Abstract
The present invention relates to an isomerisation catalyst, in particular a zeolite catalyst. There is provided a method for making a particularly preferred zeolite catalyst by means of modifying catalytic zeolite materials. There is also provided a process for isomerising fatty acids or alkyl esters thereof to produce branched fatty acids employing such an isomerisation catalyst, a composition comprising branched fatty acids, and also use of the isomerisation catalyst.
Claims20
A method of producing branched fatty acids, comprising:
- contacting a starting material comprising unsaturated fatty acids with an isomerization catalyst;
- and
- isomerizing, with the catalyst, an amount of the unsaturated fatty acids to form a composition comprising branched fatty acids;
- wherein the catalyst is a zeolite comprising micropores and mesopores and wherein a micropore volume (Vmicro) of the catalyst is from 1% to 50% of a total pore volume (Vpore) of micropores and mesopores of the catalyst.
A method of producing branched fatty acids, comprising:
- contacting a starting material comprising unsaturated fatty acids with an isomerization catalyst;
- and
- isomerizing, with the catalyst, an amount of the unsaturated fatty acids to form a composition comprising branched fatty acids;
- wherein the catalyst is a zeolite comprising micropores and mesopores and wherein the catalyst has a surface area (Stotal) of 450 m2/g to 650 m2/g as measured via BET.
