| Research Abstract |
Main objective of this research is a size-controlled synthesis for zeolite crystal and a development of design method for nano-zeolite catalyst. Various types of zeolites (MFI, TON, MOR, BEA, FAU and MTW) were synthesized and their crystal sizes could be successfully controlled. Especially, in MFI-，MOR-，MTW-，TON-type zeolites, the nano-crystalline zeolites with the size below 100 nm and macro-crystalline zeolite with the size above 1000 nm were obtained.Acrolein production from glycerol and 2,6-dimethyl naphthalene (2,6-DMN) production from 2-methyl naphthalene were conducted using zeolite catalysts. It is found that TON zeolite exhibits a high yield of acrolein above 80 % and that 2,6-DMN is selectively produced using MFI and MTW zeolites. Moreover, the crystal sizes of zeolite affect the product selectivity as well as the catalyst stability, the values of which are drastically improved by applying the nano-crystalline zeolite as a catalyst.
