Abstract
The invention relates to a drying method for titanium silicon molecular sieve catalyst. It characterized in that: titanium silicon molecular sieve catalyst solution is added into a vacuum harrow type dryer and is dried for 3 to 8 hours in the process of preparation and regeneration of titanium silicon molecular sieve catalyst to give dried titanium silicon molecular sieve catalyst. The catalyst can be produced in batches in enormous quantities with low catalyst consumption.
Description
Technical field
The present invention relates to a kind of drying means of titanium-silicon molecular sieve catalyst.
Background technology
HTS is a kind of new catalytic material, the various organic oxidizing reactions that participate in hydrogen peroxide had unique catalytic performance, the selectivity of product height, the reaction condition gentleness, environmental friendliness, but its catalysis of pimelinketone prepared by ammoxidation cyclohexanone oxime, but and catalysis carry out the epoxidation of alkene, the partial oxidation of alkane, the oxidation of alcohols and the hydroxylating of aromatic hydrocarbon ring etc.The titanium-silicon molecular sieve catalyst particle is little, has only about 0.2 μ m as common TS-1 catalyst one-level particle diameter.When Preparation of Catalyst or regeneration, titanium-silicon molecular sieve catalyst will be through processes such as washing, drying repeatedly, different drying modes causes the complexity difference in the drying process process, particularly can influence the yield of catalyst in the dry run, cause the decline of titanium-silicon molecular sieve catalyst yield, cost to increase.
Summary of the invention
The drying means that the purpose of this invention is to provide a kind of titanium-silicon molecular sieve catalyst.
The present invention is achieved in that when titanium-silicon molecular sieve catalyst preparation or regeneration, and titanium-silicon molecular sieve catalyst solution is added the vacuum rake dryer drying, controls certain drying time, obtains dried titanium-silicon molecular sieve catalyst.For the titanium-silicon molecular sieve catalyst moisture percentage is dropped to below 5%, be 3-8 hour drying time, is preferably 4-6 hour.
The Batch Process in enormous quantities of drying process when good effect of the present invention is to can be implemented in manufacturing or regeneration titanium-silicon molecular sieve catalyst.Its characteristics are that labour intensity is low, catalyst attrition is little.
The specific embodiment
Drying when embodiment 1. is applied to catalysis of pimelinketone prepared by ammoxidation cyclohexanone oxime and reacts the regeneration of used TS-1 type titanium-silicon molecular sieve catalyst.The aqueous solution that 100L is contained TS-1 type titanium-silicon molecular sieve catalyst 10% adds vacuum rake dryer, starts the drying machine shaft then, feeds Steam Heating to vacuum rake dryer, and the steam that evaporates is discharged outdoor by pipeline.Behind the dry 6h of catalyst solution, discharge from discharging opening.Dried catalyst is through detecting, and its water capacity is 2%.
Embodiment 2. is applied to the drying of the used titanium-silicon molecular sieve catalyst of catalytic epoxidation of propone system propylene oxide reaction.The aqueous solution that 100L is contained TS-1 type titanium-silicon molecular sieve catalyst 15% adds vacuum rake dryer, starts the drying machine shaft then, feeds Steam Heating to vacuum rake dryer, and the steam that evaporates is discharged outdoor by pipeline.Behind the dry 4h of catalyst solution, discharge from discharging opening.Dried catalyst is through detecting, and its water capacity is 3%.
Embodiment 3. is applied to the drying that catalysis of pimelinketone prepared by ammoxidation cyclohexanone oxime reacts used TS-1 type titanium-silicon molecular sieve catalyst.The aqueous solution that 100L is contained TS-1 type titanium-silicon molecular sieve catalyst 20% adds vacuum rake dryer, starts the drying machine shaft then, vacuumizes and feed the hot water heating to vacuum rake dryer, and the steam that evaporates is discharged outdoor by pipeline.Behind the dry 8h of catalyst solution, discharge from discharging opening.Dried catalyst is through detecting, and its water capacity is 1%.
Claims (2)
1. the drying means of a titanium-silicon molecular sieve catalyst, it is characterized in that: when titanium-silicon molecular sieve catalyst preparation or regeneration, titanium-silicon molecular sieve catalyst solution is added the vacuum rake dryer drying, and be 3-8 hour drying time, obtains dried titanium-silicon molecular sieve catalyst.
2. the described method of claim 1 is characterized in that be 4-6 hour drying time.
