Embodiment 1
[0028] A preparation method and a hydrogenation upgrading method of a catalyst for improving gasoline hydrogenation upgrading performance:
[0029] A. Add 0.35g sodium hydroxide, 1.04g sodium aluminate, 1.0g 18-crown-6, 0.034g sodium phosphate, 4.74g deionized water and 6.3g silica sol into the reaction kettle and stir at 25 degrees Celsius dissolved as solution I;
[0030] B. Add 0.12g 3-mercaptopropyltrimethoxysilane, 0.15g sodium hydroxide and 2g deionized water into the beaker and stir to dissolve, as solution II;
[0031] C. Add solution II dropwise to solution I and stir for 3 hours, then age at 25 degrees Celsius for 24 hours, then transfer to a reaction kettle and crystallize at 100 degrees Celsius for 96 hours to obtain a PtRu / EMT-FAYU zeolite microcrystalline emulsion;
[0032] D, the P123 organic matter of 2g is joined in the hydrochloric acid solution to dissolve and disperse, drop the tetraethyl orthosilicate of 4.28g and the EMT-FAU zeolite microcrystalline emul...
