Abstract
Official abstract text for this publication.
Disclosed herein are a catalyst for hydrocracking reaction of high molecular weight components in bio-oil, a method for preparing the same and a method for bio-oil upgrading using the same. The catalyst includes a zeolite carrier; and at least one metal selected from the group consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) supported on the carrier. The catalyst promotes the hydrocracking of high molecular weight compounds contained in the bio-oil, but also inhibits the polymerization reaction of the decomposed product, thereby more effectively enhancing the hydrocracking reaction of the bio-oil.
First claim
Opening claim text (preview).
What is claimed is: 1. A hydrocracking catalyst for a bio-oil comprising: a zeolite carrier; and metals consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) are supported on the carrier, wherein the catalyst comprises nickel oxide and ruthenium oxide subsequently supported on the zeolite carrier on which cerium oxide is first supported, and wherein the hydrocracking catalyst is for a non-aqueous fraction of a bio-oil. 2. The hydrocracking catalyst according to claim 1 , wherein the zeolite carrier is at least one selected from the group consisting of HY, HZSM-5 and Hβ. 3. The hydrocracking catalyst according to claim 2 , wherein the zeolite carrier is HZSM-5. 4. The hydrocracking catalyst according to claim 1 , wherein the the combined amount of metals are supported in an amount of 1 to 30% by weight based on a total weight of the catalyst.
