Title:
中性アミンを使用する中気孔寸法ゼオライトの製造法及び中気孔寸法ゼオライト組成物
Document Type and Number:
Japanese Patent JP4623762
Kind Code:
B2
Abstract:
There is disclosed a process for preparing the zeolite ZSM-5, which comprises:
(a) preparing an aqueous solution from (1) sources of an alkali metal oxide, alkaline earth metal oxide or mixtures thereof; (2) sources of an oxide selected from the oxides of aluminum, iron, gallium, indium, titanium, or mixtures thereof; (3) sources of an oxide selected from oxides of silicon, germanium or mixtures thereof; and (4) cyclopentylamine;
(b) maintaining the aqueous solution under conditions sufficient to form crystals of the zeolite; and
(c) recovering the crystals of the zeolite. The general formula of the zeolite ZSM-5, as-synthesized and in the anhydrous state, in terms of mole ratios, is as follows:
YO 2 /W 2 O 3 ¥ 15
Q/YO 2 0.02-0.10
M 2 / n /YO 2 0.015-0.10
wherein Y is silicon, germanium or a mixture thereof; W is aluminum, gallium, indium, iron, titanium, or mixtures thereof; Q is cyclopentylamine; M is alkali metal cation, alkaline earth metal cations or mixtures thereof, and n is the valence of M.
