The present disclosure relates to a method for upgrading lignocellulosic material carbohydrates and/or carbohydrate derivatives by dimerisation and/or oligomerisation using specific catalysts and to the use of the upgraded products.

Upgrading lignocellulosic or carbohydrate material

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&#x2014;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.

Renewable hydrocarbons, method for producing the same and use thereof

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&#x2014;C-coupling reaction(s) in the presence of a catalyst system having a first metal oxide and a second metal oxide.

Method for catalytic conversion of ketoacids and hydrotreament to hydrocarbons

Provided are fuel components, a method for producing fuel components, use of the fuel components and fuel containing the fuel components based on 5-nonanone.

Upgrading 5-nonanone

Methods and uses of a good lubricity fraction obtainable from thermal treatment of levulinic acid and subsequent hydrogenation and fractionation are disclosed.

Renewable diesel fuel composition

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&#x2014;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&#x2014;C-coupling reaction(s) at a temperature of at least 200&#xb0; C.
