A process is presented for the production of high value chemicals from lignin. The process comprises combining several internal steps to use the hydrogen generated by the process, rather than adding an external source of hydrogen. The process can combine the decomposition of oxygenates formed during
A process is presented for the production of high value chemicals from lignin. The process comprises combining several internal steps to use the hydrogen generated by the process, rather than adding an external source of hydrogen. The process can combine the decomposition of oxygenates formed during the deoxygenation process with hydrogenation of deoxygenated lignin compounds.

1. A process for the production of hydrocarbons and hydrogen from lignin, comprising: combining lignin with water and an acidic or basic catalyst to form an intermediate stream comprising lignin-D and light oxygenates;decomposing the light oxygenates with a decomposition catalyst to form a second intermediate stream comprising hydrogen, wherein the decomposition catalyst comprises a mixture of metals on a support; andcombining the second intermediate stream with a hydrogenation catalyst to form a third stream comprising hydrogenated or partially hydrogenated compounds. 2. The process of claim 1 further comprising contacting the third stream with a dehydrogenation catalyst to form a stream comprising aromatic compounds. 3. The process of claim 1 wherein the light oxygenates comprises alcohols having from 1 to 3 carbons. 4. The process of claim 3 wherein the light oxygenates comprise methanol. 5. The process of claim 1 wherein the decomposition step is performed by decomposing the light oxygenates in the intermediate stream with steam. 6. The process of claim 1 wherein the decomposition step is performed by contacting the light oxygenates in the intermediate stream with a decomposition catalyst. 7. The process of claim 4 wherein the decomposition step is performed by decomposing methanol to form carbon dioxide and hydrogen. 8. The process of claim 1 further comprising separating the hydrogen stream into a hydrogen rich stream and a second stream. 9. The process of claim 1 wherein the support is selected from the group consisting of inorganic oxides, zeolites, molecular sieves, carbon, silica, silica-alumina, boron nitride, silica nitride, and mixtures thereof. 10. The process of claim 1 wherein the metals are selected from the metal selected from chromium, gold, zinc, copper, platinum, silver, palladium, rhodium, rhenium, osmium, ruthenium, iridium and mixtures thereof. 11. The process of claim 1 wherein the hydrogenation catalyst comprises a noble metal on a support. 12. The process of claim 11 wherein the noble metal is selected from the group consisting of platinum (Pt), palladium (Pd), and mixtures thereof. 13. The process of claim 11 wherein the catalyst support is selected from the group consisting of zeolites, molecular sieves, Al2O3, SiO2, MgO, ZrO2, TiO2, mixed metal oxides, carbon, and mixtures thereof. 14. A process for the production of hydrocarbons and hydrogen from lignin, comprising: combining lignin with water and an acidic or basic catalyst to form an intermediate stream comprising lignin-D and light oxygenates; andcontacting the intermediate stream with a decomposition catalyst and a hydrogenation catalyst to form a third stream comprising hydrogenated compounds,wherein the decomposition catalyst comprises at least one metal on a support. 15. The process of claim 14 further comprising contacting the third stream with a dehydrogenation catalyst to form a stream comprising aromatic compounds 16. The process of claim 14 wherein the decomposition catalyst and hydrogenation catalyst are admixed in a single vessel. 17. The process of claim 14 wherein the decomposition catalyst and hydrogenation catalyst are intermingled on the same catalyst particles. 18. The process of claim 14 wherein the oxygenates comprise methanol. 19. The process of claim 14 wherein the hydrogen produced by the decomposition of the light oxygenates is consumed in the hydrogenation of organic compounds in the intermediate stream.
