[0093]
[0094] ZSM-22 zeolite composed of a crystalline aluminosilicate having a Si / Al ratio of 45 (hereinafter also referred to as "ZSM-22") was produced by hydrothermal synthesis in the following procedure.
[0095] First, the following four aqueous solutions were prepared.
[0096] Solution A: a solution obtained by dissolving 1.94 g of potassium hydroxide in 6.75 mL of ion-exchanged water.
[0097] Solution B: a solution in which 1.33 g of aluminum sulfate 18 hydrate was dissolved in 5 mL of ion-exchanged water.
[0098] Solution C: A solution obtained by diluting 4.18 g of 1,6-hexanediamine (organic template) with 32.5 mL of ion-exchanged water.
[0099] Solution D: a solution obtained by diluting 18 g of colloidal silica (Ludox AS-40 manufactured by Grace Davison) with 31 mL of ion-exchanged water.
[0100] Next, solution A was added to solution B, and stirred until the aluminum component was completely dissolved. After solution C was added to this mixed solution, ...

[0112] A ZSM-48 type zeolite having an organic template and having a Si / Al ratio of 45 (hereinafter also referred to as "ZSM-48") was synthesized based on Applied Catalysis A: General vol. 299 (2006) 167-174.
[0113] First, prepare the following four reagents.
[0114] Reagent E: 2.97 g of sodium hydroxide.
[0115] Reagent F: 0.80 g of aluminum sulfate 18 hydrate.
[0116] Reagent G: 26.2 g of 1,6-hexanediamine (organic template).
[0117] Reagent H: 0.9ml of 98% sulfuric acid solution
[0118] Reagent 1: 75 g of colloidal silicon dioxide (Ludox AS-40 manufactured by Grace Davison Company) aqueous solution (SiO 2 Concentration is 40%).
[0119] Next, the above-mentioned reagents E, F, G, H, and I were added to 180 mg of ion-exchanged water, and stirred at room temperature for 2 hours to completely dissolve them.
[0120] The gel-like substance obtained by the above operations was transferred to a stainless steel autoclave reactor with an internal volume of 10...

[0125]
[0126] Based on the method described in JP2006-523136 A, SSZ-32 zeolite (hereinafter also referred to as "SSZ-32") was produced by hydrothermal synthesis in the following procedure.
[0127] Sodium hydroxide, aluminum sulfate, colloidal silicon dioxide, isobutylamine, and N-methyl-N'-isopropyl-imidazolium cations were mixed according to the following molar ratios.
[0128] SiO 2 / Al 2 o 3 =35,
[0129] The total amount of isobutylamine and N-methyl-N'-isopropyl-imidazolium cations is SiO 2 0.2 times of
[0130] The gel-like substance obtained by the above operations was transferred to a stainless steel autoclave reactor with an internal volume of 100 mL, and the autoclave reactor was rotated on a tumbling device at a speed of about 60 rpm in a furnace at 160° C. for 60 hours to perform hydrothermal treatment. synthesis reaction. After the reaction was completed, the reactor was cooled and opened, and dried overnight in a dryer at 60° C. to obtain SSZ-32 with a...
