Abstract
Official abstract text for this publication.
The present invention relates to a perovskite-type strontium titanate, wherein the strontium titanate is Y- and Ni-doped and has the general formula (Sr,Y)(Ti,Ni)O 3 . A method of preparing the perovskite-type strontium titanate and its use are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A perovskite-type strontium titanate, wherein the strontium titanate is Y- and Ni-doped and has the general formula of (Sr a Y b ) d (Ti 1-c Ni c )O 3 , wherein a+b is greater than 1 and 0.8≦a≦1; 0<b≦0.2; 0<c≦0.1; and 1≦d≦1.2. 2. The perovskite-type strontium titanate of claim 1 , wherein a is from about 0.88 to about 0.98. 3. The perovskite-type strontium titanate of claim 1 , wherein b is from about 0.08 to about 0.12. 4. The perovskite-type strontium titanate of claim 1 , wherein c is from about 0.06 to about 0.08. 5. The perovskite-type strontium titanate of claim 1 having the formula (Sr 0.97 Y 0.10 )(Ti 0.94 Ni 0.06 )O 3 . 6. The perovskite-type strontium titanate of claim 1 having the formula (Sr 0.97 Y 0.10 )(Ti 0.92 Ni 0.08 )O 3 . 7. A catalyst comprising: a perovskite-type strontium titanate, wherein the strontium titanate is Y- and Ni-doped and has the general formula of (Sr a Y b ) d (Ti 1-c Ni c )O 3 , wherein a+b is greater than 1 and 0.8≦a≦1; 0<b≦0.2; 0<c≦0.1; and 1≦d≦1.2. 8. A method comprising: using a catalyst for autothermal reforming of a fuel, wherein the catalyst comprises a perovskite-type strontium titanate, wherein the strontium titanate is Y- and Ni-doped and has the general formula of (Sr a Y b ) d (Ti 1-c Ni c )O 3 , wherein a+b is greater than 1 and 0.8≦a≦1; 0<b≦0.2; 0<c≦0.1; and 1≦d≦1.2. 9. A method for autothermal reforming of a fuel, comprising contacting a catalyst with said fuel, wherein the catalyst comprises a perovskite-type strontium titanate, wherein the strontium titanate is Y- and Ni-doped and has the general formula of (Sr a Y b ) d (Ti 1-c Ni c )O 3 , wherein a+b is greater than 1 and 0.8≦a≦1; 0<b≦0.2; 0<c≦0.1; and 1≦d≦1.2. 10. The method of claim 9 , wherein the fuel is a diesel fuel. 11. The method of claim 9 , wherein the fuel comprises less than about 30 mol % aromatic compounds. 12. The method of claim 9 , wherein the fuel comprises less than about 50 ppm sulfur-containing compounds.
