Features of the deactivation process of B-containing aluminum oxide during propane dehydrogenation
https://doi.org/10.18412/1816-0387-2026-3-58-65
Abstract
The deactivation of boron-containing γ-Al2O3 in the propane dehydrogenation reaction to olefinic hydrocarbons was studied. The main factors leading to a decrease in catalyst activity, selectivity, and stability were identified. The distribution and state of the active components in the catalytic system before and after the reaction were investigated. The nature and distribution of coke deposits formed on the catalyst during the reaction were determined. It was shown that boron-containing alumina exhibits high selectivity and operational stability in the conversion of propane to lower olefins.
