FIELD: petrochemical processes.
SUBSTANCE: branched olefins from isomerization feedstock in the form of linear olefin/paraffin mixture containing 5 to 50% of linear olefins having 7 to 28 carbon atoms are obtained in the first isomerization stage, wherein carbon backbone of linear olefins in the isomerization feedstock is isomerized when in contact with isomerization catalyst, which is effective to isomerize carbon backbone in linear olefin blend to convert the latter into olefin blend, wherein average number of branches in molecule chain is at least 0.7, followed by second stage, wherein branched and linear molecules are separated, the former being essentially olefinic molecules and the latter olefinic and/or paraffin molecules. Resulting branched olefins are served as starting material for production of alcohols and alkylbenzenes.
EFFECT: enabled olefin branching control.
