Abstract
Official abstract text for this publication.
Disclosed herein are a calcium salts-supported metal catalyst, a method for preparing the same, and a method for the hydrodeoxygenation reaction of oxygenates using the same. The catalyst, in which a metal catalyst is supported on a carrier of a calcium salt, for example, calcium carbonate, has the effect of increasing the efficiency of hydrodeoxygenation reaction of oxygenates.
First claim
Opening claim text (preview).
What is claimed is: 1. A catalyst for hydrodeoxygenation reaction comprising at least one carrier selected from the group consisting of calcium chloride, calcium fluoride, calcium hydroxide, calcium nitrate, calcium acetate, calcium citrate, calcium lactate, calcium phosphate, calcium gluconate, calcium sulfate, and calcium iodate, and a metal supported on the carrier, wherein the metal comprises at least one of nickel (Ni), cobalt (Co), copper (Cu), platinum (Pt), rhodium (Rh), or ruthenium (Ru), wherein the content of the metal is 3% to 15% by weight based on the total weight of the catalyst, and the catalyst removes oxygen atoms from an oxygenate to provide a deoxygenated compound. 2. The catalyst for hydrodeoxygenation reaction according to claim 1 , wherein the oxygenate is an oxygen-containing hydrocarbon compounds having 5 to 20 carbon atoms. 3. The catalyst for hydrodeoxygenation reaction according to claim 1 , wherein the oxygenate comprises at least one of phenol, alcohol, aldehyde, ketone, ether, or ester. 4. The catalyst for hydrodeoxygenation reaction according to claim 1 , wherein the metal comprises ruthenium (Ru). 5. A method for preparing the catalyst for hydrodeoxygenation reaction according to claim 1 , comprising the steps of: (1) mixing a solution of a metal precursor with a carrier comprising a calcium salt to impregnate the carrier with the solution; and (2) firing the carrier impregnated with the solution. 6. The method for preparing the catalyst for hydrodeoxygenation reaction according to claim 5 , wherein the firing of the impregnated carrier is carried out in an air atmosphere at 100 to 500° C. 7. A catalyst for hydrodeoxygenation reaction comprising ruthenium (Ru) supported on a carrier selected from the group consisting of calcium chloride, calcium fluoride, calcium hydroxide, calcium nitrate, calcium acetate, calcium citrate, calcium lactate, calcium phosphate, calcium gluconate, calcium sulfate, and calcium iodate, wherein the catalyst removes oxygen atoms from an oxygenate to provide a deoxygenated compound, wherein the oxygenate is a degradation product produced by thermal, chemical or biological degradation of biomass including wood, herbs, or algae, or a degradation product produced from an organic polymer. 8. The catalyst for hydrodeoxygenation reaction according to claim 7 , wherein the catalyst does not exhibit a significant change in hydrodeoxygenation reaction activity following two regeneration wash and dry cycles.
