Abstract:
Implementations of the disclosed subject matter provide methods for producing ethylene glycol from a carbohydrate feed may include contacting, in a first reactor under hydrogenation conditions, the carbohydrate feed with a bi-functional catalyst system. The bi-functional catalyst system may include a heterogeneous hydrogenation catalyst, and a soluble retro-Aldol catalyst. The carbohydrate feed may include a concentration of carbohydrate, in the total solution entering the first reactor, of 5-40 wt % in a solvent. An intermediate product stream may be obtained from the first reactor including ethylene glycol. The hydrogenation conditions may include a temperature in the range of from 180-250° C.

Claim (Index 1):
A method for producing ethylene glycol from a carbohydrate feed comprising:\n a) contacting, in a first reactor under hydrogenation conditions, the carbohydrate feed with a bi-functional catalyst system comprising:\n 1) a heterogeneous hydrogenation catalyst, and \n 2) a soluble retro-Aldol catalyst; and,\n wherein the carbohydrate feed comprises a concentration of carbohydrate, in the total solution entering the first reactor, of 5-40 wt % in a solvent; \n \n b) obtaining an intermediate product stream, from the first reactor, comprising ethylene glycol; and wherein the hydrogenation conditions comprise a temperature in the range of from 180-250\u00b0 C.
