WebMethods of converting isobutylene to C5+ compounds. The methods may include contacting isobutylene with a skeletal isomerization catalyst to provide a mixture of C4 olefins, and then contacting the mixture of C4 olefins with a metathesis catalyst to convert the mixture of C4 olefins to a product mixture. The product mixture may include C5+ olefins. WebThe ethylene oligomerization catalyst composition containing the halogen-containing compound can be used to catalyze ethylene oligomerization, trimerization and tetramerization reactions. As a ligand of a catalyst for ethylene oligomerization, a fluoropolymer can effectively improve the catalytic performance of a catalyst system, and ...
