Embodiment 1
[0032] Weigh 23.0g tetraethyl orthosilicate, 1.0g butyl titanate, and 20.3g lauryl polyoxyethylene ether; stir and dissolve 24.5g lauryl polyoxyethylene ether in 100ml absolute ethanol, heat Stir for 1 h; slowly add 23.0 g of ethyl orthosilicate dropwise to the three-neck flask under stirring; half an hour later slowly add 4.0 g of butyl titanate dropwise, and finally do not add absolute ethanol to 220 ml. The pH of the reaction system was measured to be 2.0 with a magnetic pH meter, and the temperature was controlled to stir at 75° C. for 24 hours. After cooling and standing for 3 hours, the crystalline product was separated; after drying at 110°C, it was calcined in a muffle furnace at 550°C for 6 hours to obtain the original titanium-silicon molecular sieve catalyst powder.
[0033] The raw titanium-silicon molecular sieve powder obtained above was pressed into tablets and sieved, and the 20-40 mesh particles were packed into a fixed-bed reactor in a catalyst evaluation dev...
