Process for producing 2-methyl-2-butene from a 5 carbon atom olefins cut containing 2-methyl-1-butene and at least one n-pentene

摘要

Process for producing 2-methyl-2-butene from a charge containing olefins of 5 carbon atoms, including 2-methyl-1-butene and at least one n-pentene, wherein a mixture of said charge with hydrogen and at least one sulfur compound is contacted with a supported catalyst comprising at least one noble metal from group VIII. The 2-methyl-1-butene of the charge is isomerized to 2-methyl-2-butene and the n-pentenes are hydrogenated.
