I. Titanium Silicate Molecular Sieve Catalyst Dryer--Overview of Equipment

Titanium silicon molecular sieve (TS) has been a research hotspot in the field of molecular sieve catalysts in recent years due to its good catalytic performance. A large amount of literature reports have been published on the synthesis and application of the molecular sieve. Currently, TS-I having an MFI type structure, TS-2 having a MEL type structure, and TS-48 having a large pore structure have been synthesized. Such molecular sieves have excellent catalytic activity and directional oxidation performance for many organic oxidation reactions, such as epoxidation of olefins, hydroxylation of aromatic hydrocarbons, oxidation of cyclohexanone, oxidation of alcohols, etc., and they are good as redox molecular sieve catalysts. Application prospects. When the catalyst is regenerated, the titanium silicalite catalyst has to undergo multiple washing and drying processes. Different drying methods cause different degrees of difficulty in the drying process, especially affecting the recovery rate of the catalyst during the drying process, resulting in titanium silicon. The molecular sieve catalyst yield decreases and the cost increases.

In the case of the titanium-silicon molecular sieve catalyst, the aqueous solution of the titanium-silicon molecular sieve catalyst having a mass concentration of 5% to 20% is added to the vacuum-type drier, and the water vapor of 0. 3-0. 9Mpa is passed through the jacket of the dryer and stirred. Shaft jacket, indirect heating, drying catalyst, drying time is 3-6 hours, during the drying process, the vacuum degree is controlled at -0.2 Mpa (G)-OMpa (G), the vaporized water is removed from the vacuum pump outlet after dust removal Empty.

Titanium Silica Molecular Sieve Catalyst Dryer has high evaporation strength, uniform material drying, avoiding oxidation and overheating, and can obtain products with moisture content below 5%, and can be packaged without crushing operation. Titanium-silicon molecular sieve catalyst  dryer uses water as steam. Under the action of stirring, the material is fully mixed and exchanged in the cylinder, which reduces energy consumption and facilitates material recovery.
