demand for v2o5 az catalyst use
in sulphuric acid industr .Our
technical specification of
catalyst that we need is az below:

Application: Oxidation of
S02 to S03 for sulfuric acid
production.

Composition: Vanadium
pentoxide and alkali metal
sulfates on
special silica support


approx. 6% V20S

approx. 7% V20S

approx. 8%V20S
