摘要：
A high-density, medium-porosity catalyst, supported on a siliceous matrix and based on vanadium, iron, oxygen and alkali metals, wherein the V₂O₅ content ranges from 6 to 9% by weight, the Me₂O content ranges from 8.5 to 12% by weight (Me being an alkali metal), the particle density ranges from 1.10 to 1.40 g/cm³ and furthermore:
- the pore volume ranges from 0.20 to 0.70 cm³/g and the surface area ranges from 0.30 to 5 m²/g, the average radius of the pores ranging from 600 to 2200 nm;
- the SiO₂ content is at the most 75% by weight and the Fe₂O₃ content is at least 0.90% by weight.
- the pore volume ranges from 0.20 to 0.70 cm³/g and the surface area ranges from 0.30 to 5 m²/g, the average radius of the pores ranging from 600 to 2200 nm;
- the SiO₂ content is at the most 75% by weight and the Fe₂O₃ content is at least 0.90% by weight.
