HIGH PERFORMANCE VPO CATALYST AND PROCESS OF PREPARATION THEREOF. |
摘要 |
<p>An activated porous phosphorus/vanadium oxide catalyst adapted for the catalytic oxidation of a hydrocarbon to produce a carboxylic acid anhydride. The catalyst comprises shaped bodies having a B.E.T. surface area of at least about 15 m2/g, an average vanadium oxidation state of between about 4.0 and about 4.5, a total pore volume of at least about 0.15 cc/g, a normalized apparent shaped body density of between about 1.25 and about 2.0 g/cc, and a crush strength of at least about 4 pounds. At least about 5% of the pore volume of the catalyst is constituted of pores having a diameter of at least about 0.8 microns, and at least about 4% of the pore volume is constituted of pores having a diameter of at least about 10 microns. The catalyst is prepared by mixing a particulate phosphorus/vanadium oxide precursor with a pore modification agent to produce a modified catalyst precursor composition, forming the modified precursor composition into a predetermined shape, and removing the pore modification agent substantially at a temperature below 300 degrees C.</p> |
