Outline of Final Research Achievements

Nano-sized crystals of MFI, MOR, MTW and TON zeolites were successively synthesized. These crystals can be regarded as structured active sites with negligibly small resistance to mass transfer. Furthermore, these acidic properties were succeeded to be controlled by inserting Fe into their frameworks. MTW nano-sized crystal catalyst thus obtained showed high activity for methylation of 2-methyl-naphtalene. The deactivation of the catalyst could be remarkably prevented in liquid phase reaction under high pressures. MTW nano-sized crystal-layered catalyst membranes were successively prepared. The research on their application to the methylation is continuing, to confirm its validity.
