Abstract
ECNU-10, an analogue of MCM-49 with the 3-dimensional (3D) MWW topology, was synthesized using 1-adamantanamine as structure directing agent (SDA), which is the second example of 3D MWW zeolite obtained by direct hydrothermal synthesis. The synthesis condition was investigated and proton-type ECNU-10 showed similar Al distribution with conventional MCM-22 obtained by the interlayer condensation of a layer precursor, as revealed by 27Al 3Q MAS NMR analysis. The catalytic performance of ECNU-10 was evaluated in the alkylation and disproportionation reactions in comparison to another two MWW-type aluminosilicates of MCM-22 and SSZ-25.
