  • Al.sub.2 O.sub.3 alkene isomerization process and catalyst
    Patent number: 5043523
    Abstract: Gamma alumina having a sodium content of less than 0.01 weight percent sodium calculated as Na.sub.2 O and said alumina modified with silicon were found to be superior catalysts for the isomerization of alkenes having at least four carbon atoms, preferably with 0.01 to 1 mole of water per mole of alkene present during the isomerization. Both skeletal isomerization (e.g. n-butene to isobutene) and position isomerization (e.g. butene-2 to butene-1) are obtained.

  • Oxidative dehydrogenation of amylenes
    Patent number: 4973793
    Abstract: Cofeeding butylenes with amylenes in a catalytic oxidative dehydrogenation reaction substantially improves the conversion of the amylenes. The approved amylene conversion is obtained by the oxidative dehydrogenation of mixtures of amylenes and from 10 to 95 mole % butylenes.
