Embodiment 1
[0014] The performance evaluation of the catalyst was carried out on a fixed-bed reaction device at normal pressure. A stainless steel reactor with an inner diameter of 10 mm was used. The loading amount of the catalyst was 10 ml, the reaction temperature was 350 °C, and the liquid space velocity was 1 hour. -1 , reacted under normal pressure. Reaction product analysis adopts HP 6890 gas chromatography, hydrogen flame detector, HP-6 capillary column (60m * 0.25mm * 0.25μm), catalyst is Al-MCM-41, its SiO 2 / Al 2 o 3 The molar ratio was 50. The reaction results are shown in Table 1.
Embodiment 2~12
[0016] According to each step of [embodiment 1], just catalyzer adopts different catalyzer, and concrete test condition and reaction result are shown in Table 1.
