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.

本研究的主要目的是实现沸石晶体的尺寸可控合成和发展纳米沸石催化剂的设计方法。合成了各种类型的沸石(MFI、TON、MOR、BEA、FAU和MTW)，并成功地控制了它们的晶粒度。特别是在MFI、MOR、MTW、TON沸石中，得到了粒径小于100 nm的纳米沸石和粒径大于1000 nm的大晶沸石。结果表明，TON沸石的丙烯醛收率高达80%以上，MFI和MTW沸石可选择性地合成2，6-DMN。此外，沸石的晶粒度影响产物的选择性和催化剂的稳定性，将纳米沸石用作催化剂可以显著提高产物的选择性和催化剂的稳定性。
