Conversion of ethanol to C
Methods, systems and catalysts for converting an alcohol containing feedstock to an upgraded material in a single catalyst bed wherein a feedstock is fed to a catalyst under preselected conditions to obtain an intermediate; and condensing the intermediate through an aldol condensation reaction to yield a product containing an upgraded material. In one instance the feedstock includes ethanol, the catalyst is a mixed metal oxide catalyst and the upgraded material is typically a C 5 + ketone(s) or alcohol(s), such as 2-pentanone, 2-heptanone, 4-heptanone and 2-nonanone.
1. A method for converting an ethanol containing feedstock to an upgraded material in a single catalyst bed the method comprising the steps of:
introducing the feedstock to a mixed metal oxide catalyst comprising ZrO2-ZnO with 0.05 wt % Pd as promoter under preselected conditions to obtain an intermediate; and condensing the intermediate through an aldol condensation reaction to yield a product containing an upgraded material.
2. The method of claim 1 wherein the upgraded material is a C 5 + ketone(s) or alcohol(s).
3. The method of claim 1 wherein the preselected conditions include a temperature between 300-400° C. and a pressure of atmospheric-500 psig.
4. The method of claim 2 wherein the upgraded material is selected from the group consisting of 2-pentanone, 2-heptanone, 4-heptanone and 2-nonanone.
5. A method for converting an ethanol containing feedstock to an upgraded material in a single catalyst bed the method comprising the steps of:
introducing the feedstock to a ZrO2-ZnO with 0.05 wt % Pd promoter catalyst under a preselected conditions to obtain an intermediate; and condensing the intermediate through an aldol condensation reaction to yield a product containing a C 5 + ketone(s) or alcohol(s).
6. The method of claim 5 wherein the preselected conditions include a temperature between 300-400° C. and a pressure of atmospheric-500 psig.
7. The method of claim 5 wherein the C 5 + ketone(s) or alcohol(s) is selected from the group consisting of 2-pentanone, 2-heptanone, 4-heptanone and 2-nonanone.
8. A method for converting an ethanol alcohol containing feedstock to an upgraded material in a single catalyst bed the method comprising the steps of:
introducing the feedstock to a CuO—MgO—Al2O3 catalyst under preselected conditions to obtain an intermediate; and condensing the intermediate through an aldol condensation reaction to yield a product containing an upgraded material.
9. The method of claim 8 wherein the upgraded material is a C5+ ketone(s) or alcohol(s).
10. The method of claim 8 wherein the preselected conditions include a temperature between 300-400° C. and a pressure of atmospheric-500 psig.
11. The method of claim 9 wherein the upgraded material is selected from the group consisting of 2-pentanone, 2-heptanone, 4-heptanone and 2-nonanone.
12. A method for converting an ethanol containing feedstock to an upgraded material in a single catalyst bed the method comprising the steps of:
introducing the feedstock to a CuO—MgO—Al 2 O 3 catalyst under a preselected conditions to obtain an intermediate; and condensing the intermediate through an aldol condensation reaction to yield a product containing a C5+ ketone(s) or alcohol(s).
13. The method of claim 12 wherein the preselected conditions include a temperature between 300-400° C. and a pressure of atmospheric-500 psig.
14. The method of claim 12 wherein the C5+ ketone(s) or alcohol(s) is selected from the group consisting of 2-pentanone, 2-heptanone, 4-heptanone and 2-nonanone.
