Title:
OLEFIN ISOMERIZATION CATALYST AND PRODUCTION METHOD THEREFOR, AND 2-BUTENE PRODUCTION METHOD AND PROPYLENE PRODUCTION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/116548
Kind Code:
A1
Abstract:
The present invention provides an inexpensive olefin isomerization catalyst that has a high conversion rate and has high durability when isomerization reaction and regeneration are repeated. This olefin isomerization catalyst supports at least one alkali metal on a carrier that is obtained by using, as a raw material, magnesium oxide having a purity of not less than 56 wt% but less than 99 wt%.
