An olefin isomerization process employs a basic metal oxide catalyst, such as magnesium oxide, which retains at least about 85 percent of its initial activity for at least about 168 hours of on-stream time. The catalyst is preferably a high purity magnesium oxide. The olefin isomerization process and...http://www.google.es/patents/US6875901?utm_source=gb-gplus-sharePatente US6875901 - Olefin isomerization process
