Selective and stable iso-butene production over highly dispersed VO(x) species on SiO(2) supports via combining oxidative and non-oxidative iso-butane dehydrogenation.
For the first time, we demonstrated that combining oxidative and non-oxidative dehydrogenation of iso-butane in one reactor system is an attractive approach for iso-butene and hydrogen production. Iso-butene yields above 40% at iso-butene selectivity above 80% and CO(x) selectivity below 2% were achieved over SiO(2)-supported highly-dispersed VO(x) species during at least 20 h on-stream at 833 K.
