of copper oxides is at least 50% by total mass,
- ii. Wherein the atom ratio of the sum of magnesium, calcium, strontium, and barium to that of copper is 0.02 or higher, and
- iii. Wherein the filtering media have been used to remove contaminants from one or more fluid streams, and
- b. Combusting the material in air or other oxygen-containing gas.
A filtering medium composition of granular particles ranging in size from about 0.001 mm to about 15 mm and comprising a mixture of 1) the oxides of copper, 2) one or more of the oxides of magnesium, calcium, strontium, and barium, and 3) one or more of the oxides of aluminum, boron, cerium, cesium, dysprosium, erbium, europium, gadolinium, gallium, hafnium, holmium, indium, iron, lanthanum, lithium, lutetium, manganese, molybdenum, neodymium, praseodymium, samarium, silicon, silver, titanium, vanadium, ytterbium, yttrium, zinc, and zirconium,
- a. Wherein the fraction of copper oxides is at least 50% by total mass, and
- b. Wherein the atom ratio of the sum of magnesium, calcium, strontium, and barium to that of copper is at least equal to 0.02.
