A reassembled HBeta zeolite (HBeta-Ct) was obtained via zeolitic dissolution-recrystallization successive treatment, and characterized by means of XRD, FT-IR, SEM, TEM, N-2 adsorption-desorption as well as NH3-TPD techniques. The characterization results manifested that the HBeta-Ct zeolite possessed more mesopores and less acid than the parent one. Catalyst activities of the parent and reassembled HBeta catalysts were investigated in detail in the vapor-phase Doebner-Von Miller reaction to quinolines. The results demonstrated that the reassembled HBeta zeolite showed enhanced catalyst stabili...
