The benzene oxidation to maleic anhydride catalyst is used in benzene oxidation to maleic anhydride by fixed bed.

  HTMAN-1 fixed-bed for benzene Oxidation to Maleic Anhydride catalyst
Product Description:
HTMAN-1 Benzene Oxidation to Maleic Anhydride takes a mixed oxide in the inert carrier as carrier, carries V2O5 and MoO3 as active components, using fixed-bed for benzene oxidation to maleic anhydride. This catalyst has high active, excellent strength, 98% -99% conversion rate, good selectivity and yield up to 90% -95%. Longevity of the catalyst after treatment, service life of two years. The catalyst has been dealed with the pre-treatment activation and longevity, the started induction period was reduced significantly, the life of the product is up to two years or more.

A typical use conditions:
Description:
1. Using oil-benzene is best to the catalyst, and thiophene and total sulfur in benzene will lower the catalyst activity. After run normal the device can use superfine coking benzene.
2. In the process the hot-spot temperature of the catalyst generally should not exceed 460 .
3. The catalyst space velocity within 2000-2500 h-1, has the best effect. Of course, the number is larger than this value is also ok, since it is the catalyst for high airspeed .
Packaging and Transport: In the storage and transportation process, The catalyst is absolute moisture proof, waterproof and placed in the air should not exceed 3 months. We can flexibly package according to the user requires.
