γ-Al2O3载体的形貌调控及其对丙烷脱氢催化剂的影响综述
A Review of the Morphological Regulation of γ-Al2O3 Spport and Its Effect on Propane Dehydrogenation Catalysts
摘要
Abstract
γ-Al2O3 is commonly used as a carrier for catalysts,and the physicochemical properties of its surface greatly influence the catalytic reaction.The exposed Al coordination environment can be regulated by adjusting the morphology of γ-Al2O3 carriers by changing the synthesis method and synthesis conditions.The energy of the exposed crystal lattice of carriers with different morphologies is different,which will directly affect the acidity of the carrier and the interaction between active metals,and active metals and carriers,thus creating different loading sites of active metals.Carrier morphology control is an effective way to regulate the structure of the active components.The regulation of the support morphology of the propane dehydrogenation catalyst will affect the catalytic performance.The research progress of γ-Al2O3 support was reviewed from the aspects of preparation method,morphology control,and its influence on propane dehydrogenation catalyst.关键词
