| titleOfInvention | Catalyst for preparing maleic anhydride by n-butane oxidation and preparation method thereof |
| abstract | The invention relates to a catalyst for preparing maleic anhydride by oxidizing n-butane. Mainly solves the problem of lower catalytic activity in the prior art. The main body of the invention comprises three elements of vanadium, phosphorus and oxygen, and a certain amount of metal auxiliary agent is added; the catalyst comprises the following components in percentage by weight based on the total weight of the catalyst: 26-35% of vanadium element, 14-20% of phosphorus element and 30-50% of oxygen element; the metal auxiliary agent is 0.02-7% of catalyst, and the catalyst is subjected to constant temperature and humidity treatment, multiple times of doping pore-forming agent and secondary forming treatment, so that the catalytic performance of the catalyst is improved, the strength of the catalyst is improved, and the catalyst can be applied to the field of preparing maleic anhydride by oxidizing n-butane. |
