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 producing ketones includes a) providing a feedstock of biological origin having fatty acids and/or fatty acid derivatives having an average chain length of 24 C-atoms or less; b) subjecting the feedstock to a catalytic ketonization reaction in the presence of aK2O/TiO2-catalyst; and c) obtaining from the ketonization reaction a product stream having ketones, which ketones have a longer average hydrocarbon chain length than the average hydrocarbon chain length in the feedstock, wherein step b) is carried out directly on the feedstock and in the presence of the K2O/TiO2-catalyst as the sole catalyst applied in the ketonization reaction.

Abstract: A method for producing a renewable base oil from a feedstock of biological origin includes providing a feedstock, the feedstock including: 2-95 wt % of a mixture of free fatty acids; 5-98 wt % fatty acid glycerols selected from mono-glycerides, di-glycerides and tri-glycerides of fatty acids; 0-50 wt % of one or more compounds selected from the list consisting of: fatty acid esters of the non-glycerol type, fatty amides and fatty alcohols; a major part of the feedstock being a mixture of free fatty acids and fatty acid glycerols; subjecting all or part of the feedstock to ketonisation reaction conditions where two free fatty acids react to yield a ketone stream, and subjecting the ketone stream to both hydrodeoxygenation and to hydroisomerisation reaction conditions, to yield a deoxygenated and isomerised base oil product stream containing the renewable base oil.

Abstract: A number of different branched hydrocarbon compounds (formula I) having a star-like configuration (S) are prepared from renewable oils containing fatty acids or derivatives containing fatty acids. The branched hydrocarbon compounds may be isolated individually or in mixtures, and may be used as part of base oils, such as renewable base oils (RBOs). A process for preparing the branched hydrocarbon compounds of formula I involve conditions that favour a trimerisation reaction followed by hydrotreating conditions. The compounds of formula I may be made by catalytically treating renewable material in a process, and the compounds have desirable qualities relating to lubrication, cold flow as well as having a low Noack volatility.
