Abstract
The present invention concerns a method for preparing tetrafluoropropene utilising three reactors each comprising a catalytic bed containing a catalyst or a preliminary catalyst, and comprising the implementation, separately in each of the reactors, of catalytic reactions or reactions regenerating the catalyst, the quantity of catalyst or preliminary catalyst in the catalytic bed of one of the reactors representing between 90% and 110% of the quantity of catalyst or preliminary catalyst contained in the catalytic bed of one of the other two reactors. The present invention also concerns a facility configured to implement the present method.
