Example Embodiment
[0020] [Example 1]
[0021] Add 10 g of hexadecylamine, 5 g of dodecylamine to 80 ml of H at room temperature with stirring 2 O, 60 mL of ethanol and 5 mL of (1M) hydrochloric acid, and stirred until the solution was one-phase. 65.0 g of ethyl orthosilicate dissolved in 30 ml of ethanol was added to the above mixed solution, stirred for 30 minutes, and then crystallized for 24 hours. The resulting solid was filtered and washed with water to remove residual Cl - . The washed solid was dried at 110°C for 12 hours, and then calcined at 600°C for 4 hours to obtain HMS with hexagonal mesoporous structure.
[0022] After crushing and sieving the powdery sample prepared above (forming pressure is 20MPa), take 10.0 grams of 20-40 mesh particles and put them in a quartz tubular reactor, and dry them at 120°C for 2 hours under a nitrogen atmosphere. Raise the temperature to 300 °C and replace 1.2 g of TiCl with nitrogen 4Saturated steam was brought in, followed by raising the tempe...

[0023] [Example 2]
[0024] Except for TiCl 4 The remaining conditions are the same as [Example 1] except that the amount of 1.5 grams. The specific surface area of the prepared Ti-HMS catalyst is 800 m 2 / g, the hole volume is 0.85 cm 3 / g, the average pore size is
