Embodiment 1
[0027] Add 1 g of TS-1 for industrial use, 1 g of CNF and 50 ml of distilled water into a 150 ml three-necked flask, and stir at 500 rpm for 24 hours to obtain a mixture.
[0028] Filter the mixture and dry it at 120°C for 12 hours to obtain the mixed TS-1 / CNF composite catalyst of the present invention, which is ready for use.
[0029] Wherein: the weight percent of the titanium silicon molecular sieve TS-1 is 50.0%, and the carbon nanofiber is 50.0%. The particle size of the titanium-silicon molecular sieve is less than or equal to 150nm, and the particle size range of the composite catalyst is 5-50 μm. Scanning electron microscope photos as figure 1 shown.
