Abstract: A method for preparing tetrafluoropropene utilising three reactors is described. Each reactor comprises a catalytic bed containing a catalyst or a preliminary catalyst. The method comprises 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. A facility configured to implement the method is also described.
