Abstract
It was found that the conversion (by isomerisation or branching) of unsaturated fatty acids into branched fatty acids can be catalysed by materials having a microporous structure. Such a process gives high conversion rates and a high selectivity towards branched fatty acids, whilst a low amount of undesired by-products is obtained. Zeolites are preferred materials for catalysing said reaction.
Claims22
In a process for the isomerisation of fatty acids, in which a fatty acid feed comprising unsaturated fatty acids is contacted with a catalyst, the improvement wherein the catalyst comprises a material having a microporous structure.
In a process for the isomerisation of fatty acids, in which a fatty acid feed comprising unsaturated fatty acids is contacted with a catalyst, the improvement wherein the catalyst comprises a zeolite material having a microporous structure whereby said feed is converted into a mixture which is rich in branched fatty acids and low in oligomers.
