| description | The invention relates to a preparation method of a gasoline deep hydrodesulfurization catalyst material and a catalyst. The preparation method is as below: a related precursor microemulsion and an ammonia microemulsion are prepared; then the two are mixed for a reaction; and finally the mixture is subjected to flocculation, demulsification, sedimentation washing and roasting to obtain the gasoline deep hydrodesulfurization catalytic material with high specific surface area. Surface properties of product particles are controlled by changing the composition of the microemulsion system and the synthesis conditions, so as to modulate surface area and surface acidity of the composite material. The invention also provides a method for preparing a gasoline hydrodesulfurization catalyst by using the synthesized material as a carrier. The multi-component composite material is used to load active metal components by a microemulsion method, and the loaded metal has not only small particles but also high capacity. The ca |
