Synthesis of ZSM-5/Porous Mullite Honeycomb Composite from Sintered Malaysia Kaolin via Hydrothermal Processing

2001 Journal of the Ceramic Society of Japan  
The synthesis and properties of ZSM-5 film on a porous mullite honeycomb have been investigated using Malaysia kaolin. Amorphous silica-glass in the kaolin honeycomb sintered at 1450•Ž was used as a source for ZSM-5 formation. The honeycomb was hydrothermally treated in NaOH, tetrapropylammonium bromide, and water to prepare a novel ZSM-5/mullite honeycomb composite via in-situ crystallization at 160 to 180•Ž. This paper describes the formation of mullite from Malaysia kaolin at 1400 to 1500•Ž,
