| titleOfInvention | Method for producing carrierless catalyzers containing the mixed oxides of vanadium and phosphorus and in required case boron |
| abstract | The present invention relates to a process for the preparation of a non-carrier catalyst containing vanadium and phosphorus, and optionally mixed oxides thereof, wherein the phosphorus ratio to vanadium is between 1: 1 and 2: 1, such that a catalyst precursor of mixed oxides of vanadium and phosphorus is prepared. , the catalyst precursor is wet milled in a suspension of less than 10 µm, the ground catalyst precursor oil gives the hydroxide of the metals of Group IV-B of the Periodic Table, the ground catalyst precursor is recovered from the suspension and dried by spray drying technique, the dried catalyst precursor is calcined, and the dried catalyst precursor is calcined and then dried. calcined catalyst precursor is milled to below 10 μπι, such that the calcined catalyst precursor on the final milling line or thereafter with at least one phosphoric acid and, if desired, vanadium, the boron salt corresponding to the boron atomic ratio is treated with a water-soluble boron salt, the resulting catalyst is dried by spray drying technique and recalculated in a known manner. -1- |
