Fixed-bed benzene Oxidation to Maleic Anhydride catalyst
Fixed-bed benzene Oxidation to Maleic Anhydride catalyst taking
Mixed oxide in the inert carrier,V2O5 and MoO3as active components,is used
In fixed-bed benzene oxidation to maleic anhydride. The catalyst possesses the
Characteristics of high activity,high intensity,98%-99% conversion rate,good
selectivity and upto 90%-95% yield. The catalyst has been treated with pre-activation
and processing longlife,the started induction period is reduced significantly,
The service life of the product is up to two years or more.

1. Using oil-benzene is best to the catalyst,because thiophene and total sulfur in benzene will lower the catalyst activity of operating,after the device is running normally,superfine coking benzene can be used.
2. In the process, the hot-spot temperature should not exceed 460℃.
3. The catalyst’s space velocity within 2000-2500 h -1 has the best effect.of course,if the space velocity is larger than this,it also works well,since it is the catalyst with high space velocity.
Package and transportation:
During the storage and transportation process, the catalyst is absolute moisture proof,waterproof and it should not exceed 3 months when it is placed in the air. We can flexibly package according to the customers’requires.
