Abstract: A process for the skeletal isomerization of olefins wherein the olefins are contacted with a SKISO-11 alumina base catalyst to convert into isomerized products effectively under the conversion conditions comprising a temperature of above 200.degree. C. to about 650.degree. C., the pressure of 0.3 to about 10 atmospheres and a molar ratio of hydrogen or nitrogen to olefins feed from 0 to about 10.
