Continuous process for conversion of lignin to useful compounds
This specification discloses an operational continuous process to convert lignin as found in ligno-cellulosic biomass before or after converting at least some of the carbohydrates. The continuous process has been demonstrated to create a slurry comprised of lignin, raise the slurry comprised of lignin to ultra-high pressure, deoxygenate the lignin in a lignin conversion reactor over a catalyst which is not a fixed bed without producing char. The conversion products of the carbohydrates or lignin can be further processed into polyester intermediates for use in polyester preforms and bottles.

CHROMIUM-CATALYZED REACTIONS OF CARBON MONOXIDE WITH HYDROCARBONS IN THE PRESENCE OF UV LIGHT
A hydrocarbon compound and carbon monoxide are reacted in the presence of either a supported chromium (VI) catalyst or a supported chromium (II) catalyst, optionally with UV-visible light irradiation and/or exposure to an oxidizing atmosphere, followed by removing a reaction product containing an alcohol compound and/or a carbonyl compound from the respective chromium catalyst. Often, the reaction product contains one or more ketone and/or aldehyde compounds.
