Abstract
Official abstract text for this publication.
This invention is directed to novel mixed transition metal iron (II/III) catalysts for the extraction of oxygen from CO 2 and the selective reaction with organic compounds.
First claim
Opening claim text (preview).
What is claimed is: 1. A mixed metal iron (II/III) oxide catalyst for catalyzing partial oxidation of either carbon or an organic compound wherein the mixed metal iron (II/III) oxide catalyst has the formula of Fe 2 O 3 (SnO 2 ) 0.1-10 (Al 2 O 3 ) 0.1-10 . 2. The mixed metal iron (II/III) oxide catalyst of claim 1 , further comprising a support. 3. The mixed metal iron (II/III) oxide catalyst of claim 1 , further comprising an alkali or alkaline-earth element promoter. 4. The mixed metal iron (II/III) oxide catalyst of claim 2 , wherein the support is Al 2 O 3 , SiO 2 , TiO 2 , ZrO 2 or a mixture thereof. 5. The mixed metal iron (II/III) oxide catalyst of claim 1 , having the formula Fe 2 O 3 (SnO 2 ) 1.0-3.0 (Al 2 O 3 ) 1.0-3.0 . 6. The mixed metal iron (II/III) oxide catalyst of claim 4 , having the formula Fe 2 O 3 (SnO 2 ) 1.0-2.0 (Al 2 O 3 ) 0.5-5.0 . 7. The mixed metal iron (II/III) oxide catalyst of claim 4 , having the formula Fe 2 O 3 (SnO 2 ) 0.5-5.0 (Al 2 O 3 ) 1.0-3.0 . 8. The mixed metal iron (II/III) oxide catalyst of claim 6 , having the formula Fe 2 O 3 (SnO 2 ) 1.0-2.5 (Al 2 O 3 ) 1.0-2.5 . 9. The mixed metal iron (II/III) oxide catalyst of claim 6 , having the formula Fe 2 O 3 (SnO 2 ) 1.2-2.2 (Al 2 O 3 ) 1.2-2.2 . 10. A method for converting CO 2 and carbon to carbon monoxide which comprises contacting the mixed metal oxide iron (II/III) oxide catalyst of claim 1 with an appropriate CO 2 feed stream under appropriate temperature and pressure conditions. 11. The method of claim 10 , wherein the carbon, the mixed metal oxide iron (II/III) oxide catalyst, and the appropriate CO 2 feed stream are reacted together at the same time. 12. The method of claim 11 , wherein the carbon, the mixed metal oxide iron (II/III) oxide catalyst, and the appropriate CO 2 feed stream are reacted together in a fluidized bed.
