METHOD FOR CATALYTIC CONVERSION OF KETOACIDS VIA KETOACID DIMER INTERMEDIATE AND HYDROTREATMENT TO HYDROCARBONS

摘要

The present invention relates to catalytic conversion of ketoacids, including methods for increasing the molecular weight of ketoacids. The method can include providing in a reactor a raw material having at least one ketoacid. The raw material is then subjected to one or more C-C-coupling reaction(s) in the presence of an ion exchange resin catalyst to produce at least one ketocid dimer. The method can include providing in a reactor a feedstock having the at least one ketoacid dimer and subjecting the feedstock to one or more C-C-coupling reaction(s) at a temperature of at least 200° C.

1. A method for increasing the molecular weight of a ketoacid, the method comprising:
providing in a reactor a raw material comprising having at least one ketoacid; subjecting the raw material to first C-C-coupling reaction(s) in a presence of an ion exchange resin catalyst so as to produce at least one ketoacid dimer; providing in a reactor a feedstock having the at least one ketoacid dimer; and subjecting the feedstock to second C-C-coupling reaction(s) at a temperature of at least 200° C.
