Abstract: Catalytic conversion of ketoacids is disclosed, including methods for increasing the molecular weight of ketoacids. An exemlary method includes providing in a reactor a feedstock having at least one ketoacid. The feedstock is then subjected to one or more C—C-coupling reaction(s) in the presence of a catalyst system having a first metal oxide and a second metal oxide.

Abstract: 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.

Abstract: A method for conversion of levulinic acid and to a hydrocarbon composition obtainable by the method. The method includes a step of providing a feedstock, a conversion step of subjecting the feedstock to a C—C coupling reaction and a hydrotreatment, and a hydrodeoxygenation step. The content of levulinic acid dimer derivatives having 4 oxygen atoms subjected to the hydrodeoxygenation step is 20 wt.-% or more.
