摘要 |
<p>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/cm<3> and furthermore: - the pore volume ranges from 0.20 to 0.70 cm<3>/g and the surface area ranges from 0.30 to 5 m<2>/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.</p> |
