摘要：
Hierarchical zeolitic catalysts with varying ratios of micro- and mesoporosity were prepared by recrystallization of ferrierite (FER) in alkaline solution in the presence of cetyltrimethylammonium bromide. The catalysts were characterized by XRD, TPD-NH3, Fr-IR, nitrogen adsorption-desorption, SEM, TEM. The influence of alkali concentration on the distribution of micro- and mesopores is discussed. The recrystallization process led to a significant increase of accessibility of the acid sites, together with a decrease of the total acidity. The catalytic properties were investigated in 1-butene isomerization. All recrystallized materials showed improved catalytic activity and selectivity in isomerization. (C) 2011 Elsevier Inc.
