| titleOfInvention | Catalyst for preparing pyromellitic anhydride by oxidizing durene |
| abstract | The invention relates to a catalyst for preparing pyromellitic anhydride by oxidizing durene, which mainly solves the problems of low activity of the catalyst and more byproducts in the prior art, thereby resulting in low product yield. The invention adopts oxide catalyst which adopts alpha-Al 2 O 3 The silicon carbide, the ceramic ring or the mixture thereof is used as a carrier, and the active component comprises vanadium element, titanium element and at least one of VA group element and alkali metal element, thereby better solving the technical problem and greatly improving the yield of the catalyst to the pyromellitic dianhydride. |
