Detailed Product Description

Catalyst for Phthalic Anhydride production from oxidation of O-xylene(BC-239III)

The BC-239IIIcatalyst is a V₂O₅-TiO₂ supported catalyst used for the 70-90 gram processfixed bed oxidation of o-xylene to produce phthalic anhydride. The reactor is filled with different kinds of catalyst in two, three or four parts, which are of different activity and selectivity.

Performance:

1) High concertraction of o-xylene: 7090g/Nm³

2) Low reaction temperature: salt bath temperature: 350370

1)      Short induction period: the concentration of o-xylene can reach more than 80 g/Nm³ in 45~75days

2)      High space velocity and high yield: Yield of PA: ~113wt%

3)      High quality PA: the content of PTLD in crude PA≤0.15%

4)      Without adding SO₂

BC-239III catalyst is packed in pasteboard drums lining with double-layer woven sacks. Each drum contains about 35kg catalyst. The catalyst should be stored in a dry, clean, and well-ventilated place. Rolling, bumping, placing upside down, water and moisture should be avoided in both storage and transportation.
