Process for the regeneration of a catalyst |
摘要 |
A process is provided for the regeneration of a vanadium-phosphorus oxide catalyst which has been used in a process for the preparation of maleic anhydride by oxidizing butane. The used catalyst particles are removed from the fluidized bed reactor and subjected to impact with each other and/or with structural surfaces such that the deteriorated layer is peeled away. Various forms of equipment may be employed such as pneumatic classifiers, jet mills and jetted fluidized beds. |
