Isomerization of unsaturated hydrocarbons by a molecular sieve treatment

Abstract

Molecular sieve treatment for separation of sterane and triterpane compounds from n-alkanes leads to isomarization of oleanenes in the bitumen extracted from the Shiiya Formation, where 24-norolean-12-ene and olean-12-ene decrease with increasing of Δ¹³⁽¹⁸⁾, Δ¹⁸isomers at room temerature.
