| titleOfInvention | Hierarchical pore titanium silicalite molecular sieve catalyst with oxidative desulfurization effect and preparation method and application thereof |
| abstract | The invention belongs to the technical field of molecular sieves and preparation thereof, and discloses a hierarchical pore titanium silicalite molecular sieve catalyst with oxidative desulfurization, and a preparation method and application thereof. The preparation method comprises the following steps: mixing tetrapropylammonium hydroxide and deionized water, then dropwise adding ethyl silicate and butyl titanate, and stirring; transferring the mixture into a stainless steel autoclave, and statically drying in a drying oven at 180 ℃; centrifugally separating, washing, and drying in an oven at 80 ℃ overnight to obtain the molecular sieve; mixing a molecular sieve, sodium hydroxide, water and aspartic acid, stirring at room temperature, centrifugally filtering, drying filter residues in an oven at 80 ℃ for 10 hours, taking out the filter residues, heating the filter residues to 550 ℃ from room temperature at the speed of 2 ℃/min, and calcining the filter residues for 6 hours to obtain the catalyst. The conversion rate of the Si/Ti-20 molecular sieve catalyst for removing sulfide can reach 43% after 4h, and the reaction is a first-order kinetic reaction according to the kinetic simulation. |
