Embodiment 1

[0310] Example 1 illustrates the production of FAPO-2 by using morpholine and triethylamine as templates.

[0311] To a mixture of 28.05 g of water and 11.53 g of 85% phosphoric acid, 6.8 g of pseudo-boehmite (containing 25% water, produced by Condea) was gradually added and stirred. This is Liquid A. In addition to liquid A, 2.78 g of ferrous sulfate heptahydrate, 5.05 g of morpholine, 4.35 g of triethylamine and 29 g of water were mixed to prepare a liquid. It was gradually added to Liquid A and stirred for further 3 hours to prepare a starting reaction mass having the following composition.

[0312] 0.2FeSO 4 :Al 2 o 3 :P 2 o 5 : 1.16 morpholine: 0.86 triethylamine: 70H 2 o

[0313] This starting reaction material was fed into a 200-cc stainless steel autoclave having a Teflon (registered trade name) inner cylinder, and reacted at 160° C. for 4 days while remaining still. After thus reacting, it was cooled, its supernatant liquid was removed by decantation, and the...

Embodiment 2

[0347] Zeolite was produced under the same conditions as in Example 1, however, the synthesized template-containing zeolite was calcined in nitrogen. Table 7 shows the XRD data of the zeolites thus obtained.

[0351] Figure 9 is the water vapor-air isotherm of the zeolite measured at 55°C by using an adsorption isothermal calorimeter (Bellsorb 18, Nippon Bell). Specifically, the samples were analyzed under the following conditions: the adsorption temperature in the thermostat was 60°C; the adsorption temperature was 55°C; the initial pressure was 3.0 Torr, the pressure setting was 0; the saturated vapor pressure was 118.11 mmHg, and the equilibration time is 500 seconds.

Embodiment 3

[0353] The sample calcined in Example 2 was recalcined under the same conditions as in Example 1 in air. Table 7 shows the XRD data of the zeolites thus obtained. It can be seen that the recalcined zeolite is almost the same as the zeolite in Example 1.
