Abstract
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.
Claims20
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 to form a second intermediate stream comprising hydrogen;
- and
- combining the second intermediate stream with a hydrogenation catalyst to form a third stream comprising hydrogenated or partially hydrogenated compounds.
