Abstract

Methods are provided for producing an alcohol-containing pyrolysis product. Initially, a hydrocarbon feedstock is pyrolyzed in the presence of a catalyst system, the catalyst system comprising a basic metal oxide catalyst and a hydrogenation metal catalyst. A pyrolysis product is produced that contains at least one alcohol. The basic metal oxide catalyst is comprised of at least one metal from Group 2, Group 3 including Lanthanides and Actinides, or Group 4 of the Periodic Table of Elements, and the supported hydrogenation metal catalyst is comprised of at least one metal from Group 6 or Groups 8-10 of the Periodic Table of Elements.

First claim

What is claimed is:

1. A method of producing an alcohol-containing pyrolysis product, the method comprising:
pyrolyzing a hydrocarbon feedstock in the presence of a solid heat absorbing material comprising a basic metal oxide catalyst and a supported hydrogenation metal catalyst to produce a pyrolysis product that contains at least one alcohol, wherein the basic metal oxide catalyst comprises at least one metal selected from the group consisting of Group 2, Group 3 including Lanthanides and Actinides, and Group 4 of the Periodic Table of Elements, and wherein the supported hydrogenation metal catalyst comprises at least one metal selected from the group consisting of platinum and palladium;
wherein the basic metal oxide catalyst and supported hydrogenation metal catalyst comprise about 1-20 wt % of the solid heat absorbing material.

2. The method of claim 1 , wherein a hydrogenation metal of the hydrogenation metal catalyst is supported on the basic metal oxide catalyst.

3. The method of claim 1 , wherein the hydrogenation metal catalyst is supported on a refractory oxide support.

4. The method of claim 1 , wherein the hydrocarbon feedstock comprises biomass material.

5. The method of claim 1 , wherein the basic metal oxide catalyst is a Group 2 metal oxide.

6. The method of claim 1 , wherein the Group 3 metal comprises at least one of yttrium, cerium, and praseodymium.

7. The method of claim 1 , wherein the Group 2 metal comprises at least one of magnesium or calcium.
