Influence of sodium on the physico-chemical and catalytic properties of magnesium oxide

摘要: Physico-chemical and catalytic properties of two series catalysts comprising magnesia sodium were determined. The first (I) was prepared by doping with varying amounts NaOH. second (II) obtained evaporating metallic onto MgO preparations precalcined at different temperatures.The concentration strengths basic acid sites, as well the one-electron donor acceptor measured, specific surface areas Catalytic activity in isomerization pent-1-ene, trans-pent-2-ene conversion cumene studied. It concluded that displayed remarkably strong properties. Also, it proved sites coexist on surfaces sites. alkene dehydrogenation unambiguously associated presence well-defined active
