Isolated Boron in Zeolite for Oxidative Dehydrogenation of Propane
SCIENCE(2021)
摘要
Isolating and stabilizing boron Oxidative dehydrogenation of propane can produce propene from shale gas and help to replace petroleum as a propene feedstock. Boron-based catalysts can have high selectivity to propene, but the water by-product can deactivate the catalyst by hydrolyzing boron. Zhou et al. synthesized boron-doped silicate zeolites containing isolated boron sites that were stable against hydrolysis. The catalyst could achieve one-pass propane conversions up to ∼44% with selectivities for propene and >80% for ethene. They observed no deactivation after a 210-hour continuous test.
