| titleOfInvention | Process for preparing phosphorus-vanadium-oxygen catalyst precursors and catalysts |
| abstract | Heat treatment of phosphorus- vanadium-oxygen catalyst precursors at temperatures between about 150 DEG C. and about 300 DEG C. for a period of about 1 hour to about 6 hours prior to being subjected to calcination conditions yields catalyst precursors having increased crush strength and attrition resistance. The catalyst precursors, upon calcination at about 300 to 600 DEG C are converted to phosphorus- vanadium-oxygen catalysts which are useful for the conversion of non- aromatic hydrocarbons, particularly n- butane, to maleic anhydride. |
